Wires Are The Exception

cropped-dsc_0734.jpg

Last week I went to go talk to a group of vocational students about networking.  While I was there, I needed to send a couple of emails.  I prefer to write emails from my laptop, so I pulled it out of my bag between talks and did the first thing that came to mind: I asked for the wireless SSID and password.  Afterwards, I started thinking about how far we’ve come with connectivity.

I can still remember working with a wireless card back in 2001 trying to get the drivers to play nice with Windows 2000.  Now, wireless cards are the rule and wired ports are the exception.  My primary laptop needs a dongle to have a wired port.  My new Mac Mini is happily churning along halfway across the room connected to my network as a server over wireless.  It would appear that the user edge quietly became wireless and no tears were shed for the wire.

It’s also funny that a lot of the big security features like 802.1x and port security became less and less of an issue once open ports started disappearing in common areas.  802.1x for wired connections is barely even talked about now.  It’s more of an authentication mechanism for wireless now.  I’ve even heard some vendors of these solutions touting the advantages of using it with wireless and then throwing in the afterthought comment, “We also made it easy to configured for wired connections too.”

We still need wires, of course.  Access points have to connect to the infrastructure.  Power still can be delivered via microwave.  But the shift toward wireless has made ubiquitous cabling unnecessary.  I used to propose a minimum of four cable drops per room to provide connectivity in a school.  I would often argue for six in case a teacher wanted to later add an IP phone and a couple of student workstations.  Now, almost everything is wireless.  The single wire powers a desk phone and an antiquated desktop.  Progressive schools are replacing the phones with soft clients and the desktops with teach laptops.

The wire is not in any danger of becoming extinct.  But it is going to be relegated to the special purpose category.  Wires will only live behind the scenes in data centers and IDF closets.  They will be the thing that we throw in our bag for emergencies, like an extra console cable or a VGA adapter.

Wireless is the future.  People don’t walk into a coffee shop and ask, “Hey, where’s the Ethernet cable?” Users don’t crowd around wall plates with hubs to split the one network drop into four or eight so they can plug their tablets in.  Companies like Aruba Networks recognized this already when they started posing questions about all-wireless designs.  We even made a video about it:

While I don’t know that the all-wireless design is going to work, I can say with certainty that the only wires that will be running across your desktop soon will be power cables and the occasional USB cord.  Ethernet will be relegated to the same class as electrical wires connected to breaker boxes and water pipes.  Important and unseen.

Maybe MU-MIMO Matters

Wireless

As 802.11ac becomes more widely deployed in environments I find myself looking to the next wave and the promise it brings.  802.11ac Wave 1 for me really isn’t that groundbreaking.  It’s an incremental improvement on 802.11n.  Wave 1 really only serves to wake up the manufacturers to the fact that 5 GHz radios are needed on devices now.  The real interesting stuff comes in Wave 2.  Wider channels, more spatial streams, and a host of other improvements are on the way.  But the most important one for me is MU-MIMO.

Me Mi Mo Mum

Multi-user Multiple-Input Multiple-Output (MU-MIMO) is a huge upgrade over the MIMO specification in 802.11n.  MIMO allowed access points to multiplex signals on different channels into one data stream.  It accomplished this via Spatial Division Multiplexing (SDM).  This means that more antennas on an access point are a very good thing.  It increases the throughput above and beyond what could be accomplished with just a single antenna.  But it does have a drawback.

Single-user MIMO can only talk to one client at a time.  All the work necessary to multiplex those data streams require the full attention of a single access point for the period in time that the client is transmitting.  That means that crowded wireless networks can see reduced throughput because of shorter transmit windows.  And what wireless network isn’t crowded today?

MU-MIMO solves this problem by utilizing additional antenna capacity to transmit multiple data streams at once.  If you have spare antennas, you can send another data stream.  The AP then takes the multiple streams and stitches them back together.  This means an effective increase in throughput for certain devices even though the signal strength isn’t as high (thanks to FCC power limits).  Here’s a great video from Wireless Field Day 7 that explains the whole process:

What I found most interesting in this video is two-fold.  First, MU-MIMO is of great benefit to client devices that don’t have the maximum number of spatial streams.  Laptops are going to have three stream and four stream cards, so their MU-MIMO benefit is minimal.  However, the majority of devices on the market using wireless are mobile.  Tablets and phones don’t have multiple spatial streams, usually just one (or in some cases two).  They do this to improve battery life.  MU-MIMO will help them out considerably.

The second takeaway is that devices without a high number of receive chains will make the AP do more work.  That’s because the AP has to process the transmit stream and prevent the extra streams from being transmitted toward the wrong client.  That’s going to incur processing power.  That means you’ll need an AP with a lot of processing power.  Or a control system that can crunch those numbers for you.

When you consider that a large number of APs in a given system are sitting idle for a portion of the time it would be nice to be able to use that spare capacity for MU-MIMO processing.  In addition, having those extra antennas available to help with MU-MIMO sounding would be nice too.  There’s already been some work done on the research side of things.  Maybe we’ll soon see the ability to take the idle processing power of a wireless network and use it to boost the client throughput as needed.


 

Tom’s Take

Wireless never ceases to amaze me.  When I started writing this article, I thought I knew how MU-MIMO worked.  Thankfully, Cisco set me straight at Wireless Field Day 7.  MU-MIMO is going to help clients that can’t run high-performance networking cards.  The kinds of clients that are being sold as fast as possible today.  That means that the wireless system is already being developed to support a new kind of wireless device.

A device that doesn’t have access to limitless power from a wall socket or a battery that lasts forever.  There’s been talk of tablets with increased spatial streams for a while, but the cruel mistress of battery life will always win in the end.  That’s why MU-MIMO matters the most. Because if the wireless device can’t get more powerful, maybe it’s time for the wireless network to do the heavy lifting.

Don’t Track My MAC!

track

The latest technology in mobile seems to be identification.  It has nothing to do with credentials.  Instead, it has everything to do with creating a database of who you are and where you are.  Location-based identification is the new holy grail for marketing people.  And the privacy implications are frightening.

Who Are You?

The trend now is to get your device MAC address and store it in a database.  This allows the location tracking systems, like Aruba Meridian or Cisco CMX, to know that they’ve seen you in the past.  They can see where you’ve been in the store with a resolution of a couple of feet (much better than GPS).  They now know which shelf you are standing in front of.  Coupled with new technologies like Apple iBeacon, the retailer can push information to your mobile device like a coupon or a price comparison with competitors.

It’s a fine use of mobile technology.  Provided I wanted that in the first place.  The model should be opt-in.  If I download your store’s app and connect to your wifi then I clicked the little “agree” box that allows you to send me that information.  If I opt-in, feel free to track me and email me coupons.  Or even to pop them up on store displays when my device gets close to a shelf that contains a featured item.  I knew what I was getting into when I opted in.  But what happens when you didn’t?

Wifi, Can You Hear Me?

The problem comes when the tracking system is listening to devices when it shouldn’t be. When my mobile device walks into a store, it will start beaconing for available wifi access points.  It will interrogate them about the SSIDs that they have and whether my device has associated with them.  That’s the way wifi works.  You can’t stop that unless you shut off your wireless.

If the location system is listening to the devices beaconing for wifi, it could be enabled to track those MAC addresses that are beaconing for connectivity even if they don’t connect.  So now, my opt-in is worthless.  If the location system knows about my MAC address even when I don’t connect, they can push information to iBeacon displays without my consent.  I would see a coupon for a camping tent based on the fact that I stood next to the camp stoves last week for five minutes.  It doesn’t matter that I was on a phone call and don’t have the slightest care about camping.  Now the system has started building a profile of me based on erroneous information it gathered when it shouldn’t have been listening.

Think about Minority Report.  When Tom Cruise is walking through the subway, retinal scanners read his print and start showing him very directed advertising.  While we’re still years away from that technology, being able to fingerprint a mobile device when it enters the store is the next best thing.  If I look down to text my wife about which milk to buy, I could get a full screen coupon telling me about a sale on bread.

My (MAC) Generation

This is such a huge issue that Apple has taken a step to “fix” the problem in the beta release for iOS 8.  As reported by The Verge, iOS 8 randomizes the MAC address used when probing for wifi SSIDs.  This means that the MAC used to probe for wifi requests won’t be the same as the one used to connect to the actual AP.  That’s huge for location tracking.  It means that the only way people will know who I am for sure is for me to connect to the wifi network.  Only then will my true MAC address be revealed.  It also means that I have to opt-in to the location tracking.  That’s a great relief for privacy advocates and tin foil hat aficionados everywhere.

It does make iBeacon configuration a bit more time consuming.  But you’ll find that customers will be happier overall knowing their information isn’t being stored without consent.  Because there’s never been a situation where customer data was leaked, right? Not more than once, right?  Oh, who am I kidding.  If you are a retailer, you don’t want that kind of liability on your hands.

Won’t Get Fooled Again

If you’re one of the retailers deploying location based solutions for applications like iBeacon, now is the time to take a look at what you’re doing.  If you’re collecting MAC address information from probing mobile devices you should turn it off now.  Yes, privacy is a concern.  But so is your database.  Assuming iOS randomizes the entire MAC address string including the OUI and not just the 24-bit NIC at the end, your database is going to fill up quickly with bogus entries.  Sure, there may be a duplicate here and there from the random iOS strings, but they will be few and far between.

More likely, your database will overflow from the sheer number of MACs being reported by iOS 8 devices.  And since iOS7 adoption was at 87% of compatible devices just 8 months after release, you can guarantee there will be a large number of iOS devices coming into your environment running with obfuscated MAC addresses.


Tom’s Take

I don’t like the idea of being tracked when I’m not opted in to a program.  Sure, I realize that my usage statistics are being used for research.  I know that clicking those boxes in the EULA gives my data to parties unknown for any purpose they choose.  And I’m okay with it.  Provided that box is checked.

When I find out my data is being collected without my consent, it gives me the creeps.  When I learned about the new trends in data collection for the grand purposes of marketing and sales, I wanted to scream from the rooftops that the vendors needs to put a halt to this right away.  Thankfully, Apple must have heard my silent screams.  We can only hope that other manufacturers start following suit and giving us a method to prevent this from happening.  This tweet from Jan Dawson sums it up nicely:

The Slippery Slope of Social Sign-In

FBTalons

At the recent Wireless Field Day 6, we got a chance to see a presentation from AirTight Networks about their foray into Social Wifi. The idea is that business can offer free guest wifi for customers in exchange for a Facebook Like or by following the business on Twitter. AirTight has made the process very seamless by allowing an integrated Facebook login button. Users can just click their way to free wifi.

I’m a bit guarded about this whole approach. It has nothing to do with AirTight’s implementation. In face, several other wireless companies are racing to have similar integration. It does have everything to do with the way that data is freely exchanged in today’s society. Sometimes more freely than it should.

Don’t Forget Me

Facebook knows a lot about me. They know where I live. They know who my friends are. They know my wife and how many kids we have. While I haven’t filled out the fields, there are others that have indicated things like political views and even more personal information like relationship status or sexual orientation. Facebook has become a social data dump for hundreds of millions of people.

For years, I’ve said that Facebook holds the holy grail of advertising – an searchable database of everything a given demographic “likes”. Facebook knows this, which is why they are so focused on growing their advertising arm. Every change to the timeline and every misguided attempt to “fix” their profile security has a single aim: convincing business to pay for access to your information.

Now, with social wifi, those business can get access to a large amount of data easily. When you create the API integration with Facebook, you can indicate a large number of discreet data points easily. It’s just a bunch of checkboxes. Having worked in IT before, I know the siren call that could cause a business owner to check every box he could with the idea that it’s better to collect more data rather than less. It’s just harmless, right?

Give It Away Now

People don’t safeguard their social media permissions and data like they should. If you’ve ever gotten DM spam from a follower or watched a Facebook wall swamped with “on behalf of” postings you know that people are willing to sign over the rights to their accounts for a 10% discount coupon or a silly analytics game. And that’s after the warning popup telling the user what permissions they are signing away. What if the data collection is more surreptitious?

The country came unglued when it was revealed that a government agency was collecting metadata and other discreet information about people that used online services. The uproar led to hearings and debate about how far reaching that program was. Yet many of those outraged people don’t think twice about letting a coffee shop have access to a wealth of data that would make the NSA salivate.

Providers are quick to say that there are ways to limit how much data is collected. It’s trivial to disable the ability to see how many children a user has. But what if that’s the data the business wants? Who is to say that Target or Walmart won’t collect that information for an innocent purpose today only to use it to target advertisements to users at a later date. That’s the exact kind of thing that people don’t think about.

Big data and our analytic integrations are allowing it to happen with ease today. The abundance of storage means we can collect everything and keep it forever without needing to worry about when we should throw things away. Ubiquitous wireless connectivity means we are never truly disconnected from the world. Services that we rely on to tell us about appointments or directions collect data they shouldn’t because it’s too difficult to decide how to dispose of it. It may sound a bit paranoid but you would be shocked to see what people are willing to trade without realizing.


Tom’s Take

Given the choice between paying a few dollars for wifi access or “liking” a company’s page on Facebook, I’ll gladly fork over the cash. I’d rather give up something of middling value (money) instead of giving up something more important to me (my identity). The key for vendors investigating social wifi is simple: transparency. Don’t just tell me that you can restrict the data that a business can collect. Show me exactly what data they are collecting. Don’t rely on the generalized permission prompts that Facebook and Twitter provide. If business really want to know how I voted in the last election then the wifi provider has a social responsibility to tell me that before I sign up. If shady businesses are forced to admit they are overstepping their data collection bounds then they might just change their tune. Let’s make technology work to protect our privacy for once.

Will Dell Buy Aerohive?

DELL-Aerohive-Logo

One rumor I keep hearing about in the industry involves a certain buzzing wireless vendor and the world’s largest startup.  Acquisitions happen all the time.  Rumors of them are even more frequent.  But the more I thought about it, the more I realized this may be good for everyone.

Dell wants to own the stack from top to bottom.  In the past, they have had to partner with printer companies (Lexmark) and networking companies (Brocade and Juniper) to deliver parts of the infrastructure they couldn’t provide themselves.  In the case of printers, Dell found a way to build them on their own.  That reduced their reliance on Lexmark.  In the networking world, Dell shocked everyone by going outside their OEM relationship and buying Force10.  I’ve talked before about why the Force10 pickup was a better deal in the long run than Brocade.

Dell’s Desires

Dell needs specific pieces of the puzzle.  They don’t want to be encumbered with ancillary products that will need to be jettisoned later.  Buying Brocade would have required unwinding a huge fibre channel business.  In much the same way, I don’t think Dell will end up buying their current wireless OEM, Aruba Networks.  Aruba has decided to branch out past the doing simple wireless and moved into wired network switches and security and identity management programs like ClearPass.  Dell doesn’t want any of that.  They already have an issue integrating the Force10 networking expertise into the PowerConnect line.  I’ve been told in the past the FTOS will eventually come to PowerConnect, but that has yet to happen.  Integrating purchased companies isn’t easier.  That becomes exponentially harder the more product lines you have to integrate.

Aruba is too expensive for Dell to buy outright.  Michael Dell spent a huge chunk of his cash to get his company back from the shareholders.  He’s going to put it on a diet pretty soon.  I would expect to see a few product lines slimmed down or outright dropped.  That makes it tough to justify buying so much from another company.  Dell needs a scalpel, not a sledgehammer.

Aerohive’s Aspirations

Aerohive is the best target for Dell.  They are clearly fighting for third place in the wireless market behind Cisco and Aruba.  Aerohive has never been shy about punching above their weight.  They have the mentality of a scrappy terrier that won’t go down without a fight.  But, they are getting pressure to expand quickly across their product lines.  They took their time releasing an 802.11ac access point.  Their switching offering hasn’t caught on in the same way that of Aruba or Meraki (now a division of Cisco).

Aerohive is on the verge of going public.  I’m sure the infusion of cash would allow them to pay off some early investors as well as fund more development for 802.11ac Phase 2 gear and maybe a firewall offering.  The risk comes when you look at what happened to Ruckus Wireless shortly after their IPO.  While they did recover, it didn’t look very good for a company that supposedly did have a unique claim, their antenna design.  Aerohive is a cloud management platform like many others in the market.  You have to wonder how investors would view them.  Scrappy doesn’t sell stock.

Aerohive is now fighting in the new Gartner “Wired and Wireless Access” magic quadrant, which is an absolute disaster for everyone.  An analyst firm thinks that wireless is just like wired, so naturally it makes sense for AP vendors to start making switches, right?  Except the people who are really brilliant when it comes to wireless, like Matthew Gast and Victor Shtrom couldn’t care less about bits on copper.  They’ve spent the better part of their careers solving the RF problems in the world.  And now someone tells them that interference problems aren’t that much different than spanning tree?  I would have long since planted my head permanently onto my desk if I’d been told that in their position.

Aerohive gains a huge backer in the fight if Dell acquires them.  They get the name to go up against Cisco/Meraki.  The gain R&D from Dell with expertise around cloud management.  They can start developing integration with HiveManager and Dell’s SMB extensive product line.  Switch supply becomes a thing of the past.  Their entire software offering fits well with what Dell is trying to accomplish from a device independence perspective with regards to customers.

Tom’s Take

I don’t put much stock in random rumors.  But I’ve heard this one come up enough to make me ask some tough questions.  There are people in both camps that think it will happen sometime in 2014.  Dell has to get the books sorted out and figure out who’s in charge of buying things.  Aerohive has to see if there’s enough juice left in the market to IPO and not look foolish.  Maybe Dell needs to run the numbers and find out what it would take to cash out Aerohive’s investors and add the company to the growing Empire of Round Rock.  A little buzz for the World’s Largest Startup couldn’t hurt.

Cisco CMX – Marketing Magic? Or Big Brother?

Cisco Logo

The first roundtable presenter at Interop New York was Cisco. Their Enterprise group always brings interesting technology to the table. This time, the one that caught my eye was the Connected Mobile Experience (CMX). CMX is a wireless mobility technology that allows a company to do some advanced marketing wizardry.

CMX uses your Cisco wireless network to monitor devices coming into the air space. They don’t necessarily have to connect to your wireless network for CMX to work. They just have to be beaconing for a network, which all devices do. CMX can then push a message to the device. This message can be a simple “thank you” for coming or something more advanced like a coupon or notification to download a store specific app. CMX can then store the information about that device, such as whether or not they joined the network, where they went, and how long they were there. This gives the company to pull some interesting statistics about their customer base. Even if they never hop on the wireless network.

I have to be honest here. This kind of technology gives me the bit of the creeps. I understand that user tracking is the hot new thing in retail. Stores want to know where you went, how long you stayed there, and whether or not you saw an advertisement or a featured item. They want to know your habits so as to better sell to you. The accumulation of that data over time allows for some patterns to emerge that can drive a retail operation’s decision making process.

A Thought Exercise

Think about an average person. We’ll call him Mike. Mike walks four blocks from his office to the subway station every day after work. He stops at the corner about halfway between to cross a street. On that street just happens to be a coffee shop using something like CMX. Mike has a brand new phone that uses wifi and bluetooth and Mike keeps them on all the time. CMX can detect when the device comes into range. It knows that Mike stays there for about 2 minutes but never joins the network. It then moves out of the WLAN area. The data cruncher for the store wants to drive new customers to the store. They analyze the data and find that lots of people stay in the area for a couple of minutes. They equate this to people stopping to decide if they want to have a cup of coffee from the shop. They decide to create a CMX coupon push notification that pops up after one minute on devices that have been seen in the database for the last month. Mike will see a coupon for $1 off a cup of coffee the next time he waits for the light in front of the coffee shop.

That kind of reach is crazy. I keep thinking back to the scenes in Minority Report where the eye scanners would detect you looking at an advertisement and then target a specific ad based on your retina scan. You may say that’s science fiction. But with products like CMX, I can build a pretty complete profile of your behavior even if I don’t have a retina scan. Correlating information provides a clear picture of who you are without any real identity information. Knowing that someone likes to spend their time in the supermarket in the snack aisles and frozen food aisles and less time in the infants section says a lot. Knowing the route a given device takes through the store can help designers place high volume items in the back and force shoppers to take longer routes past featured items.


Tom’s Take

I’m not saying that CMX is a bad product. It’s providing functionality that can be of great use to retail companies. But, just like VHS recorders and Bittorrent, good ideas can often be used to facilitate things that aren’t as noble. I suggested to the CMX developers that they could implement some kind of “opt out” message that popped up if I hadn’t joined the wireless network in a certain period of time. I look at that as a way of saying to shoppers “We know you aren’t going to join. Press the button and we’ll wipe our your device info.” It puts people at ease to know they aren’t being tracked. Even just showing them what you’re collecting is a good start. With the future of advertising and marketing focusing on instant delivery and data gathering for better targeting, I think the products like CMX will be powerful additions. But, great power requires even greater responsibility.

Why Do We Tolerate Bad Wireless?

HotelSpeedConnection

If there is one black eye on the hospitality industry, it has to be wireless.  I don’t think I’ve ever talked to anyone that is truly happy with the wireless connectivity they found in a hotel.  The above picture from an unnamed hotel in Silicon Valley just serves to underscore that point.  When I was on a recent speaking trip in New England, I even commented about the best hotel wireless I’d ever seen:

Granted, that was due to a secluded hotel on MIT‘s university network, but the fact remains that this shouldn’t be the exception.  This should be the rule.

Thanks to advances in mobile technology like LTE, we have a new benchmark for what a mobile device is capable of producing.  My LTE tablet and phone outrun my home cable connection.  That’s fine for browsing on a picture frame.  However, when it’s time to get real work done I still need to fire up my laptop.  And since there isn’t an integrated LTE/4G hotspot in my MacBook, I have to rely on wireless.

Wireless access has gone from being a kitschy offering at specialized places to being an everpresent part of our daily lives.  When I find myself in need of working outside the office, I can think of at least five different local establishments that offer me free wireless access.  Signing up for mobile hotspot services easily doubles that number.  There are very few places that I go any more that don’t give me the ability to use WiFI.  However, there is a difference between having availability and having “good” availability.

Good Enough Wireless

I would never upload video at a coffee shop or an airport.  The sheer number of folks using the network causes massive latency and throughput issues.  Connections are spotty and it’s not uncommon to see folks throw their hands up in the air because something just randomly stopped working.  However, the most telling statistic is how often we will go back to that same location to use the free wifi again.

Hotels have a captive audience.  You’re there to attend a conference during the day or spend the night.  You are geographically isolated.  You get what you get when it comes to connectivity.  Newer hotel chains that focus on business travelers understand the need for wireless connectivity.  They usually offer it for free with your room.  That’s because they usually have the infrastructure to support wireless coverage from large numbers of guests.  Older hotels that aren’t quite up to snuff or don’t understand why travelers need Internet access usually charge exorbitant fees or bundle the wireless into a “resort” package that gives you a whole bunch of high-margin useless services to get what you want.  Sometimes they use those fees to upgrade the infrastructure.  Or they just pocket the money and go on with their day.

Internet In My Pocket

As much as we complain about terrible wireless at hotels, it’s not like we have an alternative.  Wireless hotspot devices, commonly called “MiFis” after the Verizon branding, are popular with real road warriors.  Why hunt for a coffee shop when you can fire up a wireless network in your pocket?  Most current mobile devices even come with hotspot functionality built in.  But the carriers haven’t gotten the message yet.  For every one that allows hotspot usage (Verizon), you have those that don’t believe in hotspot and want to gouge you with higher fees or data plan changes to revamp bad mobile data decisions in the past.  Yes, I’m looking right at you AT&T.

Mobile hotspots can fix wireless problems in isolated cases, but loading a hotel full of people on MiFis will inevitably end in disaster.  Each of them uses a portion of the LTE/4G spectrum.  Think about a large gathering where everyone’s mobile phones cause spotty reception.  Not because they are all in use, but because they just happen to be occupying the same space.  Towers get overloaded, backhaul networks slow down, and service suffers for everyone.  If you don’t believe me, try making a phone call at Cisco Live some time.  It’s not pretty.

As long as there are no options for solving the problem, hospitality will go right on offering the same terrible coverage they do now.  As far as they are concerned, wireless is best effort.  Best effort should never be acceptable.  You can fix this problem by going to the front desk and telling them all about it.  No, don’t yell at the desk attendant.  They have zero control over what’s going on.  There’s a better way.

Satisfaction Not Guaranteed

Ask for a satisfaction survey.  Fill it out and be brutally honest when you get to the “Are You Pleased” section.  Those surveys go right up the chain into the chain satisfaction ratings.  If they start getting disgruntled comments about bad wireless coverage, I can promise that some Quality Champion somewhere is going to look into things.  Hotels hate black eyes on their satisfaction ratings.  Bad reviews keep people from staying at a hotel.  If you want to get the wireless fixed, tell them how important it is.  Tell them you’ll stay somewhere else next time because you can accomplish anything.  Voting with your wallet is a sure fire way to make an impact.

Tom’s Take

I remember the old Cingular/AT&T Wireless commercials with the cell phones cutting out during calls.  I laughed and thought about all the times it had happened to me.  It because such a sticking point that every carrier worked to upgrade their network and provide better call quality.  No one would stand for spotty service any more as they began to rely on their mobile phones as their primary communications devices.

Wireless is the same now as cell phones were then.  We need a concerted effort to upgrade the experience for everyone to make it usable for things like Hotspot 2.0, which will offload traffic from LTE to WiFI seemlessly.  We can’t let terrible wireless rule us like spotty cell phone coverage did years ago.  Do everything you can to make wireless useful for everyone.
