Cable Banking on WiFI

Wi-FiI’ve been reading a lot lately about the massive effort that cable companies are putting into expanding their WiFi networks. It’s estimated that Comcast and Cablevision together now have almost 9 million public hotspots, most of which come from dual routers in subscribers homes that provide a hotspot link along with the subscriber’s link. There are about another 1.5 million hotspots deployed by Cox, Time Warner and Bright House.

At this point nobody is quite sure how the cable companies are going to monetize this business. Several years ago some standards were developed by the Wi-Fi Alliance to create interoperability between WiFi networks and cellular networks. The idea was to allow cellular companies to offload overflow cellular traffic onto commercial WiFi networks when their cell sites get too busy.

But there are still changes needed in the industry for this to take place. First, a lot more phones need to be enabled to make calls on WiFi, a feature that is now included on the IPhone, but which few people have enabled. Probably the most important thing still lacking is the brains in the networks that will allow easy WiFi roaming so that a call or data transmission can be handed from one WiFi hotspot to another without needing a new verification and login and without restarting a given transmission. Until WiFi roams smoothly you won’t be able to continue a WiFi voice call without being cut off every time you change to a new hotspot. This might not be solved until the whole cellular network moves into the cloud using software defined networking so that the brains that are behind the handoffs of cellular calls can be applied to other types of connections.

But in high traffic areas where there is a lot of foot traffic, WiFi certainly can relieve the data traffic on cellular networks. But are the cellular companies really willing to pay for this? Already today WiFi is carrying a lot of data for cellular-enabled devices for free (to the cellular companies). Adobe published statistics recently that show that 93% of data on tablets and 43% of data on smartphones is carried by WiFi. But one would have to think that the vast majority of this is done in people’s homes and offices where they spend most of their time.

There is no doubt that having somebody else carry their data traffic is a benefit to cellular companies, but that doesn’t mean that they are going to be willing to write checks to WiFi hotspot owners for carrying cellular data. There has been no news of Comcast or the other cable companies making such deals with cellular companies, and so one would think this application is mostly speculation.

One also has to wonder about the efficacy of the current cable hotspots. The majority of Comcast hotspots are going to come from home routers that have been equipped to provide a public WiFi connection as well as the in-home connection for customers. But how useful are these connections? If you’ve ever walked around outside your house looking to connect to your own WiFi network I think you understand that reception outside of your home is sketchy. There are places where the signal is clear, areas where it is poor and areas where it doesn’t exist.

I look at my own house and wonder how valuable it is for Comcast to enable my hotspot. I get joggers and dog walkers by here on the front sidewalk, but otherwise this is not a neighborhood with much foot traffic. The only circumstances where my WiFi might have value is if workmen at my house use it, or if one of my immediate neighbors obtains a Comcast password from somebody and uses my WiFi for free. Otherwise, somebody would need to sit on my front porch or park in my driveway to get WiFi, something I would frown greatly upon.

There are a few ways that Comcast can monetize WiFi. One is to sell roaming WiFi as a service, much like you get in an airport. But to sell that service requires large areas of good coverage. And there are places like that. For example, it’s been reported that Comcast has blanketed the Jersey shore with coverage, and so selling a data connection to non-Comcast customers in these kinds of areas is a possibility.

I think the best business opportunity is for Comcast to get into the cellular business using WiFi enabled phones. They could sell cellular plans that either use only WiFi, or that use WiFi first and use cellular as the back-up. A lot of people mostly use their cellphones in homes and offices and such callers could save a lot of money if Comcast prices it right. Assuming that they could strike a deal with one of the four major spectrum holders they ought to be able to undercut the major carrier’s prices and still be profitable with such products.

But nobody knows for sure why Comcast and the other cable companies are doing this because they haven’t said. They must have something in mind, because they are spending a lot of money on public hotspots. One would certainly hope that Comcast has something in mind since they are antagonizing their cable modem customers yet again by turning them into public hotspots without their permission.
