Momentum Mounts for Cable WiFi

Mari Silbey

If there was any doubt about the growing momentum behind cable WiFi, several recent milestones have done much to dispel it.

There was the rapid growth of public WiFi hotspots in 2013. The Cable WiFi initiative has grown to cover 250,000 hotspots, or close to it. There are the early investigations underway into small-cell field trials for extending mobile connectivity through WiFi, with Time Warner Cable Inc. (NYSE: TWC) admitting interest and Comcast Corp. (Nasdaq: CMCSA, CMCSK) reportedly testing the technology already. And there is the new WifiForward coalition that Time Warner, Comcast, and Charter Communications Inc. have all joined to lobby for expanded WiFi support in Washington, DC. (See Cable WiFi Hotspots Could Hit 1M in Year, TW Cable Eyes Small Cells Too, and Rival MSOs, Tech Rivals Unite on WiFi.)

Beyond these cable-specific initiatives, however, there is also important progress being made on the WiFi standards front. Next week at Mobile World Congress in Barcelona, the Wi-Fi Alliance and the Wireless Broadband Alliance (WBA) will jointly demonstrate a live Next Generation Hotspot (NGH) network supporting WiFi roaming.

In this case, roaming means that visitors will be able to use Passpoint-certified smartphones, tablets, and laptops tied to different service providers to discover and gain access to the conference's hotspot network. Authentication will be tied to the original service provider, but connectivity will be delivered through the local hotspot. Eighteen operators are signed up to participate in the demonstration, along with seven hardware vendors.

WiFi standards development is important because it has the potential to accelerate the adoption of more sophisticated WiFi services.

”What's really exciting here is that we're moving from a time of proprietary solutions, agreements based on... proprietary technology... to a time when you have both the technology with Passpoint and then the roaming infrastructure that NGH delivers such that you have something really very standards-based," said Kelly Davis-Felner, VP of Marketing for Wi-Fi Alliance, in an interview. "And there's a lot of leverage in that because everybody starts doing everything the same way."

While new standards should help all network operators, cable companies arguably have the most to gain. The rapid evolution of WiFi technology gives cable providers something they've never had before: a footprint outside the home.

There are multiple use cases for cable WiFi. Cable operators are already using these wireless networks to keep their current subscribers connected when they're outside the range of fixed broadband. As cable companies increase their geographic coverage, they'll also have more of an opportunity to package WiFi service and sell it to others.

Mobile carriers are good customer candidates in that case. Shrikant Shenwai, CEO of Wireless Broadband Alliance, believes there will be more roaming agreements announced in the near future where mobile operators bundle WiFi from partners with their own mobile services.

"Operators on both sides benefit because [there are] cable companies… who have the footprint and there are mobile operators who have the subscribers… You could actually create some interesting product packaging," said Shenwai.

Not all of the pieces are in place yet for the cable WiFi revolution. Network coverage is still limited for the moment, and a lot of consumer devices don't yet support the Passpoint standard, which enables many of the more advanced WiFi features available.

However, there are positive signs even where Passpoint is concerned. Davis-Felner noted that there was an inflection point in about the middle of 2013 where Passpoint-certified consumer devices began to overtake certified infrastructure equipment. Passpoint is also being integrated directly into mobile processors now, which will make it easier for more hardware vendors to support it.

For the cable industry, all of the evidence suggests that next-generation wireless services are on the near-term horizon. So the industry's WiFi momentum will likely continue.

Re: What spot hotspot?
As more roaming agreements become common among participants and the mobile infrastructure builds, it will only be to everyone's advantage to participate. The cable folks will certainly gain, while giving the public more valuable services on the go. But, defining the standars and getting agreement among the parties might be the difficult task ahead.

Right -- so this is how all cable operators are approaching WiFi?

Re: What spot hotspot?
MSOs deploy outdoor APs on strand, and in their indoor deployments, they put in another cable modem next to the customer's and hang an MSO managed AP on premise.  They then co-market the venue on the hotspot map and with Point of Presence signage.

What spot hotspot?
Mari -- Are cable operators deploying hotspots in a consistent way? Are any of them setting up independent infrastructure, or are they relying on customers (like stores, bars, etc.) to set up wifi zones?

A vital part of increasing the number of women in comms is transforming the ways companies can support and empower women. While progressive company policies that support both men and women in achieving work-life balance are a step in the right direction, creating a company culture that supports those policies can at times be more challenging.

During this show, we'll talk to Lynn Comp, Senior Director of Industry and Sales Enabling (ISE) in the Network Platforms Group at Intel, about why those challenges exist and how companies can overcome them. She'll provide insight into how Intel has worked to create a culture that supports work-life balance, and provide steps and guidance for other companies wishing to do the same. We will also leave plenty of time to get your questions answered live on the air.
