GigaOM White Paper: The Facts & Fiction of Bandwidth Caps

Tue, 30 Sep 2008 02:18:09 -0700

Beginning on Wednesday, Comcast, the largest broadband service provider in the U.S., is going to start capping the total amount of data you can transfer using their broadband connection — to 250GB per month. With this move, the cable company will become the symbol of a new Internet era, one that is both monitored and metered. It is an era that threatens to limit innovation and to a large extent, the possibilities for new startups.

I have been very vocal about the short-sightedness of this decision being made by Comcast (and some other carriers), and along with my colleague Stacey Higginbotham, have been covering the story pretty closely. It is a clear and present danger to the way we use the Internet in this country.

In order to give you a better understanding of the issues at hand, I have teamed up with my old friend Muayyad Al-Chalabi, an alumni of Bell Labs and until recently an analyst with The Monitor Group, to release this white paper, “Broadband Usage-Based Pricing and Caps Analysis.”

In this paper, we aim to highlight the possible unintended consequences of such policies, among them the stunting of growth and innovation of web-based applications. And of course, higher costs. Plus:

The strategy ignores the high degree of dependency “interactions” between power users and the rest of the network. The power users don’t act in isolation and in fact represent the hubs in any scale-free network; sequestering them and overcharging them will result in either low usage or worse, higher costs.
Given the growth trend due to consumers’ changes in content consumption, today’s power users are tomorrow’s average users. By 2012, the bill for data access is projected to be around $215 per month.
Strategic pricing involves the recognition that changing prices alone cannot solve the challenges facing carriers. Carriers are taking the easy way out trying to protect the “walled garden” rather than figuring out how to innovate in service delivery and harvesting more value from the overall content and applications opportunity.

Is T-Mobile Spinning on Google Phone Bandwidth Caps?

Wed, 24 Sep 2008 22:18:34 -0700

There are many problems with T-Mobile USA’s 3G plans, as we outlined yesterday. None compare to the seemingly foolish 1 GB bandwidth cap on “unlimited” data plans they are hawking along with the Google Phone. Today, in response to a New York Times query, they seemed to have backed away from the cap.

We removed the 1GB soft limit from our policy statement, and we are confident that T-Mobile G1 customers will enjoy the high speed of data access over our 3G network. The specific terms for our new data plans are still being reviewed and once they are final we will be certain to share this broadly with current customers and potential new customers.

The Times might be satisfied by the explanation, but like some others, I am not buying this story just yet. When T-Mobile says they are still figuring out specific terms for new data plans, it smacks of double speak. Does the company really mean to say that they are going to be imposing a bandwidth cap, though it would be north of 1 GB? If not, they could simply would have said: no caps whatsoever.

By the way, Verizon Wireless, the master of double speak, imposed a 5GB bandwidth cap on its “unlimited” data plans. As an aside, I think it’s time folks stop issuing misleading advertising by saying “unlimited” data for X-amount of dollars.

VoIP, 3G Roaming & G1, aka the Google Phone

Tue, 23 Sep 2008 16:11:35 -0700

So the big day is finally here: Google has released its Android operating system, the latest entrant into the mobile OS wars.

The Android-based, HTC-made G1 was launched earlier today at a ceremony in New York, and among the attendees were our intrepid reporters Liz Gannes and Craig Rubens. After getting a first-hand look at the device, they promptly called me and compared it to the iPhone. (Coverage from across the network can be found here.)

But from a VoIP, data and broadband perspective, I still had questions. And when I finally got them answered, it became clear to me that Android isn’t nearly as “open” as Google and T-Mobile’s hype machine would have you believe. In fact, the most you could say about G1 is that it’s “almost open.”

Anyway here are our findings, which could come in handy if you’re trying to decide whether or not to buy this device:

VoIP: Google’s GTalk will work at launch as an IM client but you wouldn’t be able to use it to make any voice calls. Since the OS is open, there are no restrictions on VoIP apps, the company claims. Yet at the same time while T-Mobile has no restrictions on VoIP over Wi-Fi, but it says currently has no plans to support VoIP on their (3G) mobile network, either, a position in line with Apple and AT&T. This is hardly the open approach that was being touted by Google.

Android Marketplace: As for getting into the Android Marketplace, Google will “validate” all the apps but are providing no details as to how that will work, only to say that it will be as easy as possible. Again, the approach is no different (and not quite open) when compared to Apple.

3G & Wireless Broadband Roaming: T-Mobile says it’s boosting its network so that 94 percent of its U.S. subscribers will have 3G access. It will use 3G in the U.S. and Europe and yes, a U.S. user will be able to use the same U.S. device on European 3G networks. All of the phones will have the capability to use both 3G networks; all the phones will be dual-band. (See also 4 Things You Need Know About T-Mobile 3G)

Bandwidth Caps: Earlier it was reported that there would be a 1GB bandwidth cap on the so-called unlimited data plan. Google and T-Mobile spokespeople say there are no bandwidth limitations or caps on the phone and that all plans come with unlimited data. But it’s hard to take their word for it, especially when T-Mobile’s own web site hawking the G1 phone claims that after 1GB of data is used up in a billing cycle, “data throughput for the remainder of that cycle may be reduced to 50 kbps or less. Your data session, plan, or service may be suspended, terminated, or restricted for significant roaming or if you use your service in a way that interferes with our network or ability to provide quality service to other users.”

With additional reporting from Craig Rubens.
