Wireless Predictions for 2010

January 4th, 2010

Certainly no calendar flip would be complete without a laundry list of predictions for the new year. FierceWireless has put together a compelling predictions for the wireless industry. To summarize:

  • Palm will be purchased by another handset vendor
  • Pricing, coverage issues will hinder cable companies’ wireless offerings
  • Sprint Nextel’s 4G leadership will help revive the carrier
  • Huawei will get one LTE deal in North America
  • At least one wireless carrier will experiment with usage-based data pricing
  • Motorola will show some signs of recovery thanks to Android (last year, FierceWireless predicted “Motorola’s handset division will cease to be“)
  • Computer makers’ attempts at Android smartphones will flounder

New technologies that will change “everything”

October 27th, 2009

Yes, well I don’t know about changing everything, but a few days ago, Glenn Fleishman wrote about 3D TV, HTML5, video over Wi-Fi, superfast USB, and mobile augmented reality as being key breakthrough technologies emerging over the next few years. While there are certainly many such lists to be made, I think Glenn’s done a nice job detailing this particular set of five technologies for us.

He rightly dubs USB as one of the “least-sexy technologies” built into present-day computers and mobile devices, but speeding it up by an order of magnitude is a game changer. And in fact, USB 3.0 (a.k.a. SuperSpeed) should deliver more than 3.2 gbps of actual throughput. The results will introduce major changes in device connectivity, computer backup (coupled with coming advances in flash drives), and video (replacing HDMI?).

By 2012, two new WiFi protocols–802.11ac and 802.11ad–are expected to handle over-the-air data transmission at 1 gbps or faster. Glenn does a nice job of pointing out that the high speed transfers will work well “moving data across short distances between devices in the same room.” He quotes Allen Huotari, the technical leader at Cisco as saying “home networks won’t result from “any one single technology in the home, but rather a pairing of technologies or a trio of technologies–wired and/or wireless–for the backbone and the wireless on the edges.” With one foot firmly in the G.hn camp, Rainier concurs.

Then we come to 3D TV. Could the makers of the old red and blue cardboard eyeglasses ever have envisioned the coming active-shutter approach to 3D simulations? What Hollywood has historically called “depth enhanced movies” are now moving more toward the promise of real 3DTV, an immersive, true-to-life experience that’s nothing like anything we’ve seen before.

Augmented Reality?

Augmented Reality?

My favorite part of Glenn’s article is his discussion of “augmented reality.” First of all, the phrase itself, with or without quotation marks, pulls us immediately into the philosophical domain. I personally think that until we can artificially stimulate our cranial neurons to have choreographed experiences, reality is still reality.

Technologies like heads-up displays, etc. are terrific tools for enhancing safety, efficiency, etc., but they are still tools (is a compass – once an exceedingly innovative high-tech device, “augmented reality?”)

Glenn’s final breakthrough, HTML5, sounds a little dull until you consider it might may do away with the need for audio, video, and interactive plug-ins, and will let designers create Websites that work essentially the same on every browser–whether on a desktop, a laptop, or a mobile device. Yeah, actually, that would be kind of awesome.

Two-Year Study of Global Internet Traffic

October 14th, 2009

Arbor Networks (along with the University of Michigan and Merit Network) have put together the “Internet Observatory Report” which they say is the largest study of global Internet traffic ever. The report analyzes two years worth of detailed traffic statistics from 110 large and geographically diverse cable operators, international transit backbones, regional networks and content providers. 

internet-speedWhile the report includes discussion around significant changes in Internet topology and commercial inter-relationships between providers; analysis of changes in Internet protocols and applications; it is the concluding analysis of Internet growth trends and predictions of future trends that provides the most interesting food for thought.

Whereas five years ago, Internet traffic was distributed fairly evenly across tens of thousands of web sites and servers around the world, most content has now clustered around a small number of very large hosting, cloud and content providers.

Out of the 40,000 routed end sites, 30 large companies (what Arbor calls “hyper giants”) like Limelight, Facebook, Google, Microsoft and YouTube now generate and consume 30% of all Internet traffic.

In addition, while Internet applications historically communicated across numerous application-specific protocols and communication stacks, just a few web and video protocols now dominate (including video over web and Adobe Flash). Arbor says other mechanisms for video and application distribution like P2P (peer-to-peer) have declined dramatically in the last two years (this drop seems to be what most people are focusing on, but I personally don’t find it that surprising).

The report’s final key finding is that macroeconomic forces have “radically transformed” the global Internet ecosystem. A wave of innovation is ongoing, says Arbor, with service providers now offering everything from triple play services to managed security services, VPNs and increasingly, CDNs.

I can’t help but agree strongly that these changes in particular have significant and ongoing implications for backbone engineering, design of Internet scale applications and research.
