WiMAX News

November 16, 2005: WiBro Demonstrated in South Korea

KT has shown off the homegrown mobile wireless data standard, WiBro: Thestandard has aspects of mobile WiMax and cellular technology, and may wind upconverging with international mobile standards in the future. KT claims access atspeeds of up to 60 kilometers per hour. They have two access devices that canfunction as WiBro modems and for voice calls. The service will roll out in 2006.

February 21, 2006: Proxim Wireless Launches 3.5 GHz Products Ots Tsunami MP-16 uses the 3.5 MHz licenced band in Europe and Asia. The

company says the product is in trials with nine firms. This band is not yet sortedout for use in the US, but is widely expected to lead licensed fixed WiMaxdeployments in Europe. The product is in queue for certification.

January 19, 2006: First Certified WiMax Products Announced Aperto, Redline, Sequans and Wavesat have passed the first, simple round of

testing which covers just a simple air link, and is so limited that a number ofcompanies, including Alvarion, sat this round out.

The four companies who have WiMax certification will certainly trumpet the fact,but it doesnt change the dynamics of the industry. These initial certifications workin the 3.5 GHz band

The press release from the WiMax Forum notes that the Spanish testing lab has 26reservations for base station and customer premises equipment in the queue,which will be completed over the next two months. Subsequent waves of testingwill cover more and more aspects of WiMax performance and interoperability, suchas quality of service and advanced radio features.

More NEWS

Nortel Builds Vast Albertan WiMax Network Nortel will roll out 8,000 square miles of WiMax: A governmental group and Nortel

will build the network designed for 1 to 3 Mbps of access in heavily underservedareas of the province.

December 07, 2005: Mobile 802.16e Standard Approved The basis for what will be mobile WiMax was approved by the IEEE today: Now

that the standard is done, the hard part is developing hardware and replicatingcellular infrastructure. All the challenges that faced rolling out 3G networks, landand planning rights for transmitters, etc. equally apply to mobile WiMax. Add tothat, that its a new standard without the real-world evolution thats happened inthe mobile world, and theres going to be a long lag between today and real,functioning, interoperable mobile WiMax equipment.

Over the next two to three years, however, well be reading stories every week inthe mainstream press that continue to inflate the abilities of fixed WiMaxsomething mobile carriers are said to be very interested in for licensed use to

backhaul tower trafficand mobile WiMax. Fixed WiMax doesnt operate inmoving vehicles dozens of miles from a base station running at 72 Mbps. It canrun fast, far, and mostly static, and not all three: you get fast when youre closeup and slow when youre far away.

TechDirt is saying it will be 2008 before we see anything resembling real mobileWiMax given the timetable that took fixed WiMax from 802.16 standards work to aratified proposal to the very first stages of certification that dont offer realinteroperable benefits today.

And Lastly

November 11, 2005: Intel Makes Global WiMax Investment ZDNet reports that Intel released a slew of money around the

world for WiMax development: This includes a $1.12 billioncontract for a project in Taiwan, which will agree to provide thenecessary spectrum for the work. The project will begovernment-assisted until 2008 to bring businesses into the fold.

The article says Intel has 13 more Europe and Americas networksup and running, with 10 more theyve sponsored due to appearby years end. This includes projects in The Dominican Republicand Austria

The Future for WiMAX

There are four end-game results for WiMAX:1. The market share secured by non-WiMAX operators will be so large that

WiMAX, in either its fixed or mobile value proposition, will simply not beable to get a foothold to deliver on the scale economics promised andwill ultimately die or be relegated to niche applications such as wirelessbackhaul. This is a multi-standard outcome since multiple non-WiMAXstandards might exist. (3G, Flash-OFDM and UMTS-TDD, 802.20)

2. The massive industry support for WiMAX and the technical superiorityof the standard over some of the other mBWA technologies willencourage non-WiMAX operators to upgrade gradually to WiMAX, andnew operators entering the market will automatically support WiMAX.This is a single standard outcome.

3. The existing non-WiMAX operators will continue to support their mBWAtechnologies while the new operator entrants will deploy WiMAX. This isa multi-standard outcome.

4. One of the non-WiMAX, proprietary standards sees a high level of earlymarket traction and is able to establish itself as a de facto standardbefore WiMAX can gain any momentum. This is a single standardoutcome.
