WiMAX is Easy as ABC


We’ve been writing about "wifi on steroids" — or WiMAX — since the earliest days of the Really Rocket Science blog, when it was but a dream on the technological horizon.

These days, understanding the deployment and growth of WiMAX  is as easy as A-B-C.

A is for Alaska, where AT&T Alascom, which has been using satellites to deliver telecom across Alaska since 1974, is rolling out WiMAX using  Alvarion Ltd.’s BreezeMAX 2.3 GHz TDD equipment:

 Alvarion’s solution is capable of delivering flexible and enhanced coverage even in difficult terrain, such as the hilly and wooded areas. In addition, Alvarion’s nomadic self-install Si CPE can incorporate a patent-pending fast-switching algorithm with six integrated antennas. The Si can is available with a wide variety of options, from multiple POTS interfaces to built-in Wi-Fi.

To deliver WiMAX, AT&T Alascom utilizes SES-Americom’s AMC-8 satellite (also known as Aurora III) exclusively.

Rumors also have AT&T deploying WiMAX in the South soon:

AT&T Inc. is preparing to launch WiMax services during the second quarter of 2008, Unstrung has learned from an industry source. The services will likely be in the South of the U.S. where the operator has suitable licenses for broadband wireless services.

The cellular giant is planning to deploy limited WiMax services in the 2.3 GHz band that could be used as a fixed-wireless alternative to DSL or cable offerings, the source says. AT&T is said to have its suppliers for the service lined up now.


B is for Breezemax; Alvarion of Israel is making real progress in selling their BreezeMAX system for WiMAX apps:


Commercially available since mid 2004, deployed by over 150 operators in more than 30 countries, BreezeMAX is the most advanced, field proven commercial WiMAX solution and the first to offer CPE powered with Intel PRO/Wireless 5116 broadband interface WiMAX chip.


Built from the ground up based on the IEEE 802.16-2004 standard, BreezeMAX supports fixed, nomadic and portable services with a clear path for the emerging WiMAX mobile industry based on the IEEE 802.16e standard. BreezeMAX is designed for a variety of frequencies in both licensed and license-exempt bands from 2GHz to 6GHz spectrum, and operates in both FDD and TDD duplex modes.

Check out this long list of PDF case studies to see how Breezemax is deployed worldwide.

But C isn’t for "check out" — it’s for the Caribbean, where Digicell is rolling out WiMAX using Alvarion products, most recently in Cayman Islands using AMC-6.

Given the continuing rapid growth in WiMAX deployment, we could probably go all the way to Z….
