The Economic argument for AAS for WiMAX

In my last post, I discussed the benefits of Advanced Antenna Subsystem (AAS) techniques and the RF advances they enable – MIMO, Beamforming, and MIMO+BF in terms of technology. Now I’d like to look at the same technologies, but from the standpoint of service provider economics and the SP business case.

MIMO alone

MIMO-A (space time coding) is for robustness while mobile, in a fading environment. The base station sends all the same data twice, once from each… Continue

Motorola, Alcatel-Lucent, Alvarion, and Huawei claimed to be top Mobile WiMAX vendors (Infonetics Research)

Infonetics Research recently surveyed carriers to determine the "top vendors" in the mobile WiMAX equipment market. The carriers chose Motorola, Alcatel-Lucent, Alvarion, and Huawei as the top four vendors. Nine additional vendors received votes for top WiMAX equipment vendor from a smaller number of carriers surveyed.

The Infonetics report: Perception Is Everything: WiMAX Vendor Leadership Service Provider Survey shows that the top 4 vendors are front-runners in… Continue

Coming in February.....

February is MWC month, and an all expenses paid trip to Barcelona, pickpocket capital of the world after Florence, Italy (a.k.a. Firenza). I will be there, working 9 to 9 every day. Here's what I expect:

1) LTE everywhere! Not products, but prototypes

2) Smaller crowds, fewer booths - the recession bites

3) A valiant effort from WiMAX to steal a share of the Mobile Internet spotlight

4) An equally valiant effort from Ericsson and the GSMA to get it… Continue

Advanced Antenna System (AAS) Techniques for WiMAX

There is a lot of disinformation being spread in the WiMAX community about my subject of today, beamforming, and about other advanced RF technologies such as MIMO. Some vendors try to portray them as opposite, competing technologies. I see them as complementary. Someone has to set the record straight…..

The WiMAX Forum identified and standardized two “Advanced Antenna System” (AAS) technologies, and included them in the so-called “Wave 2” profiles for Mobile WiMAX. These were MIMO… Continue

Where are the WiMAX MIDs hiding?

We noted the absence of major vendor MID announcements at CES. Based on our Jan 08 IEEE ComSoc meeting presentation (Internet in Your Pocket presentation by Rama Shukla of Intel), we were expecting a raft of WiMAX capable MIDs to be announced at CES. We were disappointed.

While not having attended CES, we did see blog posts about Yukyung’s Viliv "X70 AtoM Communications MID." For info please visit:

The company is based in… Continue

Clearwire Debuts CLEAR service in Portland, OR

Please see:

Several industry analysts have cautioned that Clearwire, despite receiving $3.2 billion in capital investments from Intel, Google, Comcast and others, may not have enough capital to proceed with an overly ambitious rollout plan and may have to significantly scale back its deployment plans. Do you think they will have enough money to proceed with 7… Continue

Narrowbanding WiMAX in India

Narrowbanding WiMAX

5 Jan 2009

It appears that the Foggy weather in Delhi extends to much more than just atmosphere, certainly to the Foggy Policies and to the ministries of Telecom and Finance. The Ministry of Finance has recommended the doubling of the reserve prices to $ 8 Billion for 3G and $ 4 Billion for WiMAX. Even though such events are quite common to policy watchers and hardly ruffle any feathers, this one takes the cake for a number of reasons.

In principle we… Continue

WiMAX in Latin America

There are a few small scale deployments of WiMAX already in Latin America, but spectrum remains an issue, especially in the biggest country in South America, Brasil ("Brazil" to English speakers).

I just spent much of this week south of the equator in Rio de Janeiro, by the famous beach, where it is now late spring. Don't feel sorry for me.......

But I was there to work, not play, at the WiMAX Forum's Latin America Congress. The spectrum regulator, Anatel, is struggling… Continue

WCAI Conference: Market status and outlook for Fixed and Mobile Broadband Wireless Access

Editors Note: The WCAI organization is composed primarilly of WiMAX supporters, so the overwhelming content at their conferences is devoted to evangelize and promote WiMAX in all forms. LTE is only discussed in the context of being synergistic with WiMAX rather than being competitive. Therefore, the majority of this report is focused on WiMAX. We'll try to capture the highlights of several marketing and business related sessions.

Industry Keynote
: Dr.… Continue

The Importance of Being Earnest

Ok, so the real subject is being certified. As in "certified by the WiMAX Forum", or at least, its surrogate, AT4. Certification is going to be a must, but not for the reason that most people think.

The actual certification test, which is performed using a document issued the WiMAX Forum's Certification Working Group (or GWG), tests interoperability between a base station, and a different vendor's subscriber modem or CPE device, and then repeats the same tests with another CPE from… Continue

LTE Field Trials Move Forward, while timing of global WiMAX deployments is uncertain

Ericsson maxes out speeds in LTE field tests

In field trials of Long Term Evolution (LTE), the ITU based "4G" mobile technology, Ericsson has surpassed speeds of 100 Mbps, the company said. Using four transmit streams (the maximum number supported in the LTE standard), four receive antennas and bandwidth of 10 MHz, the measured peak rates exceeded 130M bps. This translates into approximately 260M bps, given the maximum bandwidth of 20 MHz, according to an article in Ericsson Review.… Continue
