Mobile WiMax Marks Milestone

Mobile WiMax hit a milestone when the WiMAX Forum announced the first products to receive official certification, which will ensure interoperability between the mobile broadband equipment. (See Mobile WiMax Gets Certified.)

At the WiMAX Forum Congress Asia conference in Singapore, the Forum revealed the first eight products to get the "certified seal of approval." Four base stations and four subscriber units for 2.3 GHz were approved from Posdata Co. Ltd. , Runcom Technologies Ltd. , Samsung Electronics Co. Ltd. (Korea: SEC), and Sequans Communications . (See Sequans Gets Certified.)

The Forum said it expected to announce certified mobile WiMax products in the 2.5 GHz frequency band "in the coming months." Overall, the Forum said it would certify more than 100 products by the end of this year. Certification of 2.5 GHz equipment will be especially important to Sprint Corp. (NYSE: S) and its partners, since the operator is using that bandwidth for its nationwide network in the U.S. (See Sprint Quiet on WiMax Launch Date.)

"With the first group of Mobile WiMAX certified products now available, we have delivered on our promise to ensure that WiMAX products are interoperable," said WiMax Forum president Ron Resnick in a statement.

In February, the Forum said that 28 products for 2.3 GHz and 2.5 GHz had been submitted for certification testing. (See WiMax Forum Updates on Progress.)

The newly certified products include Posdata's FLYVO USB modem and base station; Runcom's stand-alone base station unit and user terminal; Samsung's SPI-2110 base station and PCMCIA card; and Sequan's subscriber station and base station reference designs.

The tests took place at AT4 Wireless Inc. labs in Malaga, Spain, with input from members of the Telecommunications Technology Association (TTA) 's IT testing and certification lab from Seoul, Korea. (See AT4 Tests With Anite, AT4, Sequans Team, and WiMAX Forum Picks Testers.)

re: Mobile WiMax Marks Milestone So 2.3GHz WiBro has been deployed by KT (and nowhere else to my knowledge) for quite a long time using Samsung,Posdata,Runcom stuff.

What is the story here?

Or empty PR from WiMAX Forum?

re: Mobile WiMax Marks Milestone To me, there's some news here:

-- Still no certified 2.5 GHz (See http://staging.unstrung.com/bl....

-- Its fine for KT to run that stuff but as WiMax/Bro market gets bigger (maybe) interoperability gets more important, especially if users are interested in roaming between networks.

re: Mobile WiMax Marks Milestone Freetoair said:...And yes the Certification of 2.3 profile is fine but no big story. It has been certified in the field with these vendors for quite awhile. Is anyone else using 2.3GHz WiBro? Or planning to? I thought WiMAX was the global standard? My point - this was/is a "political" milestone not a "technical" milestone.


You are both missing the important point.

This is *WiMAX Forum* certification - the first time that has happened.

Freetoair - WiBRO was *not* "certified in the field" as until this there was no certification.

You talk of WiBRO as though it were something different from WiMAX; that has not been true for sometime but this categorically lays that idea to rest: this is WiMAX and WiMAX is the global standard (including Korea).

Other people do use 2.3GHz, but that isn't too important: the difference between WiMAX at 2.3 and WiMAX at 2.5 is not huge (does anyone care about GSM at 1.8 vs 1.9GHz?)

All of these vendors are the same ones selling the same (now certified) WiMAX kit internationally.

re: Mobile WiMax Marks Milestone This is *WiMAX Forum* certification - the first time that has happened.

>> so what? they ran the test cases...

Freetoair - WiBRO was *not* "certified in the field" as until this there was no certification.

>> I meant "essentially", KT & vendors did not wait for WF Certification, the profile matches what they built/deployed - not the other way around (i.e. IEEE 802.16e, WF profile etc.). Furthermore at the end of the day, the field experience is a much better test that the lab certification.

You talk of WiBRO as though it were something different from WiMAX; that has not been true for sometime but this categorically lays that idea to rest: this is WiMAX and WiMAX is the global standard (including Korea).

>> Well WF adopted the "profile" under thier umbrella...but what is in the field in Korea is WiBro and not WiMAX. There are differences...but fine call it what you will...just Marketing positioning - not Technical fact.

Other people do use 2.3GHz, but that isn't too important: the difference between WiMAX at 2.3 and WiMAX at 2.5 is not huge (does anyone care about GSM at 1.8 vs 1.9GHz?)

>> and your point is???

All of these vendors are the same ones selling the same (now certified) WiMAX kit internationally.

>> So the kit tested was technically the same as it would be if it were 2.5GHz? You are saying I could take that equipment certified and simply change the RF to 2.5GHz and it would meet IEEE 802.16e standard? Maybe I do not know for sure what they used for testing...but if it was what is in the field with KT now - I do not think so.

>> Anyway my bottom line is that this is all "Marketing and Political Positioning". Move on to 2.5GHz Certification and then there may be some news.
