Global Interoperability of Mobile WiMAX - Let's Stick Together
Let’s start this blog by discussing global interoperability of Mobile WiMax - Let’s stick together. I have enclosed a jpeg photo of what I mean. It is my opinion that in order for Mobile WiMax to gain popularity, the three largest mobile subscriber capacity countries in the world today, China, the USA and India all would have to provide global interoperability in the same frequency range. Sprint-Nextel is specifically working with ZTE in order to influence the Chinese infrastructure equipment vendors to adopt a Mobile WiMax standard in 2.5GHz frequency range.
Intel is working to adopt 2.5GHz frequency range
in China and India. China and India stand to be the largest markets to deploy
broadband and Mobile WiMax in the coming years, however, currently South Korea
and Taiwan are the major infrastructure equipment manufacturers producing Mobile
WiMax (and WiBro) equipment. Both are eyeing China’s huge potential market
opportunities, not to mention the USA. We have a triangular interoperability
scheme between each country’s frequency resources.
Intel has set up testing facilities in Taiwan and South Korea for Mobile WiMax.
Taiwan’s equipment vendors will influence sales of WiMax gear to China as will
Intel, pushing for in country adoption. Samsung WiBro technology will benefit by
undertaking the production of Wibro base stations in Hubei province. China will
eventually adopt this technology as their own local technology firms get
involved in more IP creation and production of WiMax technology, which they will
undoubtedly do. India has started to deploy Fixed WiMax in 3.4GHz frequency
range, however, just like China, they will have to take existing frequencies
allocated for satellite usage and reallocate it for Mobile WiMax.
India’s TRAI authority is very close to realizing
the value of doing this and I expect they will do it very soon after all these
early fixed deployments gain momentum (Bharti, VSNL, BSNL are in the process of
deploying Fixed WiMax now), then they will conclude Mobile WiMax is right for
India. Only in this way can Mobile WiMax expect to gain majority success
globally (just like the GSM standard). You can not build a global standard for
Mobile WiMax if the two largest emerging markets in the World don’t agree on the
2.5GHz global interoperability frequency range with the largest developed
country (USA) already rolling out Mobile WiMax in 2.5GHz range (for
interoperability of device usage around the World)..
