[Wireless] Sprint nosedives! Then, WiMAX???

Sprint-Nextel lost more than 20 percent of their stocks value after it annnounced fourth-quarter earning (or loss?) yesterday. The shares of its WiMAX partner - Clearwire, also dropped more than 10 percent in two days.

Now in market, most wireless firms are betting on 3G wireless networks. Even the new handset player, Apple, is going to launch a 3G-capable iPhone this year. Although 3G system was not deployed as fast as it was expected initially, it finally occupies a part of the wireless market and becomes bigger in years. Although WiMAX is newly designed with more advanced technologies, it may have a disadvantage than 3G in time-to-market.

So, who will drive wireless to the MAX? LTE or WiMAX? I bet nobody can answer this. What we know is: Sprint plans to launch commerical WiMAX service in Q2 2008. Ericsson plans to invest 1.5 billion dollars into next generation wireless systems (LTE or 4G) in three years.

But I'll say, no matter it's LTE, WiMAX or 4G, the winner is always OFDM+MIMO. :-)

I've been browsing on-line more than 3 hours today, but I never discovered any interesting article like yours.
It's lovely worth sufficient for me. In my opinion, if all
webmasters and bloggers made excellent content material as you
did, the internet will probably be a lot more useful than ever before.
