Recession dividing LTE and WiMax

Source: ZDNet Asia
The global economic situation may widen the rift between LTE (long term evolution) and mobile WiMax adoption between mature and emerging markets, according to Ovum.

The analyst firm said in its latest report, the recession is expected to slow revenue growth for operators in the short term, although the volume of connections will keep rising. This will lead to lower ARPU (average revenue per user), in turn driving the uptake of LTE in mature markets, as telcos look to upgrade to next-generation networks to capture data revenues, said Ovum.

Nokia Siemens Networks has shed light on what it plans to do with the Nortel Networks Ltd. Long Term Evolution (LTE) assets.

NSN's head of radio access, Marc Rouanne, tells Unstrung that the vendor plans to incorporate Nortel's LTE algorithms and software into its own flagship Flexi base station platform. NSN will not maintain or have to integrate two separate LTE base station product platforms.

Nortel 4G patents may not be worth that much

Embattled Canadian vendor Nortel may have held on to some of its key LTE patents when it flogged much of its mobile business to Nokia Siemens Networks last month, but there is some debate as to whether that IPR will be the nice little earner Nortel hopes.

Nortel's LTE Patent Goldmine

There's a good reason why Nortel Networks Ltd. seems keen to hold on to its LTE (Long Term Evolution) access intellectual property and not flog it to Nokia Siemens Networks as part of its wireless asset fire sale: Those patents are worth an absolute fortune!

That, at least, is the view of JP.MorganChase analyst Ehud Gelblum, who issued a research note Monday stating that Nortel's LTE patents could generate royalty revenues of hundreds of millions of dollars, possibly even as much as $2.9 billion.

Voice Over LTE & the 'IMS Gap'

Mobile voice is a phenomenon. Together with SMS, it accounts for 85 percent of the world's $800 billion per year mobile services market, according to the latest estimates in the Global Mobile Data Forecast from Pyramid Research.

But for operators evaluating the investment case for Long Term Evolution (LTE) mobile broadband networks, there's concern that this next-generation technology doesn't yet adequately support their most critical and profitable circuit-switch applications: voice and SMS.
