Verso and Navini rise to VoIP over WiMAX challenge
Voice is probably the only real 'killer application' that has ever been seen in wireless, and this has created one of the fundamental challenges for the industry - as networks evolve to support new data and media oriented functionality, how do operators simultaneously retain a profitable voice operation, even while introducing packet-based networks that have not been designed for voice? For operators with GSM networks, the answer, at least for the medium term, is likely to be hand-off between data-focused IP systems and super-efficient GSM-based voice networks. But maintaining ageing legacy networks and dual-mode devices will not be a strong option for the longer term, hence the huge investment being made in running VoIP effectively on all kinds of wireless systems, including CDMA and LTE.

Microsoft leads internet industry bid to dominate vacated TV spectrum
It is clear that the mobile internet, once it becomes truly workable, will become a cornerstone of business and communications.

Advances in technology, particularly in the OFDM-based systems like WiMAX, has narrowed the performance gap and added the non-line of sight element that supports nomadic usage, the one area where wireline options, of course, cannot compete. This has placed huge expectations on broadband wireless networks, WiMAX in particular, to deliver a full fixed/mobile convergence platform that will combine, at least in the next generation of the technologies, DSL or fiber grade fixed delivery plus full mobility.\u003c/span\> \u003c/p\> \u003cp\>\u003cspan\>\u003ca href\u003d\"http://r.vresp.com/?Trendsmedia/c427fd827f/901356/404f44ff39/c97cd5e\" target\u003d\"_blank\" onclick\u003d\"return top.js.OpenExtLink(window,event,this)\"\>Sprint and Clearwire jitters show danger of short term thinking in wireless\u003c/a\>\u003c/span\>\u003cbr\> \n \u003cspan\>Outside Korea , Sprint Nextel and Clearwire have been the biggest early flag wavers for WiMAX in the operator community, and almost inevitably, the over-excitement surrounding such early stage projects was bound to wear off somewhat as the realities of commercial deployment and return on investment pressures take over from the initial euphoria. So Sprint is rumored to be facing delays already to its aggressive roll-out schedule, and possibly seeking additional vendor support (for which read, flexible financing too) amid its current financial setbacks. And Clearwire, while launching its Nasdaq IPO last week, failed to make the spectacular impact some had predicted.",1]

IBM's promotion of metrozone WiMAX leads to Texas deal
IBM has shown an increasingly keen interest, over the past few years, in the potential for its integration business in the metrozone market, and now it is set to take advantage of this sector's evolution from focusing on best effort, socially oriented networks, to providing carrier class services.ption
