US WiMAX player Clearwire has announced that it has raised $715.5m from its shareholders to fund its deployment of 4G LTE technology. The firm said it will use the funds for operations and maintenance as well as new network construction.
Jayhun Mollazade was a man with an idea. As an Azerbaijani citizen living in the USA he saw an opportunity to dramatically improve the ageing and archaic soviet telecoms infrastructure of the former Soviet state. Over the past five years, Azerbaijan has put an emphasis on developing its ICT sector and as a result the country now has three mobile carriers along with several ISPs offering ADSL based fixed-line internet connectivity. While the broadband market was growing by 30-40 per cent each year only one of the local carriers was offering 3G services and Mollazade and his partners saw that there was a real opportunity to offer high speed wireless data services.

We can’t see it, touch it, or hear it, but radio spectrum is central to our lives. It is the essential raw material for all mobile services and, like many raw materials, it is a finite and therefore extremely valuable resource for which demand is increasing all the time.

Much has been said and written of late about congestion in mobile data networks, a subject brought to the fore by the introduction of the iPhone and its subsequent clones. Indeed, the problem has precipitated a whole new sub-section of the OSS/BSS industry devoted specifically to identifying and controlling wireless broadband data traffic. There is potentially an equally serious problem however in the form of congestion on the signaling channel caused by ‘chatty’ applications and the signaling requirements of increasingly complex services running on smartphones.
