Sprint/Nextel are deploying an 802.16e compliant mobile wimax network which will reach 100 million Americans by the end of 2008. BT will bid for 2.5GHz RF spectrum in the Ofcom auctions which will take place towards the end of the year 2007. Gaining such spectrum will allow the incumbent to deploy an efficient wimax service and compete with companies such as Vodafone for triple play services. Cable companies are gradually acquiring spectrum and are looking at distributing their content to mobile devices. Greenfield operators are expected to utilize mobile wimax technology in order to secure a 3G/4G market position by attracting consumers with an early new level of service. Clearwire is such a carrier with operations in the United States, Denmark, Belgium, Ireland and in Mexico (via MVSnet).
Equipment manufacturers are becoming increasingly active in mobile wimax. Vendors such as Samsung, Nortel Networks, Alcatel and Nokia-Siemens Networks are all involved in 802.16e projects globally. Motorola have just announced a major deal in Pakistan. Companies that have been heavily involved in operator proprietary broadband wireless implementations such as Alvarion and Proxim are also developing 802.16e compliant platforms. Various chipset providers such as Wavesat, Runcom Technologies and Beceem Communications are developing OFDMA chips and are testing their products for interoperability with solutions from other vendors. Dual mode handsets will be very popular with mobile wimax deployments with GSM/OFDMA and CDMA/OFDMA handsets dominating the market.
But there is confusion. Ericsson believe that by the year 2010 mobile wimax will account for only 5-10% of global broadband wireless revenues and are therefore more focused on broadband cellular technologies. Who is right? Availability of 2.5GHz spectrum is crucial to the success of mobile wimax particularly throughout the western world. In Europe HSPA is dominating the cellular market and this combined with the current unavailability of 2.5GHz spectrum throughout most of the continent is leading to little interest from mobile operators. In the U.S a lot of the 2.5GHz spectrum is owned by Sprint. The carrier will start its deployment by using 10MHz channels to deliver services and could use even larger bandwidths in the future.
Throughout the developed parts of the world technologies such as 3GPP LTE and HSPA are expected to make a huge impact. HSPA operators will begin upgrading to LTE in 2009/2010 with subscribers exceeding 250 million by the year 2015. However as Vodafone's Arun Sarin points out, LTE is still being deliberate by GSM standards bodies, while WiMAX is available NOW.
This report not only discusses mobile wimax but also technologies beyond 3.5G (HSDPA and EV-DO Rev A) such as 3GPP LTE and Ultra Mobile Broadband. Developments in the core network as networks move towards fixed mobile convergence and the IMS are analyzed. The market opportunities of fixed and mobile wimax technologies for each geographical region are looked at in detail. The impact of LTE and UMB on markets is also included in this report.
