Prague, Czech Republic (PRWEB) November 2, 2005
The International 450 Association held its 4th Plenary Meeting last week in conjunction with the 450 Digitalization Conference organized by Informa. Both of these events demonstrated the growing success of mobile cellular and fixed wireless networks operating in the 450 MHz band using CDMA2000® (also known as CDMA450).
Over the past 12 months more than 15 new networks have been brought into commercial service and licenses to operate CDMA450 networks have been issued in more than 10 countries bringing the total number of CDMA450 operations to 30. Growth is particularly strong in Asia and South America, and CDMA450 networks are also being established in Africa and the Middle East.
CDMA450 is a very spectrally efficient technology which allows the introduction of high capacity voice and fast data mobile services in frequency spectrum less than 1.8 MHz. Using the excellent propagation properties of this frequency band CDMA450 networks can cover large areas with a minimum of base stations giving a relatively low capital outlay when building and expanding a CDMA 450 network. This allows truly affordable high capacity voice and high speed data services to be delivered to both urban and rural communities for the first time.
The 450 Digitalization Conference showed the diversity of services which CDMA450 can offer. From low cost voice, to the provision of universal high speed data services, delivering data speeds of up to 2.4 Mbits/second using CDMA2000® EV-DO. The cost of both voice and data terminals (fixed and mobile) are falling due to the rapid increase in subscriber numbers and the choice of terminals are increasing with more manufacturers bringing CDMA450 products to market.
At the exhibition associated with the Conference a number of manufacturers exhibited CDMA450 products. Four major manufacturers are currently selling infrastructure products for CDMA450 networks together with a number of other manufacturers selling individual network components. Another 7 companies are supplying Mobile, Data and Fixed Wireless Access terminal products for CDMA450.
The next big step for the evolution for CDMA450 will be the introduction of CDMA 2000 EV-DO rev A which will result in the increase in downlink and uplink data speeds up to 3.1 Mbits/second and 1.8 Mbits/second respectively, which will give the option of using Voice over IP (VoIP). The introduction of CDMA 2000 EV-DO Rev A is planned for the second half of 2006 and will enable remote subscribers to receive even more enhanced broadband data services in remote locations or whilst on the move.
Note for editors:
The International 450 Association (IA 450) was formed 4 years ago to promote the use of the analogue and digital technologies in the 400 to 500 MHz band. Currently the IA 450 has 35 members including 17 operator members and 18 industrial members. The IA 450 represents the interests of mobile operators using the 450 MHz band and suppliers of 450 MHz systems and terminals. The IA 450 membership includes operators in Scandinavia, Central & Eastern Europe, Asia and Africa.
The IA 450 promotes the use of CDMA2000® in the 450MHz band, and supports industry standards to advance the deployment of the technology. The IA 450 provides guidance and leadership to operators interested in deploying this technology through the extension of the results and benefits of actual member experiences and real life results and successes, to all global players. More information about the IA 450 can be found on the IA 450 web site at http://www.450world.org.
