3G Americas Publishes Report on Smart Antennas
The trade association, 3G Americas has announced the publication of an educational report on the topic of smart antenna systems - also known as multiple-input multiple-output (MIMO) technology. Smart antenna, or MIMO, technology is commonly defined as, the use of two or more unique radio signals, in the same radio channel, where each signal carries different digital information, or two or more radio signals that use beam forming, receive combining and spatial multiplexing (SM). Relative to a traditional 1x1 antenna system, a 2x2 MIMO system is expected to deliver significant cell throughput gain. more

10% of base stations using smart antennas
Smart antenna technology is now deployed in one out of every ten base stations in the world, a significant fact for wireless operators seeking a proven technology to expand the capacity and performance of digital wireless networks, according to a new Visant Strategies study. more

Austrian network optimises its 3G network
Since the beginning of this year, Austria's mobilkom austria has been working together exclusively with the software consulting firm, Symena in order to optimise the 3G network in western Austria. The topography of the states Vorarlberg and Tyrol makes operation of the UMTS network difficult, as reflections from mountains causes interference to transmission signals. With "CAPESSO" technology from Symena, the many parameters for each base station can be calculated more effectively, allowing more efficient use of resources. This is of particular benefit in regions with great height differences. "CAPESSO" makes it possible to reduce the amount of base stations and investments which would otherwise be necessary by up to 30%. It also enables considerable increases in actual network capacity and quality. Should this technology prove successful in western Austria, it will be expanded to cover all of Austria, bringing the benefits of "CAPESSO" to eastern Austria as well. more

Symena to develop TD-SCDMA optimization tools
Austria's Symena says that it is committed to developing an optimization tool for the Chinese TD-SCDMA 3G standard. The standard has received a substantial allocation of spectrum in China and several Chinese manufacturers have announced their intention to build equipment for the network. TD-SCDMA requires Smart Antennas on every base station in the network. Smart Antennas in TD-SCDMA are particularly useful in extending the range of base stations in infrastructure poor areas. more

3G network optimisation software leads to fewer base stations
Symena announced results from its UMTS network optimization development project. The purpose of the project is to find techniques for optimizing the performance of UMTS networks. The first objective was to improve performance of readily available conventional Node B and antenna technologies. In the second part, the optimal number of Smart Antennas was incorporated into the infrastructure mix. The results indicate that the performance of conventional networks can be improved by as much as 35%without increased investment in hardware. When the best number of Smart Antennas is deployed in the best locations, performance is improved by 90% with no new sites. The improved performance can be taken as either a reduction in the number of cells required or as increased capacity. more

Smart Antennas will gain from 3G network sharing
As the need to optimize limited wireless spectrum grows, smart antennas will play a critical role in future infrastructure deployments, according to a new study by Allied Business Intelligence (ABI). According to the study, global deployment of smart antenna systems will grow to over 1 million systems by 2006, from under 100,000 this year, representing a compound average annual growth (CAAG) rate of 72%. more
