3G Option


With its comparatively low power consumption and robust techniques for dealing with interference, 3G fixed wireless technology remains a very attractive competitive carrier option. Combined with Internet Protocol, 3G technology can be leveraged to support the voice and data requirements of the most demanding residential and business users. While standards groups continue to finalize mobility 3G standards for roaming and other mobile applications, an extraordinary opportunity now exists to leverage the mature, lower-level 3G physical capabilities for fixed-point
wireless. These open solutions, combined with IP-enabled networking, computing platforms offering varied API support, plus an open services gateway concept, lay the groundwork for a more comprehensive, differentiated set of residential and business services than has ever been attempted.

In sum, 3G fixed wireless technology offers the potential for consumers and telecommuters to get the bandwidth and services of sophisticated private network users — at very reasonable cost. For competitive service providers, 3G can help launch a low cost, comparatively lower-risk service creation platform, and an overthe- air infrastructure based on a software-defined softswitch model that bypasses the expensive Class 5 PSTN switch. With implementations of 3G happening now, next generation fixed wireless represents a great leap forward. Real fixed-point implementations will be possible by mid-2000, and within the next few years, a revolution in competitive residential access could result.
