ABI Research Forecasts LTE Flat Architecture and SIP Capability to Dominate Mobile Markets After 2011.

LONDON -- UMTS Long Term Evolution (LTE) will dominate the world's mobile infrastructure markets after 2011, according to a recent study from ABI Research. While LTE will encounter competition from other mobile broadband technologies, its supporters point to its flat architecture, low latency, and IP NGN (Next-Generation Network) capability to provide a range of SIP (Session Initiation Protocol) services.

LTE brings to the market 25 years of operating experience using TDM and CDMA technology. Vendors and operators aim to use that experience, combined with OFDM and other techniques, to provide the best of both worlds. This also takes the industry from the current two-network approach of circuit-switching for voice and packet-switching for data to a single IP network for both services.

"LTE faces competition from other broadband wireless technologies and it will need to demonstrate clear technical and economic advantages to convince network operators," says ABI Research analyst Ian Cox. "The mobile variant of WiMAX will start to appear in 2007 as the WiMAX Forum Certification program ramps up. The industry is also working on HSPA+, which could offer the same performance in a 5 MHz bandwidth. Without additional spectrum, operators could face a difficult choice."

Cox adds, "LTE is the NGN for the mobile industry and is being standardized by 3GPP with the full support of operators via the NGMN Group."

Long Term Evolution of 3G technologies is about to benefit from Release-8 of the 3GPP standard, planned for 3Q 2007. The potential rewards of LTE are simplicity of operation, a "flat" architecture offering low latency, and spectrum flexibility. Backwards-compatibility and roaming with 2G and 3G networks are added bonuses, along with lower power consumption and improved performance. LTE could potentially unite the W-CDMA and CDMA communities because of its spectral flexibility.

"For users," says Cox, "LTE will enable broadband services -- including VoIP -- to be offered over SIP-enabled networks. Each service will be IP-based, offering high data rates and low latency, with online gaming becoming a reality along with mobile network data speeds comparable to those of fixed networks. For vendors, LTE will allow the development of a new market to replace declining 3G revenues."
