With each of the top three mobile infrastructure OEMs introducing multi-standard radio base stations, the wireless industry is looking towards a future where base stations can handle multiple air interface standards in a single, highly efficient module. Ericsson and Huawei have launched their MSR-BTS product lines to support easy upgrade from HSPA to LTE. In addition, Nokia Siemens Networks recently introduced their latest generation Flexi Multiradio BTS that can support GSM, HSPA, I-HSPA and LTE in a single box. Mobile operators will rapidly adopt MSR-BTS technology over the next five years for 3G and 4G networks according to the latest report from EJL Wireless Research titled “Multi-Standard, Multi-Mode, Multi-RAT Base Stations Analysis and

“The flexibility of a software-defined radio (SDR) is here and now. The traditional single standard base station architecture is transforming to MSR-BTS technology as the investment and technical needs of the mobile operators shift. We have completed a detailed technical analysis, highlighting opportunities for suppliers to benefit from this migration,” said founder and President, Earl Lum. “The acceleration of the wireless industry towards 3G networks and the introduction of 4G networks by 2010 is causing investment concerns for mobile operators who need to future proof their networks. One solution is the MSR-BTS. MSR-BTS technology will represent over 50% of total base station shipments by 2013,” said Lum.

Nokia Siemens Networks, Ericsson, and Huawei --- the top 3 suppliers of wireless infrastructure --- are all heading in the same direction with their products. All three have introduced new base station products which support the variable bandwidth for LTE, as well as multiple variations of WCDMA/HSPA technology. The flexibility that is inherent in supporting the latest standards is now available as “future proofing” for mobile operators. While these products are coming onto the market, there are also regulatory changes underway which will enable the new base station products to be applied to legacy standards such as GSM and EDGE. Therefore, over time we can expect legacy GSM base transceiver stations to be replaced by multi-standard radio base stations (MSR BTS). It will not be unusual in the future for a cell site to handle two or three frequency bands and four air interface standards simultaneously. Upgrades to the radio access network will become much simpler, with software upgrades handling most of an operator’s requirements. Radio hardware upgrades will take place in the case of adding MIMO transmitters or new frequency bands, but not in the case of capacity upgrades. Overall, the strong trends toward MSR base stations and remote radio heads will dramatically change the infrastructure ecosystem. We can expect virtually all of the LTE eNodeB units deployed to use software-definable radios, even when used in an LTE-only application. Most W-CDMA nodeB hardware will also use SDR technology to allow for software-upgrade to LTE over time. As remote radio head topologies are used (even if the RRH is mounted at the base of a tower), the modular form of an RF unit with a fiber interface to the system module will become the standard for the wireless industry.
