Alcatel Lucent has announced the introduction of a new radio module, based on software defined radio (SDR) technology, that gives mobile service providers the flexibility to support any mix of GSM, W CDMA HSPA and LTE services simultaneously.
The new converged radio module, called the MC-TRX, is a key building block of Alcatel-Lucent's Converged RAN (radio access network) portfolio. This product is available for operators worldwide and has already been selected by (unnamed) tier 1 mobile service providers.
"With multiple spectrum options and technology options before them, operators need to make CapEx containment a priority as they plan their network launches," said Peter Jarich, Service Director with Current Analysis. "To that end, network infrastructure that supports spectrum and technology evolutions along with the carrier capacity to execute on these evolutions is a must."
This new radio module enables the mobile network operators to "re-farm" their 900 or 1800 MHz spectrum -- currently used to provide GSM services -- by introducing W-CDMA/HSPA+ or LTE services through simple software activation. This process can be managed dynamically -- if the majority of wireless subscribers on the network are using GSM, the module will be configured in GSM mode. As more subscribers move toward W-CDMA or LTE the module can shift the relative mix of technology to allocate more power and carriers to W-CDMA or LTE.
"Clearly, the success wireless network operators have had with data services is creating a requirement that they continually increase user throughput, and our latest innovations are helping them do exactly that," said Wim Sweldens, president of Alcatel-Lucent's Wireless Networks Product activities. "The new converged radio module lets customers evolve networks at their own pace while optimizing use of available spectrum - by introducing more efficient technologies -- minimizing the total cost of ownership. Just as importantly, it enables operators to prepare for the kind of bandwidth demands generated by the growth of multimedia services, supported on a variety of all-IP networks."
