San Jose, Calif. - Samplify Systems, Inc., today announces Prism IQ compression technology optimized for wireless infrastructure applications using the Common Public Radio Interface (CPRI) standard.'Prism IQ reduces the fiber optic bandwidth requirements for wireless base stations by over 2:1, reducing the bit rate by half and saving mobile operators significant CAPEX and ongoing OPEX as they migrate to fourth generation technologies.
"With 4G, mobile operators are facing expensive upgrades to their fiber optic infrastructure at tower and building sites for the deployment of remote radio units," says Al Wegener, Founder, Chairman and CTO of Samplify Systems. "By working with our wireless OEM customers, Samplify has proven better than 2:1 reduction in this fiber optic capacity while providing a test equipment level of signal quality."
First introduced for 3rd generation systems, CPRI is a leading standard for carrying baseband (I/Q) data across fiber optic connections between radio units at the top, and baseband units at the bottom of the base station tower. For 4G, the fiber optic capacity increases from less than 3 Gbps to up to 6 Gbps, or even multiple 6 Gbps links in the case of TD-LTE within China.
The Prism IQ algorithm is optimized for complex (I/Q) baseband signals, providing up to 4 dB improvement in error vector magnitude (EVM) performance than Samplify's current algorithm. A new DelayTrak mode ensures low latency across high speed SERDES links while enabling system architects to design to a target compression ratio. Multi-channel support lowers latency for multiple low bandwidth signals - a single Prism IQ compression core can operate on interleaved samples from multiple carriers, effectively increasing the sample rate thereby lowering the latency due to pipelining.
Samplify is working closely with the wireless infrastructure ecosystem to develop the next generation of discrete and FPGA-based implementations, leveraging its Prism IQ compression technology. Samplify recently partnered with IDT to develop signal-chain solutions, which require the high-speed transmission of large quantities of data from the top of the tower to the baseband processors at the bottom. Currently, this is being done using discrete devices and FPGAs.
Samplify is exhibiting at the Embedded Systems Conference, Silicon Valley, Booth 3028, from April 26-29th at the McEnery Convention Center in San Jose, CA.
