Wireless data usage has doubled every year since the introduction smart phone driving changes in the wireless standards (3GPP, CPRI) and network architecture- both mobile network and mobile backhaul.
Mobile cellular infrastructure has evolved from the traditional analog circuited switched system to today's 4G packet switched digital system based on orthogonal frequency-division multiple access (OFDMA) and multiple-input multiple-output (MIMO). During this time the download rates have increased from 10’s of Kbps to 10’s Mbps which corresponding changes to the physical layer and upper layers of the network.
The increasing data rate has forced dramatic architectural changes including macro, micro and Pico cells to form a Heterogeneous Network (HETNET).
Today LTE-Advanced features such as carrier aggregation, CoMP and eICIC are being incorporated in LTE networks to boost data capacity and concepts like Centralized RAN ( C-RAN) and 5G are being researched to boost peak download to the Gbps range.
These dynamic requirements have driven wireless infrastructure operators to embrace the flexibility and future proofing offered by FPGA technology. Altera provides a complete portfolio of high-performance, low-cost FPGAs delivering the processing bandwidth and flexibility for wireless including a complete ecosystem with intellectual property (IP), advanced signal processing techniques and reference designs.
