Evolution of 4G Networks Using Remote Radio Heads
Distributed base stations with remote radio head (RRH) capability assist mobile operators in resolving cost, performance, and efficiency challenges when deploying new base stations that are rapidly moving toward fully-developed 4G networks. Multi-mode radios capable of operating according to GSM, HSPA, LTE, and WiMAX standards and advanced software configurability are key features in the deployment of more flexible and energy-efficient radio networks. This article describes the key market and technology requirements for RRHs and how WiMAX/LTE RRH and intellectual property (IP) core solutions, combined with the latest FPGA technology help enable compact, environmentally-friendly/green, and full-featured applications for mobile network solutions.
