Lattice and Affarii Technologies Offer Complete Remote Radio Head Hardware Solution for Wireless Infrastructure

Wireless operators are increasingly challenged to support a diverse set of technology standards and increased customer bandwidth driven by growth in data services. At the same time, they are pressured to lower capital and operational costs of the networks that will deliver both new and existing services. This has resulted in the move toward a Distributed Base Station Architecture where multiple Remote Radio Heads (RRH) mounted on antennas are connected to a single base station unit using high-speed optical links. This lowers deployment costs while allowing for flexible upgrades. Traditionally, near antenna logic for MIMO-based RRH systems has been implemented in high-end, premium FPGAs. The high cost and power dissipation of these high-end FPGAs has forced vendors to sacrifice design flexibility and attempt expensive ASIC conversions.

Lattice and Affarii Technologies, Ltd. have developed a complete 3G/4G-based RRH solution for wireless infrastructure designers. This is the first time that a full RRH solution has been made available using the low-power, low-cost LatticeECP3 FPGAs that allow low-power RRHs to be deployed without sacrificing flexibility or performance.
