Multi-Gigabit wireless fibre backhaul baseband processor
The high-throughput architecture supports, Lattice says, the high sustained data rates required by advanced mobile and wireless access networks; beam-steering technology on phased array antennas reduces installation and maintenance costs in point-to-point networks and enables next-generation mesh networks.
Increasing demand for gigabit IP data to the home is driving demand for fixed wireless broadband access. In addition, in high data density areas, gigabit IP data connectivity is required for metro Wi-Fi and LTE deployments. The 60 GHz band is suitable for these applications due to the large bandwidth available and the propagation characteristics of the band that allow high spectrum reuse, both of which are essential for next-generation wireless network architectures. The chipsets are presented as the first complete solution in the 60 GHz frequency band, using the (acquired by Lattice) SiBEAM technology for increased data throughput and network reliability.
Lattice’s chipsets also support beam-steering technology on phased array antennas. Devices that implement beam-steering require only rough alignment and can be installed quickly without specialised skills. A link can then be established between that node and other nodes in the network without manual intervention, and maintained even under changing environmental conditions or network reorganisation. This significantly reduces installation and maintenance costs.
When used in combination with the Lattice Sil6342 RF transceiver, the SB6541 supports Internet Protocol (IP) data rates of up to 2 Gbps, with a typical throughput of 1 Gbps at a range of up to 300 metres. The device integrates with the RF transceiver via high-speed analogue I/O and a digital control interface. The SB6541 processor can be integrated into any system design through a PCIe interface.
