ALT4800
CAT-12 Ultra-High Speed Broadband Backhaul Chipset
Altair’s ALT4800 features 8 RX antennas and is ideal for very high-speed, high-capacity access applications including fixed broadband Wi-Fi routers and gateways, as well as small-cells with a high-speed backhaul link.The ALT4800 features an LTE modem SoC that supports CAT-12 throughputs of 600Mbps downlink and 150 Mbps uplink, Release 11 features, and a high performance MCU subsystem.The chipset incorporates state-of-the-art technologies such as MIMO decoding of up to 8×4 using Altair’s proprietary INCA™ interference cancellation, doubling LTE cell throughput. ALT4800 supports up to 3 carrier aggregation, and 4×4 MIMO decoding and beamforming in the uplink.The ALT4800 modem implements 8x 20 MHz receive chains and 4x 20 MHz transmit chains.In addition, the ALT4800 integrates an embedded network processor with a Linux operating system intended for OEM application development.
