5G Base Stations

Massive MIMO antennas, millimeter-wave RF front-ends, baseband processing units, and power management for next-generation mobile networks supporting enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive IoT connectivity.

Wireless Infrastructure

Small cell base stations, distributed antenna systems (DAS), WiFi 6/6E access points, and private LTE/5G networks requiring high-efficiency power amplifiers, low-noise amplifiers, and multi-band transceivers for seamless coverage.

Core Network Equipment

Routers, switches, and SDN/NFV platforms for carrier backhaul networks, featuring high-speed Ethernet controllers, packet processors, network processors, and merchant silicon for terabit-scale data center interconnect (DCI) and metro/long-haul transport.

IoT & M2M Connectivity

NB-IoT, LTE-M, LoRaWAN, and satellite IoT modules for massive machine-type communications in smart cities, industrial automation, and asset tracking applications requiring ultra-low power consumption and extended coverage range.
