Overview
Description:
GRG-4277u is a highly integrated GPON access device. It offers high performance Data, Voice and Video services for individual users, SOHO (small office or family office), small businesses, etc.
GRG-4277u complies with the ITU-T G.984 standard, provides 2.488 Gbps downlink and 1.244 Gbps uplink on the network side, and provides four high speed GE ports, one FXS port for internet calling, dual band Wi-Fi 6 (2T2R 802.11ax@2.4GHz and 2T2R 802.11ax@5GHz). The two wireless bands are separated in two dedicated Wi-Fi networks, supporting more end-user devices while reducing signal interference. Furthermore, there are two USB2.0 host interfaces on the user side.
Support of the Wi-Fi Alliance EasyMesh standard secures seamless integration for future Mesh applications.
