The Zyxel VMG3927-B50B Dual-Band Wireless AC/N VDSL2 Gateway supports VDSL2 vectoring of up to profile 35b. VDSL2 vectoring reduces cross-talk to increase broadband access performance, which further enables operators to offer better UHD 4k IPTV services.


Carrier-class WiFi for seamless mobility

Rated as AC2300, the Zyxel VMG3927-B50B delivers speeds of up to 1.7 Gbps* over 5 GHz and 450 Mbps* over 2.4 GHz. For better user experience, the VMG3927-B50B offers dual-band WiFi with performance-boosting features such as Multi-User MIMO (MU-MIMO) and Beamforming for simultaneous, lag-free streaming and gaming experiences. In addition, its ability to create multiple WiFi networks with up to 4 SSIDs helps operators to easily create individual WLAN networks for video, data and guests.


Connected, anywhere at home

Zyxel’s Multy Pro mobile app is a simple, effective utility to help customers setup, adjust and check their home networks. Combining network discovery, easy setup and diagnostics for devices connected to the home network, it also allows service providers to effectively analyze network issues for customers if needed. The Zyxel Multy Pro app gives the best experience while reducing home support costs and service calls by relieving customers’ troubles remotely.


The triple-play powerhouse

The Zyxel VMG3927-B50B is built with sophisticated QoS and multicast traffic shaping features like IGMP v1/2/3 snooping and VLAN capabilities for premium video delivery services. To wireless IPTV operators, its built-in 4x4, 802.11ac chip is the top choice.


TR-069 remote management with TR-181 issue-2 support

The Zyxel VMG3927-B50B supports TR-69 that simplifies remote configuration, upgrade and management and therefore improves cost effectiveness and customer satisfaction. Additional support to the latest TR-181 issue-2 data model also enhances service providers’ visibility on subscriber LAN networks for improved customer assistance.
