4G LTE Mobility and Dual-SIM 
With 4G/LTE-based internet connection (4G/LTE module and dual-SIM embedded), users can access the internet while sitting on anywhere. The Dual-SIM provides failover feature to keep internet connectivity if primary SIM loses connectivity. 

Automatic Failover/Failback between 4G/LTE and Gigabit EWAN 
Uniquely embedded with 4G/LTE and Gigabit EWAN interfaces, BiPAC 4520VAOZ ensures a seamless internet connectivity by featuring superior Failover/Failback functionality between 4G/LTE and EWAN. Either wired or wireless connection can be set up as primary or backup WAN port. When the main WAN interface fails, the secondary WAN interface will automatically back up the connection to ensure an always-on connectivity. 

Dual-Band Wireless Mobility and Security 
With an integrated dual-band wireless access point, BiPAC 4520VAOZ runs both 2.4GHz and 5GHz simultaneously that the combined throughput can reach 1.2Gbps (867Mbps at 5GHz, 300Mbps at 2.4GHz). Multiple SSIDs with Client Isolation to enhance the level of transmission security and access control over the Wireless LAN. The network manager can assign different policies and functions for each SSID, increasing the flexibility and efficiency of the network infrastructure. 

Secured VPN connection 
Supporting comprehensive and robust VPN (Virtual Private Network) protocols including IPSec, OpenVPN, GRE, PPTP, L2TP, BiPAC 4520VAOZ allows users can establish private and encrypted data transmission tunnels over the public Internet between headquarter and branch offices. With a built-in DES/3DES VPN accelerator, BiPAC 4520VAOZ dramatically enhances IPSec VPN performance.

VoIP Supplemental Services
