What is the difference between MM2211-NG and MM2211-DZ?

• The MM2211-NG (along with MM2225-NG and MM2211-EXT) are the ‘Next Generation’ Metro Broadband Gateway to extend the Metro Wi-Fi signals for PC users, Metro Hotspots, and any other applications that require extension of the wireless coverage. The MM2211-NG has all of the features that the first generation MM2211-DZ provides with many other key features. Some of the new features are listed below:
  • Dual Zone with Layer3 Bridge Mode – In addition to the existing routed mode, Dual Zone can now operates in Layer 3 Bridge Mode. The user can configure the appropriate mode from the WebUI.
  • Layer 3 Bridge mode allows wireless clients to acquire their IP address from the Metro DHCP server. Additionally, the client’s IP address is forwarded unchanged into the Metro network for authentication, auditing and security purposes. Note the client’s MAC address is been replaced by the MM2211’s Metro WLAN interface.
  • Full Tunnel Mode using L2TP – this feature is useful for Metro services that require client MAC address based authentication, or visibility of both the client IP and MAC addresses for audit or compliance reasons. A L2TP Network Server is required in the operators network to terminate the L2TP tunnels.
  • Always Up Wireless Gateway – when the WAN wireless goes down, the LAN wireless network is maintained up to allow the operation of ‘home wireless network’. This feature is available when the Metro Broadband Gateway is configured in Route mode.
  • Setup Wizard for ease of configuration – allow simple click and configure for three common types of deployment scenarios.
  • Comprehensive troubleshooting statistics – Per station SNR, throughput, packet error rate
  • Secured Remote Management (SNMP, SSH, HTTPS)
  • Preferred BSSID (preferred and locked modes) – to allow setting of the BSSID for the Metro Broadband Gateway to associate to.
  • Service Provider customizable defaults to allow a preset of the factory default parameters defaults to allow a preset of the factory default parameters

Can I upgrade from MM2211-DZ to MM2211-NG?

What antenna can I use to connect to the MM2211-EXT?

• The MM2211-EXT is currently only certify in the United States under FCC regulation to use with an omni or patch antenna of up to 9 dBi. It is not recommended to place the antenna outdoor, as lightning or humidity could affect both the antenna and the Metro Broadband Gateway. It is recommended to keep the antenna in an indoor location away from the hazardous environment.
• For Release 4.3 – the user will need to enable the use of external antenna via a WebUI selection. Once the external antenna is selected, the internal antenna will be disabled (for subsequent software release, this will be done automatically, and the internal antenna array will remain active). If the user wants to concurrently use the dual zone feature, then the user must use an omni external antenna.
