Applications for Elmatic Sparrow NW20 LTE Router

The functionality of the Sparrow NW20 router can be enhanced with dedicated extensions (applications). Below is the list of available ones:

AT over COM - An application that allows you to send AT commands to the router via the serial port.

AT over IP - Application sends AT commands to router via TCP/IP protocol.

AT over telnet - Allows you to send AT commands to the router via Telnet protocol.

DMVPN - Adds support for Dynamic Multipoint VPN (Cisco)

Dynamic Routing - Adds support for RIP, OSPF and BGP routing protocols.

IPsec - Adds IPsec technology for creating virtual private networks (VPNs)

L2TP - Adds support for L2TP protocol, or OSI Layer 2 tunneling.

PPTP - Adds support for PPTP protocol, a technology for creating virtual private networks.

SMS Gateway - Adds the ability to send SMS via predefined commands sent to the router's serial port.

VRRP - Adds support for Virtual Router Redundancy Protocol (VRRP).

The above applications can be downloaded at the bottom of this page, in the "Downloads" section.
