The QMTS is a multi-role communications VPN platform designed to simultaneously utilise the wireless data networks of up to four mobile network operators in a single geographic location. Data are transmitted and received across the available carrier networks to a central concentrator server, the QRMS, before being forward to any number of configured client PCs, smartphones, other QMTS devices or to the Internet. Splitting the data across multiple networks leads to higher throughput and greater resilience in the overall link seen by applications and users, while also offering latency control where different link qualities or technologies are present.

A QMTS operates an integrated router that manages packet queues internally and transparently to other network equipment. This provides a LAN-like VPN between devices and exposes full IP connectivity between client PCs and equipment while requiring minimal setup or configuration. Encryption and authentication of each individual link secures all traffic within the VPN, while the QRMS server can also apply policies to partition the VPN or block devices as required.

Each QMTS contains an integrated 2 port Ethernet switch to which other equipment can be connected, and through use of a USB WiFi dongle, a hotspot for VPN access can be provided. Optionally one Ethernet port can also be configured to use as WAN backhaul, allowing the QMTS to operate the VPN over any public fixed line, leased line or other network link such as satellite. When using WAN backhaul, the wireless modems then add redundancy or extra bandwidth, should the WAN link fail or be insufficient for application traffic.

Built-in GPS allows the position of each QMTS to be tracked, while other connectivity such as USB, CANbus and GPIOs allows for specialist integration, control or monitoring of other equipment without needing additional hardware. A simple SDK is available through which applications can be added directly to the QMTS.
