Wireless Mesh Networks

TELEGRID wireless mesh networks provide our military and commercial customers with a full range of products in this unique technology space.  Our products include WZRDnet, a handheld-based network for transporting voice and data in restricted environments such as tunnels, Proteus, a wideband long-distance network used to transport IP traffic such as streaming video, and AerialMesh, a drone-based “Fluid Topology” network which is dual-purposed able to transport both mission traffic (i.e., video) and drone telemetry information allowing drones to autonomously move in order to improve network performance.  Network security is the number ONE concern in all networks developed by TELEGRID.


AerialMesh – Airborne Wireless Mesh Network

The AerialMesh airborne wireless mesh network introduced a revolutionary new approach to network communications among Unmanned Aerial Vehicles (UAVs), i.e., drones.  The network supports communications of both mission traffic, e.g., streaming video, and drone telemetry traffic.  This dual purpose structure allows networked drones in flight to autonomously receive and process telemetry information from other drones and ground stations/ controllers and change their location, position, or other parameters in order to optimize network performance.  AerialMesh, is a Mobile Ad hoc Network (MANET) composed of drone-mounted nodes which include TELEGRID’s Multi-Input, Multi-Output (MIMO) radios.  It is an intelligent, dynamic, ad-hoc mesh network which provides a secure wideband Internet Protocol (IP)-based communications among drones and between drones and ground stations.  This allows drones to autonomously and in real time modify network topology as well as their working parameters in order to optimize network performance.  With AerialMesh the drones are constantly aware of the performance of the network and, if necessary, change their position or other parameters in order to optimize network performance.  The result is an autonomous network with fluid topology where nodes constantly re-position themselves and change their parameters as the environment changes in order to perfect network performance and extend drone endurance.

Proteus – Wireless Mesh Network

The TELEGRID Proteus Wireless Mesh Network is a flexible, ad-hoc, self-forming wireless network based on the 802.11/b/g/n IEEE standard. It is composed of a collection of stationary, mobile, or airborne nodes formed by TELEGRID Proteus Radios that operate in the 900 MHz, 2.4 GHz and 5.8 GHz frequency bands. Ad-hoc networks operate without a centralized access point or existing infrastructure and are self-forming and self-healing. They can be deployed in stationary architectures, such as with unattended ground sensors, or in mobile or airborne applications where network topology is unpredictable.

The main element of the Proteus Wireless Mesh Network is the Proteus Radio which is a modular radio that can be configures by the network architect to satisfy specific requirements.  This is done using the Proteus Node Configurator which helps determine which modules should be used and the total cost of the unit.  The radio is composed of the following four basic modules:

  • Dual Radio Module(2×2 MIMO)
  • Power Supply/ Battery Module
  • Sensors Interface Module
  • Touch-Screen Display Module

Options available for the Dual Radio Module include:

  • Two 2.4GHz Radios
  • Two 5.8GHz. Radios
  • One 2.4GHz/ 5.8GHz Radio and One 900MHz Radio

Options for the power supply module include AC power, DC power, rechargeable battery power or solar panel power.

The Proteus Radio design uses TELEGRID’s award winning Embedded Security Framework (ESF) which is a collection of DISA STIG/ SRG compliant encryption and authentication modules.  Combining the ESF with a LINUX OS Container means sensor network integrators no longer have to worry about integrating security at the edge.  The ESF handles all encryption and authentication including FIPS 140-2 compliance.  Data Sheet

WZRDnet Mesh Network

The TELEGRID WZRDnet Wireless Mesh Network is a low power ad-hoc network based on the IEEE 802.15.4 protocol, commercially known as ZigBee®.  WZRDnet provides secure voice and data communications without the need for an infrastructure (i.e. no cell towers or satellites required). In WZRDnet each device (i.e., handset or repeater) functions as a router in the network, relaying messages from originator to destination. Unlike other mesh networks, this architecture does not employ base stations or central routing tables thus avoiding single points of failure. WZRDnet is a true end-to-end packet switched network allowing transmission of voice, data and position location information (PLI).
