Wireless Mesh Products

TELEGRID has developed several wireless mesh network radios.  They include the modular Mobile ad-Hoc Network (MANET) uMESH radio which can be configured to satisfy specific customer requirements.  One of the configurations includes a large rechargeable battery set that allows the radio to operate in the field for over 24 hours.  Since TELEGRID embraces open-source platforms such as OpenWRT and the open routing protocol B.A.T.M.A.N. our systems easily integrate with other wireless mesh products and benefit from the rapid development of the open source community.  A uMESH radio has been mounted on a drone and successfully tested as a tactical range extension capability.


uMesh – Wireless Mesh Network

The TELEGRID uMesh 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 uMesh 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 uMesh Wireless Mesh Network is the uMesh Radio which is a modular radio that can be configures by the network architect to satisfy specific requirements.  This is done using the uMesh 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 uMesh 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).
