Overview

Homeland Defense Departments, Security Agencies, Governments and other organizations require higher levels of perimeter security today than ever before. Two key elements of modern security strategy include video surveillance and extension of wireless data access for security personnel. But extending these services along borders, perimeters, in wilderness areas or congested downtowns often requires many (node-to-node) hops. These demanding military and security wireless applications require secure, high-speed connectivity for data, video and voice. Patented and patent-pending technology utilizes multiple backhaul radios to provide near-instantaneous network set-up, node mobility at high speeds, high bandwidth, and minimal delay and jitter.

Mobile Mesh Network Capabilities:


Each Meshdynamics wireless mesh node incorporates a sophisticated RF 'robot' which monitors the radio environment to locate adjacent nodes and avoid interfering and jamming sources. Each node operates in an independent yet coordinated manner to build the network topology. In mobile environments, high performance is maintained as the node automatically and transparently connects to other stationary or mobile nodes. [Visual]

In a deployed combat environment, vehicle-mounted Meshdynamics MD4000 wireless mesh nodes demonstrated reliable connectivity between multiple convoy vehicles in simultaneous motion. The threat sensor application supported by the Meshdynamics network operated flawlessly as the vehicles moved through a rugged outdoor environment.

Deployment along the Arizona-Mexico border:

Border and perimeter security environments demand high performance over extended distances for date, voice and surveillance and tactical video. In most cases, wired or fiber connectivity is unavailable, so the network must be delivered wireless over many hops (node to node connections). Meshdynamics' patented and patent pending third-generation wireless mesh architecture delivers bandwidth with minimal delay and jitter over many hops. In addition, the Meshdynamics network functions as a Layer 2 switch infrastructure, transparent to a wide variety of sensor and video streams.

In a successful long-term pilot network across the Arizona-Mexico border, Meshdynamics nodes are providing connectivity for a variety of security applications to mobile border security forces. Node-to-node distances reach up to 14 miles. [News Article]  

Hastily formed military and civilian networks:

Meshdynamics products are also being utilized in a variety of hastily formed military and civilian networks. Threat sensors, data, video and even sports-scoring applications are supported over Meshdynamics networks that deploy over broad geographical areas in a few minutes. Network start-up is automatic and immediate when power is applied to the nodes. No site survey or channel pre-configuration is necessary: the distributed dynamic radio intelligence in each node manages the complete network set-up process. Meshdynamics units are compact and rugged, making for limited transport cost and weight.

Every week during the season, fans gather at a different outdoor venue for events scheduled by a global professional sporting organization. Besides a glimpse of their favorite players, fans want access to constantly updated scores and standings. The sporting organization positions large scoreboards around the event to provide these statistics, but connecting the displays to the scoring computers required a high performance wireless network that was fast to set up and easy to manage.
 
MD4000 nodes are being deployed each week around the event locations, creating a high-performance, low-latency and low-jitter infrastructure connecting the scoreboards to powerful computers processing scoring data from around the venue. The sporting organization maintains multiple sets of nodes: while one is being set up and used, another is in transit to the next event. More
