Architecture Overview

DenseNode™ technology is typically deployed on buildings and/or light poles for ubiquitous wireless coverage in the intended coverage area. Relays are spaced about 600 to 800 feet apart in this architecture. The solution is different from other competing metro solutions because it does not utilize a strict routed or mesh architecture. DenseNode™ utilizes a 5GHz backhaul on dedicated radios for the upstream and downstream connections. This reduces media contention. Increased capacity and relay depth is achieved with this architecture because of the separation between customer and backhaul RF connections. Since the architecture maximizes RF channel availability, managing and mitigating interference is a simple process; compared to mesh solutions where all devices utilize the same channel space.

The patented hybrid network design utilizes both bridges and routers to reduce the overhead of IP routing latency and reducing jitter per hop below those of mesh solutions. This is critical for deployments that plan on utilizing voice or video applications that require low jitter and low latency. The system uses the 802.11b/g 2.4GHz frequency band for standard customer connections and utilizes 802.11e for QOS and outdoor rate control. This supports mobility options for users on laptops and other WiFi compatible devices.

Proven Reliability

The technology has been proven through the deployment of thousands of devices over a diverse geographic environment. Overall network availability of 99.99% allows operators the ability to compete with the local telephone company via VOIP, which increases revenue and market share. The hardware has built in static protection to reduce the problems and failures associated with static storms. The enclosures are industry grade access boxes with water tight, corrosion resistant connections.

Unlike mesh applications that attempt to utilize multi-radio designs, this technology was specifically built for our application and architecture. Both systems utilize directional, point to point connections between repeater locations without the use of complex, expensive multi-diversity antenna arrays or phased array antennas.
