URBAN URB4020
Dual-band, Dual Radio WiFi/Hiperlan2 Wireless Lan Appliance

Effective Dual Frequency	URB4020 includes two radio modules which can independently operate in one of the two available frequency bands. The device can be customized for the most diverse application scenarios by connecting different external antenna types (directive, sectorial, omnidirectional, etc.). Output power limitation allows the use of high-gain antennas while conforming to regulations on radiated energy levels.
Flexibility - Mesh Networking	Each radio module can be separately configured for Access Point, Bridge or Station operation; the modules are internally connected through IP routing. Urban products support a proprietary protocol for the creation and management of mesh networks.
Access Point with Bandwidth Management	Urban appliances allow comprehensive bandwidth management. Both the upstream bandwidth and the resources available to each client can be monitored, prioritized and limited as required in order to attain the desired Quality of Service levels.
Optimized for performance: 108Mbps	Urban products feature the “turbo”, “nstreme” and “dual-nstreme” transmit modes, enabling specific data rate and throughput optimizations which allow to achieve effective bit rates of up to 108 Mbps.
