What does DFS stand for?

Devices that utilize the new spectrum are required to use dynamic frequency selection (known more informally as listen-before-talk).

In addition to being highly scalable and flexible, BreezeMAX Extreme employs complex interference mitigation techniques to allow for robust performance especially since it targets license-exempt frequency bands, and implements dynamic frequency selection (DFS) and automatic frequency selection (AFS).

8GHz band will use Dynamic Frequency Selection (DFS) technology to minimise interference, which means that a users connection will automatically change to another channel if it detects military radar.

Some of these exceptional features include: * High spectral efficiency with high system gain for high capacity at long range * Unmatched integrated synchronization functionality for high density co-location applications * Software configurable receiver bandwidth, modulation, and capacity for maximum frequency reuse * Dynamic frequency selection (DFS) to meet worldwide regulatory requirements * Built-in spectrum analyzer for ease of deployment and RF environment monitoring * Software selectable antenna polarization for simple installation and reconfiguration * Software selectable transmit power for better RF control * Tri-band 5.

The new certifications are evidence of the company's compliance with the new Dynamic Frequency Selection requirements intended for preventing disruptions to military radars and enabling license-exempt fixed wireless broadband operators to increase their 5 GHz spectrum capacity significantly.

Incorporating Dynamic Frequency Selection (DFS), the AN-80i allows co-existence of wireless communications systems with traditional radar systems in the same frequency band.

with features such as roaming with seamless hand-offs at speeds up to 200 km/hr, WiMAX Quality of Service (QoS), and enhanced dynamic frequency selection (DFS).

Under his leadership, the NTIA set world-leading policies in a number of areas including, ultrawideband, millimeter wavelength communications, third-generation wireless services, dynamic frequency selection in the 5 GHz frequency band, and broadband over powerlines.
