M900S Series 900 MHz Point-to-MultiPoint Outdoor Ethernet Bridges

900 MHz Non-Line-of-Sight Performance
The M900S Series was designed for deployment in areas where foliage and other obstructions obscure line-of-sight between the access point (AP) and subscriber unit (SU). The system offers excellent receiver sensitivity and best-in-class overall system gain for outstanding non-line-of-sight (NLOS) range. The subscriber can expect typical NLOS performance of up to 6 miles or beyond. Use of external antennas increases range and fade margin even farther. In addition, Spread Spectrum modulation promotes resistance to multipath fading. Combining Trango's state-of-the-art SMARTPolling™ with Spread Spectrum modulation results in maximum cell performance.

Antenna Flexibility
The M900S AP and SU each include an integrated 10 dBi dual polarized patch antenna as well as a connector for optional external antennas. The lower cost M915S2-SU-EXT features only a connector for an external antenna. External antenna options include omni antennas for the AP and yagi-style antennas for both the AP and SU. The auto-sensing feature on the M900S SU allows the firmware to choose the antenna with the strongest signal, or the user can manually select either the internal or external antenna.

Speed
The system delivers up to 3 Mbps and utilizes Trango's patented SMARTPolling™ algorithm (U.S. patent 7,127,255) to dynamically and adaptively poll subscriber units, ensuring the lowest latency for active subscribers.

Channel Flexibility
The system is configured with four channels, each 6 MHz apart. The user can redefine channels by selecting frequencies in single MHz increments. The SU scans all channels until it associates with a properly configured AP. This allows redundancy of APs as well as a simple and quick method to switch channels on an entire sector.
