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 M915S-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.

Interference Mitigation
- The M900S Series offers powerful resistance to interference with the Automatic Repeat Request (ARQ) feature which automatically retransmits packets to mask RF errors to higher layer protocols. In addition, the system includes interference mitigation tools such as software selectable dual polarity antennas, automatic SU power leveling, and threshold control.

Integrated Design
- The M900S radios are fully weatherized outdoor units featuring Power-over-Ethernet (PoE) designed for quick deployment and easy installation.

Management Features
- The system offers remote and local management via Telnet, SNMP and HTTP via browser. Powerful tools such as site survey and upstream/downstream CIR/MIR controls allow operators total control and flexibility in managing their network.
