900 Mzh Trango Wireless SU Unit
Only 1 available
Shipping: US-Mainland: $25.00 (more destinations)
900 MHz Wireless Radio, Non-line-of-sight
Broadband Wireless Access Network
• Up to 20-mile range, 18 dB fade margin
• 3 Mbps usable subscriber throughput
• 4 non-overlapping channels, 6 MHz apart
• Dual polarized antenna, external antenna connector
• Robust interference rejection (ARQ)
• Deliver broadband Internet through foliage and other obstructions
• Easy management via Telnet, SNMP or HTTP Web browser
The M900S Series point-to-multipoint wireless broadband internet access (BWA) platform utilizes the advantages of the 900 MHz license-exempt spectrum and delivers up to 3 Mbps to the subscriber unit. Ideal for non-line-of-sight (NLOS) deployment, this fully integrated outdoor system includes internal dual polarized antennas as well as connectors for optional external antennas.
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 900 MHz 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.
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
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 la900 MHz 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 tency for active subscribers.
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.
The M900S radios are fully weatherized outdoor units featuring Power-over-Ethernet (PoE) designed for quick deployment and easy installation.
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.
