2.4 GHz Wireless Radio High-Speed Broadband Wireless Access System
- Up to 25-mile range, 10 dB fade margin
- 5 Mbps usable subscriber throughput
- 2400 MHz to 2483 MHz
- 8 channels, narrow 10 MHz channel size
- Up to 128 subscriber units per access point
- Easy management via Telnet, SNMP or HTTP Web browser
- ARQ and automatic SU power leveling for interference mitigation
The M2400S™ point-to-multipoint 2.4 GHz wireless broadband Internet access (BWA) platform offers service providers and network operators a cost effective, enterprise-grade solution for fixed wireless connectivity. The system provides up to 5 Mbps to the subscriber unit and a range of 25 miles. The M2400S utilizes a narrow 10 MHz channel compared to 20 MHz for 802.11-based systems, making it highly resilient in the presence of in-band interference.
The M2400S Access Point (AP) and Subscriber Unit (SU) 2.4 GHz radios both include integrated dual polarized patch antennas as well as a connector for an optional external antenna. Utilizing the internal antennas, the M2400S provides a range of 15 miles line-of-sight (LOS) with 10 dB fade margin to spare. Range can be extended to over 25 miles by attaching an optional grid antenna to the SU. On the AP, operators can utilize the internal sector antenna or attach an external sector or omni antenna.
The M2400S is one of the most flexible 2.4 GHz systems available with eight channels that users can redefine by selecting frequencies in single MHz increments. The SU will scan 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. In addition, the software switchable dual polarized antennas allow for outstanding frequency agility.
The M2400S delivers up to 5 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.
The M2400S offers powerful resistance to interference with the Automatic Repeat Request (ARQ) feature, which automatically re-transmits errored packets to mask RF errors to higher layer protocols. In addition, the M2400S provides mitigation tools such as dual polarity antennas, automatic SU power leveling, and threshold control.
The M2400S radios are fully weatherized outdoor units featuring Power-over-Ethernet (PoE) designed for quick deployment and easy installation.
Security & Authentication
The M2400S offers MAC-level authentication coupled with over-the-air data scrambling for secure operation.
The M2400S offers remote and local management via Telnet, SNMP and HTTP via browser. Tools such as site survey and upstream/downstream CIR/MIR controls allow operators control and flexibility in managing networks.

Exclusive PtMP Technology
SMARTPolling™ (U.S. patent 7,127,255) is a unique and powerful prioritization scheme designed to ensure the highest quality of service, such as VoIP, to each user at the maximum assigned throughput. The AP will poll each SU in a round-robin fashion, favoring subscribers which are busy passing traffic. For this reason the SMARTPolling™ protocol is adaptive and dynamic as opposed to straight Time Division Duplex (TDD). Added control of the polling sequence is provided by the ability for network operators to specify certain subscribers as PRIORITY in which case these subscribers will be polled more frequently thus guaranteeing even lower latency for critical clients.
