GE MDS Intrepid is a 48 Mbps capacity (air interface max speed)/18 Mbps capacity (Ethernet max speed), cost effective, point-to-point, broadband wireless transmission system. It combines Ethernet and legacy TDM services for transmission over 5.8, 4.9, and 2.4 GHz bands and is suitable for deployment in FCC-regulated countries. Intrepid provides high performance and reliability. The interface ensures low BER, as well as low latency, and full compliance with the jitter and wander requirements for T1 interfaces. A transmission range of up to 80 km (50 miles) is available with an external antenna.

Intrepid consists of an outdoor unit (ODU) and an indoor unit (IDU or IDU-C). The outdoor unit is suitable for mast or wall installation. Mounting brackets are supplied with the unit.

Adaptive Modulation and Increased Frame Sizes

The Intrepid adaptively changes the modulation per air conditions for maximum rate and link stability. Intrepid also supports larger frames (1536 bytes for IDU) to improve Ethernet traffic efficiency and reduce the overall overhead.

Automatic Channel Selection and Additional Bandwidth Options

Wireless ISP Backhaul of their Point of When the link quality falls below a pre-set standard, Intrepid automatically searches for a clear channel within a pre-selected list of frequencies.

Intrepid v1.62 offers channel bandwidth options in addition to the 20 MHz channel bandwidth already supported. These options improve immunity to disturbances and enable deployment in high-interference environments.

Why use a GE MDS Intrepid Wireless Networking Solution?

Security - Data transmitted over the air is encrypted using (AES) 128-bit encryption.

Quality of Service - When the link quality is out of limits, unit locates a clear channel from a pre-selected list of frequencies.

Short Time-to-service - Because Intrepid operates in license-exempt frequencies, it can be deployed in record time, eliminating the costs and delays involved in leasing lines or trenching fiber.

Management - Factory settings can be restored at any time for each ODU. Information on links and management can be collected and analyzed with a single action. External events trigger alarms via the dry contact alarm inputs.
