Description

The GDI Frequency Hopper line of spread spectrum radios provides an off-the-shelf, ready-to-install solution to a number of long-range communication applications. The product was designed from the ground up with emphasis on performance, reliability, and flexibility and has been qualified under the most stringent temperature, shock, and vibration.

Interference Blocking

Through the use of a proprietary hardware and software technology, The GDI frequency hopping radios are virtually immune to most RF interference (cell phones, pagers, other wireless systems, etc.).

Fast Synchronization

The GDI frequency hopping radios are able to synchronize with each other in less than 35 milliseconds. The GDI frequency hopping radios are inherently peer-to-peer instead of Master/Slave. This means that the radios communicate with NO configuration and support very flexible networking topologies. In the default mode of operation, the radios synchronize the transmitter and receiver before each communication. Re-synchronization with each transmission allows the system to recover quickly from interference. A radio can communicate immediately after power up without waiting for any synchronization. Also, there is no need to stay synchronized during sleep or low power modes allowing the radio to have power down modes as low as 26 micro-amps. Configurable low latency operating modes reduce the synchronization time as little as 8 ms.

Network Configurations

The GDI products can be set up for a wide variety of network configurations. These configurations include point-to-point, multi- point-to-point, “star” networks, and point-to-multipoint links.
