GRC-5220 is the Orthogonal Frequency Division Multiple Access (OFDMA) based high capacity Ethernet radio designed for outdoor use in the tactical field to provide secure and reliable communication. GRC-5220 uses 2x2 Multiple Input Multiple Output (MIMO) technologies to provide high throughput and communication reliability.
GRC-5220 also provides Quality of Service (QoS) support to ensure the successful delivery of both bandwidth intensive and delay sensitive applications at the same time.
GRC-5220 radio system consists of two units: BaseBand Unit (BBU) and Radio Frequency Unit (RFU). Both units are designed to be used in harsh outdoor environments, such as the tactical battlefield. GRC- 5220 system ensures that two units can be seperated more than 1 km.
