毫米波以太网链路设备350/1250Mbps
发布时间:2017-08-11 15:52 访问次数:

ELVA-1 announces new full-duplex 350Mbps/1250Mbps Series of 40.5-43.5 GHz and 71-76/81-86 GHz mm-wave bands Radio Links. PPC-350 was specifically designed according to European ECC and US FCC performance requirements. Main feature of PPC-350 consists in possibility to adapt its data transmission speed to the current weather conditions.

PPC-350 supports Adaptive Code and Modulation (ACM) in which changers of coding rate and modulation are set in real time, based on the link conditions. This feature enables to increase radio link availability.

When the link`s SNR (Signal to Noise Ratio) is high (during good weather conditions), operation at full capacity is enabled, reaching the maximum speed of 350Mbps. In case that the link`s SNR drops significantly (during heavy rain), the channel capacity is reduced up to 80Mbps.

The figure shows radio bridge capacity varies due to changers in SNR level.
