WSA0326 – Vertexcom Wi-SUN FAN 1.0 Solution
The critical feature of VC735X is the concurrency of FSK and OFDM at any data rate. This means VC735X not only supports FSK 50/100/150/200/300/400/600 Kbps, 1 Mbps data rate but also has a proprietary FSK/OFDM concurrency, also known as FSK/OFDM Auto Mode Detection. In which the Rx can automatically detect whether the incoming packet is FSK or OFDM, so the Tx can transmit whatever mode it prefers without informing the Rx in advance. In other words, the leading FSK packet is no longer required, improving the transmission rate and routing efficiency.
Another feature of VC735X is that it is compatible with Wi-SUN FAN 1.0 and FAN 1.1. Compared with the original FAN 1.0, the new version of FAN 1.1 features a higher data rate. Since FAN 1.1 supports OFDM modulation, the data rate increased from 150 kbps to 2.4 Mbps. VC735X can provide up to 3.6 Mbps proprietary data rate. Secondly, FAN 1.1 supports FSK modulation at the same time, and VC735X can selectively support switching between FSK, and OFDM, with different data rates.
