Hi test123. Keep in mind that this is a NLOS link with dense trees in a noisy environment, where the 5 GHz solutions with high speeds cannot reach. Given clear LOS and low noise levels PMP 450i speeds can be higher. Right now, the only 900 MHz option is PMP 100 FSK, which has a much lower throughput.
Check out the PMP 450i 900 MHz webinar for our discussions of the product and performance.
We are being very up front about what to expect.
