Just wondering whether Cambium got a 900Mhz solution?
900Mhz works well on NLOS.
Link: Point to Point
Elevation of the Antenna: 5m from the ground level both sites
Distance: 1km
Bandwidth Requirement: minimum 20mbps up & down
NLOS: There is a house roof on the path.
Sajeewa,
Yes, Cambium has had a 900MHz solution in the PMP 100 Series of radios.
