Caution:
1--Within 5.15 to 5.25 MHz bands, UNII devices are restricted to indoor operations to reduce any potential
harmfull interference to co-channel Mobile Satelite Systems (MSS) operations.
2--High power radars are allocated as primary users in the 5.25 to 5.35GHz and 5.65 to 5.85GHz bands. These
