False. Non-line-of-sight (NLOS) transmissions in the 802.16 standard, also known as WiMAX, are not limited to the 2 to 11 GHz bands. WiMAX operates in various frequency bands, including both licensed and unlicensed spectrum. While certain frequency bands within this range may offer better NLOS propagation characteristics, WiMAX technology can be deployed in other frequency bands as well. The choice of frequency band for a WiMAX deployment depends on factors such as regulatory approval, local interference, and specific use-case requirements.
