You are working with the Sheriff's Department to develop a public safety wireless network that will be secured from interference and have the capability of delivering up 10 Mbps subscriber speed. What

The 2.4 GHz band is an unlicensed ISM band heavily shared with consumer devices including microwaves and Bluetooth equipment, making it highly susceptible to interference and unsuitable for a secured public safety network.

The FCC allocates the 4.9 GHz band solely to licensed public safety entities such as law enforcement agencies, which eliminates interference from commercial or consumer devices. It supports broadband wireless throughput up to 54 Mbps, comfortably exceeding the 10 Mbps subscriber requirement. This licensed exclusivity makes it the appropriate choice for a sheriff's department deployment.

The 5.0 GHz range falls within unlicensed U-NII bands used by commercial Wi-Fi (802.11a/n/ac), which are open to any user and provide no interference protection required for public safety communications.

The 5.3 GHz range is within the unlicensed U-NII-2A band and is not reserved for public safety use, offering no regulatory protection against interference from other wireless systems.
