13. 4.9 GHz Band Plan Eight Channels of 5MHz (40 MHz total)
Ten Channels of 1MHz (10 MHz total)
Per FCC rules ( ),these channels can be aggregated to channel bandwidths of 5, 10, 15, or 20 MHz.
The maximum bandwidth of a 4.9GHz channel is 20 MHz.

14. Who can use 4.9Ghz?
Public Safety services as defined under Part 90 rule section are eligible to hold a 4.9 GHz license.
All state or local governmental entities (including municipal utilities) are eligible to hold 4.9 GHz licenses.
Entities not eligible to hold a license, but which perform operations in support of public safety, (such as private critical infrastructure industries) can negotiate sharing agreements with 4.9 GHz public safety licensees.
Sharing of systems must be by written agreement between the licensee and the party sharing the system and all communications by the non-licensee must be in support of public safety, related to the protection of life, health or property.
The federal government is not eligible to hold 4.9 GHz licenses but can share state and local public safety systems.
