NETWORK COEXISTENCE AIRTIME SHARING
Technologies related to network coexistence is described. A wireless personal area network (WPAN) module receives a first message with a length value corresponding to a length of the first message. A wireless local area network (WLAN) module obtains the length value. The WLAN module sends a second message over the WLAN that prevents other devices from sending traffic over the WLAN for an amount of time based on the length value.

determine, based on the historical messages, that a CRC threshold is satisfied, wherein the amount of time is based on the length value in response to the CRC threshold being satisfied.
14 . A method of operating a first wireless device, the method comprising:
sending a first message via a first protocol to a second wireless device, wherein the first message prevents the second wireless device from sending traffic over a network corresponding to the first protocol for a predetermined amount of time;
receiving, from a third wireless device, a second message via a second protocol comprising a length value corresponding to the length of the second message; and
sending a third message via the first protocol to the second wireless device, wherein the third message prevents the second wireless device from sending traffic via the first protocol for a variable amount of time based on the length value.
15 . The method of claim 14 , wherein the predetermined amount of time is based on a minimum possible length of the second message, and wherein the variable amount of time is based on a payload of the second message.
