Wireless contention reduction

A non-transitory computer-readable medium comprising instructions, the instructions, when executed by a computing system, cause the computing system to perform operations for reducing access contention in a network, the operations comprising:

• determining, by a transmitter, a likelihood that a client device will generate one or more TCP ACK packets as a predicted response packet type in response to a data packet transmitted to the client device, wherein the predicted response packet type is predicted based on a model of response types and response durations;
• predicting, by the transmitter, a response time when the predicted response packet type will be received from the client device in response to the data packet transmitted to the client device, wherein the response time is predicted based on the model of response types and response durations;
• determining, based on the predicted response packet type and the response time, an extended duration field value which corresponds to a time duration from a time that the data packet is transmitted until at least a time when a response comprising the predicted response packet type will be received from the client device;
• and
• transmitting the data packet to the client device, wherein the data packet comprises the extended duration field value, and wherein the data packet transmitted to the client device is configured to suppress transmission by one or more devices other the client device during the time duration corresponding to the extended duration field value.
