1. A method of increasing data bandwidth to a wireless client device, comprising:
- receiving a data message from the wireless client device;
transmitting multiple parts of a response data message to the wireless client device across two types of wireless communication channels simultaneously by;
transmitting a first part of the response data message to the wireless client device across a first wireless communication channel via a selected one or more transmitters of an array of two or more transmitters of a first transmitter type that in combination cover one or more areas of a room;
simultaneously transmitting a second part of the response data message to the wireless client device across a second wireless communication channel via one or more transmitters of a second transmitter type, different than the first transmitter type; and
encoding the first part of the response data message transmitted to the wireless client device over the selected one or more transmitters of the array of two or more transmitters of the first transmitter type, wherein the encoding is based on a location of the wireless client device in the room with respect to two or more transmitters in the array of transmitters of the first transmitter type.

Abstract
Techniques and solutions are provides for increasing data bandwidth to wireless devices in a wireless network. Data bandwidth to a wireless device can be increased by using an array of wireless transmitters of one type, arranged to cover one or more areas of an enclosed space, in combination with one or more wireless transmitters of another type, to simultaneously transmit data to the wireless device over different wireless communication channels.
