Carrier-sense multiple access with collision avoidance ( CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". [1] [2] When they do transmit, nodes transmit their packet data in its ...
Multiple Access with Collision Avoidance for Wireless. Multiple Access with Collision Avoidance for Wireless ( MACAW) [1] is a slotted medium access control (MAC) protocol widely used in ad hoc networks. [2] Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2]
Apple.com – Keyboard. The Apple Wireless Keyboard is a wireless keyboard built for Macintosh computers and compatible with iOS devices. [1] It interacts over Bluetooth wireless technology and unlike its wired version, it has no USB connectors or ports. Both generations have low-power features when not in use.

v. t. e. In IEEE 802 LAN/MAN standards, the medium access control ( MAC ), also called media access control, is the layer that controls the hardware responsible for interaction with the wired (electrical or optical) or wireless transmission medium. The MAC sublayer and the logical link control (LLC) sublayer together make up the data link layer.
IEEE 802.11e-2005. IEEE 802.11e-2005 or 802.11e is an approved amendment to the IEEE 802.11 standard that defines a set of quality of service (QoS) enhancements for wireless LAN applications through modifications to the media access control (MAC) layer. [1] The standard is considered of critical importance for delay-sensitive applications, such ...
A wireless light switch is a light switch that commands a light or home appliance to turn itself off or on, instead of interrupting the power line going to the light fixture. There are different ways to communicate between the switch and the fixture: [2] Using radio transmission: A radio receiver is typically wired or screwed into a fixture or ...
