Beacons with support from Eddystone are able to transmit three different frame-types, which work with both iOS and Android. [3] A single beacon can transmit one, two or all three frametypes. The three frametypes are: Beacon protocol - Google's Eddystone
A beacon frame consists of an 802.11 MAC header, a body and a frame check sequence (FCS). [1] Some of the fields in the body are listed below. Timestamp After receiving the beacon frame all the stations change their local clocks to this time. This helps with synchronization. Beacon interval This is the time interval between beacon transmissions.

Eddystone also contains a telemetry frame (Eddystone-TLM) designed for reporting on a beacon's health, including, for example, battery level. Like other beacon technology, beacons with Eddystone can give devices a better indication of what objects and places are around them. [ 4 ]
Ethernet packet. The SFD (start frame delimiter) marks the end of the packet preamble. It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport
Texture streaming is a means of using data streams for textures, where each texture is available in two or more different resolutions, as to determine which texture should be loaded into memory and used based on draw distance from the viewer and how much memory is available for textures. Texture streaming allows a rendering engine to use low ...
As of May 2014, different hardware iBeacons can be purchased for as little as $5 per device to more than $30 per device. [20] Each of these different iBeacons have varying default settings for their default transmit power and iBeacon advertisement frequency. Some hardware iBeacons advertise at as low as 1 Hz while others can be as fast as 10 Hz ...
Action frames extend management frames to control a certain action. Some of the action categories are QoS, Block Ack, Public, Radio Measurement, Fast BSS Transition, Mesh Peering Management, etc. These frames are sent by a station when it needs to tell its peer for a certain action to be taken.
