1.2 iBeacon technical introduction

iBeacon broadcast frame using "announcement frame" (Advertising) to send the message, the

notice issued by a periodic frame with BLE devices (iBeacon), as long as the support BLE terminal

can receive the signal. Announcement frame payload portion, and writes the data defined by Apple.

iBeacon data mainly constituted by the four kinds of information, namely, UUID (Universal

Unique Identifier), Major, Minor, Measured Power. UUID is defined as ISO/IEC11578: 1996

standard 128-bit identifier. Major and Minor iBeacon set by the owner, is a 16-bit identifier. For

example, stores can use UUID name on behalf of the head office, Major representatives of regional

names, Minor behalf of a shop name Measured Power is iBeacon distance between the module and

the receiver reference received signal strength at 1 m. (RSSI: Received Singnal Strength Indicator) ,

the receiver of the reference RSSI based on the intensity of the received signal to the receiver

module and calculating iBeacon distance.

As Measured Power, because Apple's iOS is not careful in judging distance, while using only close

(Immidiate), 1m or less (Near), 1m or more (Far) from three kinds of states. When the distance less

than 1m, RSSI value is substantially proportional to the reduction, a more accurate distance, the

distance 1m in the above, the influence of the reflected waves and the like, RSSI but not

significantly reduce fluctuations. In other words, when you can not be inferred from the above 1m

apart, so simply judged Far.
