This article is about the ISO/IEC 18000-7 air interface standard.
Originally ratified in 2004, the standard was modified once in 2008, and modified again to its current version in 2014. ISO/IEC 18000-7:2014 provides technical specifications for
radio-frequency identification (RFID) devices operating in the 433 MHz band.
Specific attributes defined by the standard include
operating frequency, operating channel accuracy, occupied channel
bandwidth
Bandwidth commonly refers to:
* Bandwidth (signal processing) or ''analog bandwidth'', ''frequency bandwidth'', or ''radio bandwidth'', a measure of the width of a frequency range
* Bandwidth (computing), the rate of data transfer, bit rate or thr ...
, maximum power, spurious emissions,
modulation, duty cycle, data coding, bit rate, dit rate accuracy, bit transmission order, operating channel, chip rate, and attributes relating to
frequency-hopping spread spectrum
Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many distinct frequencies occupying a large spectral band. The changes are controlled by a code known to both tr ...
. The standard was created with the intention of promoting compatibility of devices within the international RFID market.
