802.15.4f-2012  -  IEEE Standard for Local and metropolitan area networks-- Part 15.4: Low-Rate Wireless Personal Area Networks (LR-WPANs) Amendment 2: Active Radio Frequency Identification (RFID) System Physical Layer (PHY)

Access Full Text at no charge from Get IEEE Program.

This amendment provides two PHYs (MSK and LRP UWB) that can be used in a wide range of applications requiring various combinations of low cost, low energy consumption, multi-year battery life, reliable communications, precision location, and reader options. This PHY standard supports the performance and flexibility needed for future mass deployments of highly populated autonomous active RFID systems anywhere in the world.

Scope
Change the first item of the dashed list as follows:-- Devices operating in the license-free 433.05 MHz to 434.79 MHz, 868 MHz to 868.6 MHz, 902 MHz to 928 MHz, and 2400 MHz to 2483.5 MHz, and 6289.6 MHz to 9185.6 MHz bands
Purpose
Change the second and third paragraphs as follows:In addition, one of the alternate PHYs provides precision ranging capability capabilities that is are accurate to one meter.Multiple PHYs are defined to support a variety of frequency bands including-- 433.05 MHz to 434.79 MHz (worldwide, varies by region)-- 868 MHz to 868.6 MHz-- 902 MHz to 928 MHz-- 2400 MHz to 2483.5 MHz-- 6289.6 MHz to 9185.6 MHz-- 314 MHz to 316 MHz, 430 MHz to 434 MHz, and 779 MHz to 787 MHz band for LR-WPAN systems in China-- 950 MHz to 956 MHz in Japan
