Overview 1.1 Scope This standard defines the air interface for radiating transceiver radio tags using long wavelength signals (kilometric and hectometric frequencies, 450 kHz). Conforming devices can have very low

35、power consumption (a few microwatts on average), while operating over medium ranges (0.5 to 30 meters) and at low data transfer speeds (3009600 bps). They are well suited for visibility networks, sensors, effectors and battery operated displays. This standard fills a gap between non-network-based RF

36、ID standards (e.g., ISO/IEC CD 15961-3, ISO 18000-6C or ISO 18000-7) and existing high bandwidth network standards such as IEEE 802.11 and IEEE 802.15.4. 1.2 Purpose The purpose of this standard is to define the air interface for radio tags optimized for use in visibility networks, where presence, i

37、dentity and associated data can be determined from stationary or moving tagged items, in situ, within relatively arbitrary storage areas. In situ in this context means that it is not necessary to either move the tagged items into closer proximity of a reader nor to move a reader into closer proximit

38、y of tagged items in order to identify the presence of a tag or to read or modify tag information. IEEE Std 1902.1-2009 IEEE Standard for Long Wavelength Wireless Network Protocol 2 Copyright 2009 IEEE. All rights reserved. In addition to visibility networks, applications for the radio tags describe

39、d in this document include sensors, effectors, battery operated displays and zero configuration peer to peer networks. This standard will facilitate compatibility and encourage inter-operability of routers, readers, base stations and radio tags from multiple manufacturers. It is expected that additi

40、onal standards under the IEEE 1902 identifier will provide other physical link options, command sets and standardization of commands and operations for specific vertical market applications. This standard specifies operation in the 47CFR15.209 emission regulation environment where field strength lev

41、els are below the threshold of regulation and thus permits operation world wide without requiring action on the part of regulatory bodies or the acquisition of special site licenses. This standard specifies: The functions and services required by an IEEE 1902.1 compliant device to operate within ad

42、hoc networks. The MAC procedures to support the delivery of MAC service data units (MSDU). PHY signaling techniques and interface functions. Operation of IEEE 1902.1 compliant devices within a wireless network that may co-exist with multiple other overlapping IEEE 1902.1 networks. 2. Normative refer
