This standard provides definitions and explanations of key concepts in the fields of spectrum management, spectrum trading, cognitive radio, dynamic spectrum access, policy-based radio systems, software-defined radio, and related advanced radio system technologies. The document goes beyond simple, short definitions by providing amplifying text that explains these terms in the context of the technologies that use them. The document also describes how these technologies interrelate and create new… read more capabilities while at the same time providing mechanisms supportive of new spectrum management paradigms. This revision to IEEE Std 1900.1-2008 adds additional definitions, modifies existing definitions, and removes outdated definitions; it updates the auxiliary text and informative annexes to reflect new concepts and developments in advanced radio systems; introduces a taxonomy of terms which depicts relationships between definitions and concepts, and updates the document structure to align revised definitions, concepts, and relationships between terms and definitions. read less

This guide provides guidance for using radio frequency (RF) wireless communication technologies for ISO/IEEE 11073 point-of-care (PoC) medical devices that exchange vital signs and other medical device information using shared information technology (IT) infrastructure. Use cases specific to these technologies are evaluated, and key functional and performance criteria are identified, including quality of service (QoS) management, privacy and security, coexistence with other RF wireless… read more technologies, environmental requirements such as electromagnetic interference and compatibility (EMI/EMC), and power management. Guidelines are provided for each of these areas. Technologies include, but are not limited to, the IEEE 802.11 and IEEE 802.15 technologies. Use case environments include traditional clinical settings as well as personal (home and mobile) healthcare. The intent of guide is to be global with respect to wireless spectrum and equipment, although working group participation and expertise have favored detail of scenarios from the United States. Importantly, this guide will not be periodically updated, but instead will act as a source of information for follow-on ISO/IEEE 11073 RF wireless transport standards that will supersede it. These ISO/IEEE 11073 RF wireless transport standards will detail the use of specific wireless networked technology for the purpose of transporting medical data. Periodic updates will be performed on the ISO/IEEE 11073 standards only. read less

The scope of this standard is to define an IrDA-based transport profile for medical device communication that uses short-range infrared, as a companion standard to IEEE Std 1073.3.2, which specifies a cable-connected physical layer. The proposed standard will also support use cases consistent with industry practice for handheld PDAs and network access points that support IrDA-infrared communication.

The recommended practice defines test approaches to quantify the interference of passive intermodulation (PIM) from handheld devices, base stations, and satellite earth stations. Current PIM noise tests for communication components/devices/antennas/systems do not work well at extremely low PIM levels or high transmission power levels, for example where PIM noise falls below -150 dBc.

This standard specifies the application service layer and profile for Payment and Identity authentication, and Payment Data transfer for Dedicated Short Range Communication (DSRC) based applications using IEEE Std 802.11(TM) and IEEE 1609 protocols in Wireless Access in Vehicular Environments. This standard defines a basic level of technical interoperability for electronic payment equipment, i.e., onboard unit (OBU) and roadside unit (RSU). It does not provide a full solution for interoperability, and it does not define other parts of the electronic payment-system, other services, other technologies, and non-technical elements of interoperability. This standard is not intended to define technology and processes to activate and store data into the OBU (personalization).

The Internet of Things is predicted to consist of billions of devices by 2020. Many of these devices will run on batteries. To prolong the useful life of these batteries, while making sure devices don t stay in a sleep state too long and run slowly, devices must be able to run in a low-power, low-latency state. Wake-Up Radio, which is being developed by the IEEE 802.11ba working group, offers a solution to this challenge.
