The scope of this project is limited to incorporating the changes between 802-15-1-2002 (Bluetooth specification 1.1) and Bluetooth Specification 1.2 into 802-15-1-2002. The scope of the original project was: To define PHY and MAC specifications for wireless connectivity with fixed, portable and moving devices within or entering a Personal Operating Space (POS). A goal of the WPAN Group will be to achieve a level of interoperability which could allow the transfer of data between a WPAN device… read more and an 802.11 device. A Personal Operating Space (POS) is the space about a person or object that typically extends up to 10 meters in all directions and envelops the person whether stationary or in motion. The proposed WPAN Standard will be developed to ensure coexistence with all 802.11 Networks. read less

This recommended practice provides an SDN-based architecture for multi-radio access technology (RAT ) wireless access networks. It also specifies an SDN-based middleware to support unified and vendor independent control and management of the data plane functions belonging to different RATS, such as wireless local area networks (WLANs), wireless regional area networks (WRANs), and other terrestrial radio access systems [e.g., those defined by the 3rd Generation Partnership Project (3GPP) and International Telecommunication Union Radiocommunication Sector (ITU-R)]. This document also recommends a logically unified multi-RAT control plane function. The control plane function is responsible for control and management of the multi- RAT access network with the help of the proposed middleware.

This standard specifies requirements for the use of consumer mobile devices (CMDs) in the control of diabetes-related medical devices. While these requirements may be applied to other medical use cases, they are targeted specifically for diabetes related control use cases. The following two use cases are covered by this standard: open loop remote control and automated insulin dosing (AID) systems. In general, the requirements within this standard apply to both use cases unless explicitly indicated otherwise.

This standard specifies physical and logical requirements that enable wireless backscatter networking systems to implement a software-defined physical layer (SD-PHY). The system comprises RF sources, tags and receivers (RF source and receiver can be integrated into one physical entity), where the RF source sends out excitation signals such as the continuous-wave (CW) RF signal to the tag; the tag modulates the excitation signal by impedance matching and then backscatters the modulated signal to… read more the receiver. The system architecture specified in this standard is similar to the Radio Frequency Identification (RFID) system, which however distinguishes itself from traditional RFID systems in the following two aspects: 1) The capability of using ambient RF sources, for example, IEEE 802.11 (Wi-Fi), Long Term Evolution (LTE), Bluetooth Low Energy (BLE) and Long Range (LoRa) as excitation signals; 2) the capability of adjusting the PHY layer behavior of the tag with software. The standard provides general requirements and protocols for implementing wireless backscatter networking system enabling SD-PHY as follows: - Physical interactions among RF sources, tags and receivers, including signaling and communication protocols. - Operating procedures and commands for reprogramming the PHY layer of the wireless backscatter system. - Schemes that support co-existing SD-PHY enabled backscatter networks and other already-deployed wireless infrastructures. read less

This standard provides recommended practices for the determination of uncertainty in the estimation of error vector magnitude (EVM) of a measured digitally modulated wireless communication signal. Such practices include several methods for validating a user's measurement of a specific reference waveform by comparison to a reference measurement. The methods differ based on the level of rigor desired by the user and the accessibility to timing and waveform recording capabilities of the available… read more hardware. Methods for evaluating measurement uncertainty in EVM are also presented. Some of the methods described here focus on measurements and uncertainties related to the use of laboratory-based measurement equipment such as vector receivers, real-time and equivalent-time sampling oscilloscopes and other types of waveform recorders that have access to the measured waveform. This allows time-alignment and gain normalization of measured waveforms prior to the calculation of EVM. Other methods focus on specialized receivers that report symbols directly. As part of the assessment of the measurement hardware and associated uncertainty analyses, this practice includes a mathematically rigorous method for the determination of EVM. read less
