This standard applies to both wireless communications devices (WDs) and hearing aids. It sets forth uniform methods of measurement and parametric requirements for the electromagnetic and operational compatibility of hearing aids and WDs, including cellular phones, personal communications service (PCS), and voice-over-Internet-protocol (VoIP) devices, operating in the range of 614 MHz to 6 GHz. TIA-1083, Telecommunications Communications Products Handset Magnetic Measurement Procedures and… read more Performance Requirements [B87], has become the recognized standard for measurement procedures and performance requirements for handset-generated audio band magnetic noise of wireline communications devices, including cordless telephones (cordless handsets with wireline-connected base units). Ongoing communications between the TIA TR-41.3.14 accessibility working group and ANSI C63.19 working group have been maintained with the objective of harmonizing the two standards to the maximum extent possible. This standard is intended to apply to all types of hearing aids with acoustic output, including, as examples, behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC), completely-in-the-canal (CIC) types, and receiver-in-the-canal (RIC). Test methods are provided for acoustic (microphone input) mode and tele-coil (T-Coil) hearing aid modes of operation. Users of this standard are cautioned to maintain the field strength called for in various places in the document within the limits for radio-frequency (RF) safety specified in IEEE Std C95.1(TM) [B65]. read less

This is a standard for short-range, wireless communication in the vicinity of, or inside, a human body (but not limited to humans). It uses existing industrial scientific medical (ISM) bands as well as frequency bands approved by national medical and/or regulatory authorities. Support for quality of service (QoS), extremely low power, and data rates up to 10 Mbps is required while simultaneously complying with strict noninterference guidelines where needed. This standard considers effects on… read more portable antennas due to the presence of a person (varying with male, female, skinny, heavy, etc.), radiation pattern shaping to minimize specific absorption rate (SAR) into the body, and changes in characteristics as a result of the user motions. read less
