Moreover, the pandemic has shifted almost all activities to online mode, where the process requires the internet to run optimally and properly. Office work and campus assignments also require an internet connection. Not only for communication and entertainment. Almost all activities on various fronts nowadays require the internet. IEEE C95.The need for Internet access now seems to have become one of the primary needs. This document does not recommend specific peak spatial-average and whole-body average SAR limits since these are found in other documents, e.g. The extended frequency range up to 6 GHz will be considered in future revisions of this document. Positions that are typical of persons exposed to the fields generated by vehicle mounted antennas. It defines antenna locations, operating configurations, exposure conditions, and This document specifiesĪnd provides the test vehicle, human body models and the general benchmark data for those models.

This part of IEC/IEEE 62704 establishes the concepts, techniques, validation procedures, uncertainties and limitations of the finite difference time domain technique (FDTD) when used for determining the peak spatial-average and whole-body average specific absorption rate (SAR) in a standardized human anatomical model exposed to the electromagnetic fieldĮmitted by vehicle mounted antennas in the frequency range from 30 MHz to 1 GHz, which covers typical high power mobile radio products and applications. The procedures of this document do not apply to PD assessment of electromagnetic fields emitted or altered by devices or objects intended to be implanted in the body. The RF transmitting device categories covered in this document include but are not limited to mobile telephones, radio transmitters in personal computers, desktop and laptop devices, and multi-band and multi-antenna devices. The overall applicable frequency range of these protocols and procedures is from 6 GHz to 300 GHz. This document can be employed to determine compliance with any applicable maximum PD requirements of different types of RF transmitting devices used in close proximity to the head and body, including if combined with other RF-transmitting or non-transmitting devices or accessories (e.g. These devices may feature single or multiple transmitters or antennas, and may be operated with their radiating part(s) at distances up to 200 mm from a human head or body. These protocols and procedures apply for exposure assessments of a significant majority of the population including children during the use of hand-held and body-worn RF transmitting devices.

This standard specifies computational procedures for conservative, repeatable and reproducible computations of power density (PD) from radio-frequency (RF) transmitting devices incident to a human head or body, using Finite-Difference Time-Domain (FDTD) and Finite Element Methods (FEM) with a specified computational uncertainty.
