Scope
GB/T 26256-2010 is the English-translated version of 2.4GHz频段无线电通信设备的相互干扰限制与共存要求及测试方法.
GB/T 26256-2010 fixes the interference limits and coexistence requirements for wireless communication devices working in the 2.4 GHz band, together with the test methods that go with them.
Clause 1 gives the band as 2.4 GHz to 2.4835 GHz, divides the subject into radio frequency, multimode mutual interference and electromagnetic compatibility, and applies the standard to all wireless communication devices working in that band; no exclusion is stated.
As far as the draft reaches, the body runs Scope, Normative references and Terms, definitions and abbreviations.
The terms defined are the equivalent isotropic radiated power, taken as the radiated power of the EUT in a given direction set against the full power obtained from an antenna of 0 dB gain; the equivalent isotropic sensitivity, the minimum forward link power in one direction at which the EUT receiver can take what the base station sends in that direction; the total isotropic sensitivity, the integral of that sensitivity over the three-dimensional sphere around the EUT; the integrated antenna device, equipment without an external antenna connector whose antenna, internal or external, is part of the equipment; and the port, a specified interface between the device and the external electromagnetic environment.
The abbreviation list then begins with AP for Access Point and ACK for Acknowledgement, where the draft breaks off.
The foreword records that the standard was drawn up with reference to ETSI EN 300328 on electromagnetic compatibility and the radio spectrum for wide band modulation data transmission equipment in the 2.4 GHz ISM band and to other standards, and that in drafting it account was taken of harmonisation with YD/T 1312.1 and YD/T 1484.
Clause 2 cites YD/T 1312.1, YD/T 1484 and ETSI EN 300328. It was proposed by the Ministry of Industry and Information Technology of the People's Republic of China and administered by the China Communications Standards Association, with Nokia Telecommunications Limited among the drafters named. It was issued on 2011-01-14 and has applied since 2011-06-01.

Foreword
This standard reference ETSIEN300328 "Electromagnetic compatibility and Radio spectrum. Working in a wide frequency band using 2.4GHzISM Data transmission equipment with modulation techniques "and other standards were developed.
This standard is also in the process of drafting a note with the following harmonized standard. YD/T 1312.1 "wireless communication device electromagnetic compatibility limits And measuring methods - Part 1: General requirements" and YD/T 1484 "mobile station radiated RF power and receiver performance measurements". The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China. The standard by the China Communications Standards Association.
1 Scope
This standard specifies the work to limit interference (2.4GHz ~ 2.4835GHz) bands in the 2.4GHz wireless communication device And coexistence technical requirements, including radio frequency, multimode mutual interference and electromagnetic compatibility of three parts, and provides the corresponding test methods.
This standard applies to all staff within the 2.4GHz band wireless communication device.
