2、roposed by the Working Group “Frequency Management“ (FM) Text of the Recommendation adopted by the “European Radiocommunications Committee“ (ERC): INTRODUCTION In 1991 the European Radiocommunications Committee (ERC) published Report No. 1 on the harmonisation of frequency bands for Radio Lorn1 Area
3、 Networks (RLANs). Subsequently, CEPT Recommendation TIR 10- O1 E (relating to the harmonised radio frequency bands for Wide Band Data Transmission Systems using spread spectrum technology) was published. This Recommendation rmgnises the need to idenw suitable radio spectnim to meet the requirements
4、 of a future European standard for High Performance Radio Local Area Networks (HIPERLANs) being developed by ETSI. After consultation with ETSI, it was established that HIPERLANs required a predictable sharing environment and a band of at least 150 MHz, estimated from the instantaneous data rate of
5、20 Mbits/s per terminal and an average of loo0 MbitdS/floor/hectare. A requirement for two different fiequency bands was foreseen, one offering good fiequency re-use within buildings and the other offering good in-building penetration. It is recognised that the fahire HIPERLAN standard requiring hig
6、her data rates will necessitate a more predictable sharing environment. In cooperation with ETSI and after forther analysis and spectrum engineering studies suitable spectrum was identified in the 5 GHz and the 17 GHz frequency range. CEFT carried out compatibility studies to support the choice of t
7、he frequency bands for RLANs. These studies are m ERC reports Nos. 1 and 8.

12、s and specum investigations have shown that compatibility is possible under certain conditions between RLANs and radiolocation systems operating in the 5 and 17 GHz frequency range; HIPERLANs are intended for indoor use; CEPT Recommendation T/R 22-03 E designates for RLANs (referred to as Cordless L
13、ocal Area Networks) the fiequency range of 59 to 62 GHz enabling high data transfer rates in a small coverage area: recommends that 1. 2. 3. 4. 5. 6. 7. the frequency band 5150 - 5250 MHz be used for HPERLAN equipment on a non-protected and a non- interference basis and that the band 5250 - 5300 MHz
14、 may be used on the same basis, and on a national basis, according to market demand for expansion of the HIPERLAN System fim 1st January 1996. The effective isotropicallyradiated peak envelope power in this band shall not exceed O dBW. This equipment is for indoor use; the frequency band 17.1 - 17.3
15、 GHz be used on a non-protected and non-interference basis for HIPERLAN equipment. The effective isotropically radiated peak envelope power in this band shall not exceed -10 dBW, the other frequency management parameters, which include channel bandwidth and power limits of any emissions outside the
16、designated frequency bands, shall be decided by ERC in consultation with ETSI; in order to provide a predictable sharing environment for HIPERLANs, applications other than those operating in accordance with Article 8 of the RR and HPERLANs should not be permitted in the bands mentioned in Recommends
17、 1 and 2; HIPERLAN equipment and associated antennas must be type approved according to the relevant ETSI Standard and marked “CEPT-HIPERLAN Y” according to the CEPT Recommendation T/R 71-03 E; in the case of HIPERLAN equipment capable of using an external antenna the method of connection between th
