Subsequently, CEPT Re

3、commendation T/R 10-01 E (relating to the harmonized radio frequency bands for Wide Band Data Transmission Systems using spread-spectrum technology) was published. This Recommendation recognizes the need to identify suitable radio spectrum to meet the requirements of a future European standard for H

4、igh Performance European Radio Local Area Networks (HIPERLANs) being developed by ETSI. After consultation with ETSI, it was established that HJPERLANs required a predictable sharing environment and a band of at least 150 MHz, estimated from the instantaneous data rate of 20 Mbits/s per terminal and

5、 an average of 1000 Mbits/s/floorhectare. A requirement for two different frequency bands was foreseen, one offering good frequen- cy re-use within buildings and the other offering good in-building penetration. It is recognized that the future HIPERLA“ standard requiring higher data rates will neces

6、sitate a more predictable sharing environment. In cooperation with ETSI and after further analysis and spectrum engineering studies, suitable spectrum was identified in the 5 GHz and the 17 GHz frequency range. CEPT carried out compatibility studies to support the choice of the frequency bands for R

7、LANs. These studies are in ERC Reports Nos. 1 and 8.

12、band 5150-5250 MHz by the aero- nautical community, b) compatibility studies and spectrum investigations have shown that compatibility is possible under certain conditions between RLANs and radiolocation systems operating in the 5 and 17 GHz frequency range, c) HIPERLANs are intended for indoor use,

13、 d) CEPT Recommendation T/R 22-03 E designates for RLANs (referred to as Cordless Local Area Networks) the fre- quency range of 59 to 62 GHz enabling high data transfer rates in a small coverage area, recommends that 1. the frequency band 5150-5250 MHz be used for HIPERLANs on a non-protected and a

14、non-interference basis and that the band 5250-5300 MHz may be used on the same basis, and on a national basis, according to market demand for expansion of the HPERLAN System from 1st January 1996. The effective isotropically radiated peak envelope power in this band shall not exceed O dBW, 2. the fr

17、le 8 of the RR and HIPERLANs should not be permitted in the bands mentioned in Recom- mends 1 and 2, 6. HIPERLANs must be type approved according to the ETSI Standard xxx and marked “CEPT-HIPERLAN Y” according to the Recommendation T/R 71-03 E, 7. CEPT Member countries shall not require an individual licence for the use of HIPERLANs.” Edition of March 1, 1993
