我们比较了IEEE 802.11和ETSI HIPERLANI型两种标准化无线局域网的不同性能指标，并考虑了两个基本的性能限制因素：衰落空气介质的误码率和自组织网络中的站点数量。对于HIPERLAN1，由于更复杂但更复杂的EY-NPMA MAC协议，大多数性能指标对站的数量不敏感。然而，随着误码率的增加，其高开销冗余会导致吞吐量的极大降低。IEEE 802.11中相对简单且开销较低的CSMA/CD协议在较高负载下遭受多次冲突，从而对站的数量产生高敏感性。
We have compared different performance measures of the two standardized WLANs, IEEE 802.11 and ETSI HIPERLAN type 1. Two essential performance-limitation factors have been considered: the BER of the fading air medium and the number of stations in the ad-hoc network. Regarding the HIPERLAN 1, most of the performance measures are insensitive to the number of stations due to the more sophisticated but complex EY-NPMA MAC protocol. However, its high overhead redundancy causes great throughput degradation as the BER is increased. The relatively simple and low overhead CSMA/CD protocol in the IEEE 802.11 suffers from many collisions at higher loads, producing high sensitiveness to the number of stations.
