This paper deals with performance measurements in 802.11g Wireless Multi-Hop Net-

works at different locations. After an introduction to 802.11g Wireless LANs and

Wireless Multi-Hop Networks, the testing environment consisting of hardware, soft-

ware, configuration, and three different locations is described. Before test series for the

actual measurements are defined, carried out reference tests provide reference perfor-

mance data and prove that the used hardware is suitable for testing Wireless Multi-Hop

Networks. Then the results of the measurements are discussed which show the influ-

ence of multiple hops on throughput and latency for single and multi channel Multi-Hop

Networks in indoor, outdoor, and urban environment. Finally, an outlook to further

tests and improvements of Wireless Multi-Hop Networks is given.
