Security is also important. Laboratory experiments were performed on various performance points of Wi-Fi 5 GHz IEEE 802.11 n Open four-node point-to-multipoint links. Our study contributes to the performance assessment of this technology, utilizing accessible equipments (V-M200 access points from HP and WPC600N adapters from Linksys). New elaborated results are given and discussed, essentially at OSI levels 4 and 7, from TCP and UDP experiments: TCP throughput versus TCP packet size; jitter and percentage datagram loss versus UDP datagram size. Comparisons are made to correspondent results from Open point-to-point links. Conclusions are taken about the comparative performance of the links. © 2017 Institute of Measurement Science SAS.engIEEE 802.11nOpen Four-node Point-to-Multipoint and Point-to-Point LinksWi-FiWireless Network Laboratory PerformanceWLANconference object10.23919/MEASUREMENT.2017.7983560
