Fixed WiMAX is an emerging and promising broadband wireless access system that is being widely deployed. Fixed WiMAX performance is boasted to outperform competing technologies, but is also doomed to be a short-lived hype. As little or no published material exists about measurements in real life field trials, we sat up a test bed and performed extensive(More)
Radio links for high capacity telecommunication networks have been widely used since many decades. Even with the major transport delivered by fibre optics the usage of radio links is still very high in all part of the network. Gigabit single channel radio links are quite recent and offer an interesting solution for the demanding transport network parts(More)
Wireless network operators often offer wireless broadband services by using different wireless technologies such as WiMAX, WiFi and HSPA. Each wireless technology often uses a separate and stand alone network architecture, and thus operations and management may easily become a complex and expensive task. In this paper we present the design and(More)
Fade duration statistics are important in describing the dynamics of expected quality when designing and using millimetre wireless links. The paper presents several years of measured duration statistics for four terrestrial line-of-sight links at 42.1 and 83.5 GHz in the Oslo-region, Norway. The measured durations are compared with models. Relatively good(More)
It is well-known that the throughput of wireless mesh networks without frequency re-use decreases as O(1/N), where N is the number of nodes in the network. In this paper we build on this result and obtain expressions for calculating the throughput in IEEE 802.11-based mesh networks without interference. Both expressions for single-frequency and(More)
