“…Procedures of Detect And Avoid (DAA) are presented in [10]. Such procedures consider the situation where UWB devices can detect a WiMAX terminal in its proximity and, thus, adapt their transmission in order to interfere as less as possible the WiMAX victim.…”

This paper presents some experimental results about the robustness of a WiMAX system against interfering signals. In particular, this work presents a WiMAX performance comparison when two different types of interfering signals were generated: a continuous wave and a rectangular pulsed wave. Both of them were tuned at the same working frequency of the WiMAX system (i.e. 2.55 GHz). The former is typical of some attackers or dud devices, the latter, instead, is very similar to the signals generated by radars. In this work IP throughput performance and the WIT (Voice over IP) perceived Quality of Service (QoS) were evaluated, when one of the two considered signals interfered the Base Station (BS) or the Costumer Premise Equipment (CPE). The experimental results point out that the continuous wave was more critical than the pulsed one for the WiMAX system; in some situation it caused the complete disconnection of the CPE from the BS or the BS outage

“…However, the effect of UWB interference on WiMAX receivers is studied by many researchers, in [7] (2007), the authors evaluated the impact of UWB transmissions on the performance of a WiMAX receiver. They presented a noncooperative detect and avoid (DAA) procedure to mitigate the UWB interference to WiMAX.…”

In this paper, we evaluate the performance of WiMAX downlink system in vicinity of UWB system. The study is achieved via simulating a scenario of an office building which utilizes from both WiMAX and UWB appliances. From the simulation results, we found that WiMAX system is largely affected by the UWB interference. However, in order to overcome the interference problem and achieve reasonable BER (Bit Error Rate) of 10-4, we found that it is very necessary to raise the WiMAX transmitted power in relative to that of UWB interferer. So, the minimum requirements for WiMAX system to overcome UWB interference are stated here in this work.
