“…where: 12 A similar analysis may be carried out for IEEE 802.11g system for example taking into account the method of [27]. On the other hand FER determination method for 802.11b system presented in this study can be easily adapted for 802.11g network on the basis of bit error rate and time-frequency dependences proposed for example in [28].…”

Standard Bluetooth does not precisely determine the rules of forming Bluetooth scatternets. So far many interesting scatternet forming algorithms have been proposed. This publication tries to assess selected Bluetooth networks forming algorithms taking into account a few key parameters. In particular, the aspect of impact of topology created in a given way, has been researched taking into account potential interferences inside the scatternet (interferences between piconets) and on other technologies working in ISM band (that is IEEE 802.11b).

“…As all this devices operate in the same frequency band, interference from other devices becomes a major issue whenever they operate nearby. In our previous work [19] and from literature performance of WLAN in presence of Bluetooth, Zigbee interference [5][6][7][8][9][10][11][12][13][14] can be found.…”

In this paper we give the performance of MQAM OFDM based WLAN in presence of single and multiple channels Zigbee interference. An analytical model for getting symbol error rate (SER) in presence of single and multiple channel Zigbee interference in AWGN and Rayleigh fading channel for MQAM OFDM system is given. Simulation results are compared with analytical symbol error rate (SER) of the MQAM-OFDM system. For analysis we have modeled the Zigbee interference using the power spectral density (PSD) of OQPSK modulation and finding the average interference power for each sub-carrier of the OFDM system. Then we have averaged the SER over all WLAN sub-carriers. Simulations closely match with the analytical models. It is seen from simulation and analytical results that performance of WLAN is severely affected by Zigbee interference. Symbol error rate (SER) for 16QAM and 64QAM OFDM system is of order of 10 -2 for SIR (signal to interference ratio) of 20dB and 30dB respectively in presence of single Zigbee interferer inside the WLAN frequency band for Rayleigh fading channel. For SIR values more than 30dB and 40dB the SER approaches the SER without interference for 16QAM and 64QAM OFDM system respectively.

“…As a result of this difference, and the specified channel structure for WiFi systems, the interference characteristics between co-existent 802.11b and 802.11g systems will be different and this has yet to be studied in detail. Past co-existent interference studies [3], [4] have tended to concentrate on interference between Bluetooth and WiFi or on the tolerance of WiFi systems to interference from sources other than these two types of system [5], [6]. However, interference between Manuscript WiFi systems has begun to be studied in more detail, and recent work [7] has reported how 802.11b and 802.11g networks are affected by interference from their own type of system.…”

The main aim of this paper is to provide insights into the performance degradation caused by interference between coexistent 802.11b and 802.11g WiFi systems operating in environments where channel overlap cannot be excluded. The fundamental differences between their interference characteristics are overviewed and analysed, and it is shown that channel overlap degrades their performance by differing amounts. It is also shown that for similar interference levels this degradation is slightly worse than for systems that are exclusively 802.11b but slightly better than for ones that are exclusively 802.11g. Overall, it is shown that for WiFi systems operating in environments where channel overlap exists, increasing the channel separation is generally of greater benefit for 802.11b than 802.11g.
