A study on the performance of Bluetooth and IEEE 802.11b coexistence

Abstract There is potential for interference between IEEE 802.11 wireless local area networks (WLANs) and Bluetooth (BT) piconets as both of them are operating in the 2.4 GHz Industrial, Scientific, and Medical (ISM) radio band. With IEEE 802.11b and Bluetooth growing popular, a lot of research is being conducted to improve the coexistence of both technologies in the ISM band. Current research has not given much attention in studying the effect of multiple Bluetooth piconet (scatternet) on an IEEE 802.11b WLAN network and vice versa. This paper presents the analysis of performance degradation in the IEEE 802.11b WLAN due to the presence of Bluetooth scatternet, using a simulation model. The OPNET Modeler® tool from OPNET, Inc. along with SuiteTooth model was used to model the components of Bluetooth and IEEE802.11b WLAN. The results of this simulation demonstrated that Bluetooth scatternet has a severe impact on the performance of WLAN in comparison to the impact that of WLAN on Bluetooth.


Since the beginning of the 21st century, two innovations in the wireless radio technology have taken hold of the markets and captured attention of the public; Bluetooth Wireless Personal Area Networks (WPAN) and IEEE802.11b Wireless Local Area Networks (WLAN). These wireless communication technologies showed great promise in transforming how people work and communicate with each other.

Bluetooth and IEEE 802.11 standards utilise the same 2.4GHz Industrial, Scientific, and Medical (ISM) frequency band. However, as both technologies operate in the same frequency band, an issue of growing concern is the coexistence of these technologies in the same environment.

“Coexistence” is defined as the ability for multiple protocols to operate in the same frequency band without severe degradation to either’s operation. Bacuse of the rapid growth of these devices, this issue of coexistence has recently become a significant topic of analysis and discussion throughout the industry. The most important factor that is likely to affect the coexistence of these technologies operating in the same environment is interference.

Numerous studies of the interference in the 2.4 GHz ISM band range have been carried out with different focus areas. Several publications have addressed the issue of interference both theoretically and by simulation.

In the early stage of Bluetooth specification development, Ennis1 studied the effect of interference based on a mathematical model rather than actual usage of models. Haartsen and Zurbes2 combined analytical studies with simulation to provide an insight on the impact of 802.11 Direct-Sequence WLAN systems on Bluetooth data and voice links. Punnoose et al.3 presented experimental results for the performance degradation of Bluetooth and IEEE 802.11b Direct Sequence Spread Spectrum (DSSS) devices due to mutual interference. These experiments were conducted in a large outdoor open space and also in a lab environment which focused on characterizing the performance of 802.11b devices in the presence of Bluetooth interference.
