Bluetooth voice and data performance in 802.11 DS WLAN environment

چکیده
In this document, the impact of a 20dBm 802.11 Direct-Sequence WLAN system on a 0dBm Bluetooth link is studied. A typical office environment is assumed with a small number of WLAN access points and a large number of WLAN terminals. The study differentiates between the impact on the Bluetooth data link and the impact on the Bluetooth voice link. Results show that a Bluetooth voice link is disturbed in less than 1% of the cases when the Bluetooth operating distance remains below 2m. If the operating distance increases to 10m, the probability of disturbance increases to 8%. For the Bluetooth data link, a throughput reduction of more than 10% occurs with 24% probability at an operating distance of 10m. Because of the limited frequency overlap of the WLAN and Bluetooth systems, the throughput reduction in the Bluetooth system can never exceed 22%.

Performance of IEEE 802.11 WLANs in a Bluetooth environment
Abstract—Coexistence of different wireless systems that share the same frequency band is becoming one of the most challenging issue due to the wide-spread popularity of WLANs and to the rapid development of shortrange radio systems. In this paper we consider WLANs based on the IEEE 802.11 standard and a short-range radio system based on Bluetooth specifications, which operate in the 2.4 GHz ISM...

Along with the widespread use of the Internet has come a considerable increase in the variety of applications being tried out, one of the most promising of which is packet telephony. Meanwhile, with the spread of the wireless local area network (WLAN) environment, there is growing demand for support for real-time traffic over WLAN. In this paper, we propose a modified MAC protocol that supports...
متن کاملAn Architecture for Integrating UMTS and 802.11 WLAN Networks
Cellular networks, e.g. UMTS, provide voice and data services to mobile users. In hot spots where users need high speed data services operators can deploy low-cost high-speed WLANs, e.g. 802.11, to cover hot-spots. This paper proposes a possible architecture of integrating UMTS and 802.11 WLAN. The architecture allows a mobile node to maintain data (PS) connection through WLAN and voice (CS) co...

IEEE 802.11 and Bluetooth, these two operating in the unlicensed 2.4 GHz frequency band are becoming more and more popular in the mobile computing world. The number of devices equipped with IEEE 802.11 and Bluetooth is growing drastically. Result is the number of co-located devices, say within 10 meters, grown to a limit, so that it may causes interference issues in the 2.4 GHz radio frequency ...
متن کاملSecurity of Wireless Technologies: IEEE 802.11 Wireless LAN and IEEE 802.15 Bluetooth
Wireless LAN (WLAN) is set of protocols defined by the Institute of Electrical and Electronics Engineers in the IEEE 802.11 standard[2]. This standard is itself made up of a number of substandards, allowing different speeds and technologies. Overall, most of the sub-standards of IEEE 802.11, including WLAN, use the same systems for security with only the latest revisions having any substantial ...
