Co-existence of Bluetooth and IEEE 802.11b WLANs: results from a radio network testbed

Wireless Technology in Industrial Networks

“…Note that throughput values can decrease even more when additionally using higher layer protocols. Measurements for the throughput of TCP/IP traffic in Ethernet packets for the IEEE 802.11b specification, for example, have returned results of a 5-Mb/s maximum throughput [101], [102]. IEEE 802.11 employs immediate MAC-layer acknowledgment and retransmissions.…”

“…The interference between BT and IEEE 802.11b has been investigated extensively [101], [102], [113]- [117]. In [118], it was found that IEEE 802.11b requires a carrier-to-interference ratio (CIR) of about 10 dB to cope with a (narrow-band) interference in its (wide) passband.…”

“…If a BT system and an IEEE 802.11b system are so close together that the 20-dB higher transmition power of IEEE 802.11b blocks the BT receivers from receiving (when antennas are less than 20-30 cm apart), then only methods such as a joint scheduler can help to enable a fair coexistence [102].…”

SystemC modelling of wireless communication channel

“…The interference between the great number of widely used standards using same 2.4 GHz band must be considered in the design of a wireless network. Several work has been developed on the interference problem between WiFi, ZigBee, WirelessUSB and Bluetooth in the literature [8][9][10][11][12]. In [8] the interference between Bluetooth and WiFi is evaluated at packet-level by experiments.…”

Co-existence of CSMA/CA and Bluetooth

“…In [1], simulation results are presented at bit level, highlighting the effect of IEEE 802.1 lb on BT. The authors present results from a co-existence testbed in [2], [3], where the main aim is to validate the simulation models using the measurements from a real life testbed. The BT packet error probability due to IEEE 802.1 lb interference is given in [4] using a very simple physical layer analytical model.…”
