Abstract

Customer demand for infotainment systems has garnered great attention from car manufacturers. System features have become a decisive factor when choosing among car models. As consumers become more dependent on their portable electronic devices (e.g., mobile phones, tablets), they expect to have seamless integration of their devices inside their cars. This allows them to use the same features supported by their phones in the cars. Car manufacturers aim to make their infotainment systems user-friendly. A key factor to achieve this goal is facilitating a wireless connection between mobile phones and car computers. IEEE 802.11 systems are the most popular candidate to provide high data rate connections utilizing the unlicensed industrial, scientific and medical (ISM) radio band. However, due to the limited available spectrum and the high density of devices inside the car, the achieved throughput could be strongly affected by interference and coexistence challenges. Furthermore, strong interference between the networks in different cars plays a crucial role in the automotive domain. This paper highlights the interference problem between IEEE 802.11 systems in cars. Two solutions in the 802.11n standard, namely transmission power control (TPC) and multiple input multiple output (MIMO) techniques, are discussed. Results show that both techniques could improve system performance. Transmission power control is essential to control radiation to surrounding environment.
