- Abstract
- In Korea, 2.3GHz frequency band will be allocated for a new mobile data service called the portable internet service. So, it is important to investigate the effect of the adjacent channel interference caused by the portable internet service on the conventional WLAN. In this paper, we evaluate the effect of adjacent channel interference from portable internet service on the conventional WLAN, taking into account the nonlineary of RF components. We employed the polynomial based model for the amplifiers and confirmed its spectrum spreading phenomenon due to their nonlinearity. Also we implemented the physical layer of 802.11b and portable internet service system, evaluated the interference effects of the portable internet service with the varying width of the guard band and relative power between the two data services.
