Checkpoint: Site Survey Benefits I am writing in regards to the wireless network project. It is important that we do a site survey before we attempt to install any wireless network. The first thing that we need to do is conduct the site survey‚ this will let us know if there are any other wireless networks currently in the area. This needs to be known so that we can figure out which band we will need so that we can minimize any interference and give the best performance possible. By us doing

A Technical Comparison of 802.11n to 802.11g A Technical Comparison of 802.11n to 802.11g Abstract 802.11n was developed to address issues of distance and speed. These were issues with wireless g and especially big issues with legacy devices that were used previously. Wireless N devices allow for a wider range by using multiple-input multiple-out and multiplexing allowing more data to be sent at a given time than before in previous a/g devices. It also allows for better communication between

PCM CODING/COMPANDING Q1. a)i) The process of quantisation introduces an error or noise component into the quantised signal. Derive an equation for the mean-squared quantisation error in terms of the quantization interval ‘a’. ii) Hence show that the peak signal-to-quantisation noise ratio (SQNR) is SQNR = ( 6n + 4.8 ) dB Where 2 n is the number of quantisation levels. b)i) Linear quantisation is used prior to binary PCM encoding of an analogue baseband signal which has
