The Institute of electrical and Electronics Engineers (IEEE) confirmed a new standard, 802.11 g, by combining the two incompatible wireless network 802.11 b standard (go far but not quick) and 802.11 a (go fast but not far off). "G" standard 150-foot range, and a maximum speed of 54 Mbps (as opposed to 11 Mbps that we had with the "b" standard). Among the innovations themselves, 802.11 n adds technology called multiple-input multiple-output (MIMO), a signal processing and smart antenna techniques to transmit multiple streams of data over multiple antenna. This led to five times and made up to about two times in comparison with standard 802.11 g before. All wireless access points in our campus today is consistent with the "n" standard, so you can take advantage of the faster connection. The good news is that 802.11 n is backwards compatible with standard 802.11 b/g. This means that if you have a "b" or "g" cards that you don't need to buy a new wireless card if you are satisfied with the speed of your connection.
