Comparison between wired Ethernet vs. wireless 802.11a/b/g/n:

1. Bandwidth is important to hospital personnel to quickly transfer large medical imaging data, and wired Ethernet comes out ahead with faster bandwidth speeds. Today many new deployments are implementing 802.3z and 802.3ab Gigabit Ethernet at 1000 Mbps for client access, whereas the latest technology in wireless (802.11n) offers speeds of 150 Mbps, assuming proximity to the signal and little or no interference. In very rare cases where four spatial streams are used along with a 40 MHz-wide channel, 802.11n can go up to a data rate of 600 Mbps, which is ...
