 | Several of our readers have commented that 802.11n based networks seem to do a better job than older forms of Wi-Fi in communicating through walls. But networking experts know that 802.11n signals at a higher frequency (5 GHz) than 802.11b/g and thus is actually technically worse at penetrating obstructions. Why the difference of opinion here? | |
What Is MIMO?
Unlike older Wi-Fi, 802.11n takes advantage of multiple radios and MIMO technology which can in some cases result in better connectivity due to different angles and reflections of wireless signals. If you see 802.11n doing a better job communicating through walls than some 802.11b/g network, MIMO is probably the reason why.

How to Determine Wi-Fi Signal Strength
The performance of a WiFi wireless network connection depends in part on signal strength. Between a computer and access point, the wireless signal strength in each direction determines the total amount of network bandwidth available along that connection.

Is It Legal to Use Open Access Wi-Fi Networks?
Wi-Fi wireless technology simplifies the sharing of network connections between multiple computers and people. Even if you don't subscribe to Internet service, you can log on to public hotspots or to a neighbor's wireless access point to get online. However, using someone else's Internet service isn't always a good idea. It may even be illegal.
