"Wireless networking technology is evolving rather rapidly with 802.11n Draft 2 Wi-Fi currently being the standard of choice when going out to the store and picking up the latest router. If you are in the right place, you also have the choice of connecting your devices to the outside world via 3G or faster HSDPA 3.5G and beyond. If you are really in the right place, you might have the option to use WiMAX. Wireless technology is a wonderful technology and it is really pushing radio to extreme limits.
What happens, though, when wireless isn’t appropriate for your home or office? Maybe wireless isn’t an option due to other devices interfering or the range you are trying to work with is just pushing it too much. Of course, there is the CAT5e or CAT6 networking cable option for local Gigabit networking, but if your house or office isn’t new and not connected up with this cabling, it can be rather messy having cables running around all over your floors."
