Wi-Fi Multi-Cache

Many devices can use WiFi, e.g. personal computers, video-game consoles,smartphones, digital cameras, tablet computers and digital audio players. These can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (66 feet) indoors and a greater range outdoors (unless the Doc has made some modifications to it). Hotspot coverage can be as small as a single room with walls that block radio waves, or as large as many square kilometres achieved by using multiple overlapping access points. If you do not have access to a Wi-Fi ready device you can use this alternative method. N33 47.630 W89 46.106.
