Campus Area Network
A campus area network (CAN) is a computer network that interconnects a few LAN’s (Local Area Networks) throughout a limited geographical area. This area in this case is a university campus, a corporate campus, or a military base. It could be considered a metropolitan area network that is specific to a campus setting. A campus area network is larger than a local area network but smaller than a wide area network. Campus area network may link a variety of campus buildings including departments, the university library and student halls of residence.
In a campus area network, the buildings of a university or corporate campus are interconnected using the same types of hardware and networking technologies that one would use in a LAN. In addition, all of the components, including switches, routers, and cabling, as well as wireless connection points, are owned and maintained by the organization.
University campuses
In the case of using campus area network at a college or university, there is interconnected a variety of campus buildings, including administrative buildings, academic buildings, university libraries, campus or student centers, residence halls, gymnasiums, and other outlying structures, like conference centers, technology centers, and training institutes.
The campus area network is in this case provided wireless. There has to be access points called Hot spots.
Hot spot
A Hot-spot, or Hot spot or HotSpot is a venue that offers internet access over a wireless LAN.

The public can use a laptop, WiFi phone, or other suitable portable device to access the wireless connection (usually Wi-Fi) provided. Of the estimated 150 million laptops, 14 million PDAs, and other emerging Wi-Fi devices sold per year for the last few years, most include the Wi-Fi feature.
For venues that have broadband Internet access, offering wireless access is as simple as purchasing one AP, in conjunction with a router and connecting the AP to the Internet connection. A single wireless router combining these functions may suffice.
Hotspots can be also often placed at restaurants, train stations, airports, military bases, libraries, hotels, hospitals, coffee shops, bookstores, fuel stations, department stores, supermarkets, RV parks and campgrounds and other public places. Free and commercial hotspots can be found through websites such as Free-hotspot.com.
These public Hotspots are, therefore, divided into free and commercial hotspots.
Free Wi-Fi Hotspots
These free wi-fi Hotspots are built-up only by using a Wi-Fi router. Private users of wireless routers can turn off their authentication requirements, thus opening their connection, intentionally or not, for sharing by anyone in range. The disadvantage is that access to the router cannot be controlled.

Commercial hotspots
Many services provide payment services to hotspot providers, for a monthly fee or commission from the end-user income. Major airports and business hotels are more likely to charge for service. Most hotels provide free service to guests; and increasingly small airports and airline lounges offer free service.
