Chapter 4. JDS Networking > Public and Private Hotspots

4.5. Public and Private Hotspots

Outside of the office or home, many stores, restaurants, and other sites now offer wireless access. Some do it free of cost, some (such as hotels) require you to register and pay a daily fee, and some offer a subscription that lets you use their facilities in many different places as you travel. Regardless of the business aspects of wireless networking, all these sites are called hotspots.

Private hotspots can be located in the workplace, or you may have a private group of users who choose to create and share a hotspot.

Community hotspots fall somewhere between the spectrum of public and private. They offer free access, yet use privately owned access points. Public organizations create community hotspots and can be independent or affiliated with a nonprofit organization.

4.5.2. What Do You Need to Join a Hotspot?
