Wireless Internet Access Points At home, work, school, and in many public locations, people connect wirelessly to the Internet through a wireless Internet access point using mobile computers, smart phones, handheld game consoles, or other devices. Users access wireless Internet access points with computers or devices that have the necessary built-in wireless capability or the appropriate wireless network card, PC Card, ExpressCard module, or USB network adapter (Figure 8-4). Two types of wireless Internet access points are hot spots and mobile wireless networks. A hot spot is a wireless network that provides Internet connections to mobile computers and other devices. Through the hot spot, mobile users check e-mail, browse the Web, and access any service on the Internet. Three hot spot technologies are Wi-Fi, WiMAX, and Bluetooth. Wi-Fi hot spots pro- vide wireless network connections to users in public locations such as airports, train stations, hotels, convention centers, schools, campgrounds, shopping malls, bookstores, libraries, restaurants, and coffee shops. The coverage range for WiMAX hot spots, can be much wider than Wi-Fi; for example, they can cover an entire city. Bluetooth hot spots provide location-based services, such as sending coupons or menus, to users whose enabled devices enter the coverage range. Sections later in this chapter discuss Wi-Fi, WiMAX, and Bluetooth in more detail. Some hot spots provide free Internet access, some charge a per-use fee, and others require users to subscribe to a wireless Internet service provider, to which they pay per access fees, daily fees, or a monthly fee. Per access fees average Php100, daily fees range from Php20 to Php150, and monthly fees range from Php1,000 to Php5,000 for unlimited access, with the higher monthly fee providing greater coverage areas. A mobile wireless network provides users with high-speed Internet connections, as long as they are in the network’s range. A mobile wireless network usually includes most major cities and air- ports. Subscription fees for unlimited monthly Internet access to a mobile wireless network through a cell phone range from Php1,000 to Php3,000. Fees for notebook computer access are higher, ranging from Php1,500 to Php3,500 per month.
