lyst firm Point Topic revealed that there were a total of 484 million fixed-broadband subscribers at the end of the first quarter of 2010. The report covers only broadband access over cabling and fixed, point-to-point wireless services. China had the most subscribers at 112.6 million. The country with the second most was the United States, with 87 million subscribers. These findings were reported in a June 16, 2010 ZDNET article by Victoria Ho, titled "China Adds More Broadband Lines." Many people in less-developed parts of the world access the Internet primarily over mobile services. This is because dedicated Internet access over landline networks is frequently either not available or more costly than mobile services in these areas. In addition, electricity is often expensive. In the Philippines, both ISP-delivered dedicated Internet access and electricity are too costly for most citizens. Thus, mobile services are attractive as electricity is only required for charging laptops, tablet computers, and other devices that are equipped with mobile capabilities. Moreover, a single device can be used to make calls and to access sites such as Facebook. While current mobile networks support broadband services, they're slower than those over most wireline networks. However, new technologies and upgrades to exist- ing technologies are expected to vastly improve Internet access on mobile networks and spur adoption of mobile broadband. Fourth-generation (4G), high-speed mobile protocols such as Worldwide Interoperability for Microwave Access (WiMAX) and Long-Term Evolution (LTE) are in various stages of development, testing, and imple- mentation. In addition to fourth-generation mobile services, worldwide mobile carriers are upgrading existing third-generation networks. There is large growth potential for higher-speed broadband access in Latin Amer- ica, Africa, and even China, where, according to a report by the International Telecom- munications Union (ITU), as of June 2010, only 7.7 out of every 100 inhabitants had fixed
