However, the wireless fidelity signal is also provided by the wired network, such as ADSL at home and cell broadband. As long as a wireless router is connected, the wired signal can be converted into wireless fidelity signal. In many developed countries, cities are covered with wireless fidelity signals provided by governments or large companies for residents to use. In China, many places have implemented wireless urban projects to promote this technology. In the pilot cities where 4G licenses are not issued, many places use 4G to wireless fidelity for citizens to try.
