WiFi Mobile Phone
A Wi-Fi mobile phone is a mobile phone which uses a brand of wireless communication system called Wi-Fi. The regular cellular phone and a Wi-Fi mobile phone share several similarities. The Wi-Fi mobile phone is the same as any other mobile phone in terms of physical structure and functions. However, unlike a cellular phone, which commonly operates at 824 MHz to 894 MHz, a Wi-Fi mobile phone operates at a different frequency band. A Wi-Fi mobile phone uses 2.4 GHz and 5 GHz, although a newer kind of Wi-Fi mobile phone is able to switch between Wi-Fi and cellular networks.
The basic components of a a Wi-Fi mobile phone include a processor, speaker, microphone, keypad, battery, an LCD screen, antenna, and memory. Like a regular cellular phone, communication through a Wi-Fi mobile phone travels via radio waves. In using a W-Fi mobile phone to place a call, the user simply dials the phone number of the receiving party. If the receiving party is on VoIP service, the user needs to key in the VoIP address. Although a Wi-Fi mobile phone is usually subscribed to a specific Wi-Fi provider, some phones use protocols, such as SIP (Session Initiation Protocol), which anyone with a SIP address can access.
How does a Wi-Fi mobile phone work?
When a person uses a Wi-Fi mobile phone to make a call, he or she needs to dial either a phone number or a VoIP address in order to have the call routed to the receiving party. The Wi-Fi mobile phone then converts the contact details into data packets. These data packets go through radio waves and into a wireless receiver. The wireless receiver transfers the data packets to the Internet and into a call processor. When the receiving party picks up the call, the conversation is activated. Voice is also transmitted through the Wi-Fi mobile phone as packets of data.
Why do you need a Wi-Fi mobile phone?
Wi-Fi facilitates wireless information accessibility and communication. With Wi-Fi, there is no need for switches, cables, and connectors. A Wi-Fi mobile phone has wireless access to the Internet and a variety of Internet-based applications, such as streaming, within the Wi-Fi hotspot. Wi-Fi hotspots are those areas within a Wi-Fi-enabled perimeter. Because some Wi-Fi mobile phones can switch from Wi-Fi to cellular network and vice versa, you can use the services of both systems. Wi-Fi is now more popular, as Wi-Fi hotspots are offered as value-added service in airports, coffee shops, hotels, and other establishments in order to draw in more clients.
