The best cellphones with WiFi also support tethering which can help you use our mobile phone to share your internet connection with other WiFi enabled devices.
Wi-Fi is a feature available in most modern smartphones. It is based on the hardware of the phone and is carrier independent. It is a mechanism for wirelessly connecting the smartphone to the Internet via a wireless network access point. An access point (or hotspot) has a range of about 20 meters (65 ft) indoors and a greater range outdoors. Hotspots are often found at restaurants, train stations, airports, libraries, hospitals, coffee shops and various other public establishments throughout the US.
The speed of the Wi-Fi connection depends on many factors including:
- The distance between your phone & the wireless router.
- Your broadband speed.
- The capability of your phone hardware.
- The number of devices using the hotspot.
Normally, the download speeds can vary from 1mbps to 8 mbps or more when connected to a broadband router.
Many public and private establishments and educational organizations offer free Wi-Fi access. Commercial Wi-Fi is also available with volume based billing. Here, authentication of the user will be required.
Another feature supported by new smartphones is Wi-Fi tethering. It allows your mobile device to share its Internet connection with other Wi-Fi enabled devices, effectively making your phone a Wi-Fi hotspot. This might be useful when you need to go online from your laptop or PDA or e-book reader and there's no other means of Internet access available. This can also save money if you are using a paid data service on your cell-phone as it eliminates the need of separate hardware/connection for your laptop etc.
