WLAN stands for Wireless Local Area Network and it’s the internet network that is attached to the cell phones wirelessly. When there is such a network is available in the neighborhood, you just need to turn on the feature on your cell phone and it will connect with the WLAN and will start sending and receiving data buckets. WLAN not only enables us to send emails, multimedia messages but video calling is also available with WLAN.
NFC stands for Near Field Communication and it’s actually a broader form of Bluetooth but used for different purposes. With this feature in your cell phone, you don’t need to carry any kids of credit cards, bus passes or anything like that but you can just tap your cell phone on a NFC terminal and it will fetch the data from your cell phone and recognize you. This is actually the future of payment processes without having any money or credit cards in your wallet.
Bluetooth is kind of small range local network established between two cell phones. This network is not like an internet connection or WLAN but serves the same purpose as you can transfer photos, songs, videos and other types of data files from one cell phone to other via Bluetooth. It’s actually latest form or infrared presented in older cell phones.
It stands for Global Positioning System and it’s a navigation system that is used in cell phones. It includes the cell phones, a network and the satellites in the space around the world. This feature of navigation allows us use the satellites for various purposes i.e. finding travelling route to a destination, finding restaurants and gas stations in your way etc. on one hand it benefits the cell phone users where on the other hand, it allows the law enforcement agencies to track the location of cell phones with GPS in case of an emergency.
Navigation is a part of GPS that allows individual users or professional departments to monitor the position, movement and route information of a vehicle on the road, air or in water. In cell phones, navigation is used to find out the routes to different locations for travelling purposes. For example, you want to go to a specific address in another city but you don’t know the route so you enter yours and your destination address in the navigation tool and it displays the shortest route between these two points. It is widely used by cell phone users mostly for travelling purposes.
This is again a part of GPS and it is the feature in a cell phone that allows the users to find out their position on earth defining in longitude and latitude. On the other hand, it also allows the law enforcement departments to find the location or position of a cell phone in case of an emergency. These days’ parents install positioning feature in the cell phone of their children so that they can track the movements and current position of their children anytime they want
USB stands for Universal Serial Bus and it’s a port that is used in various devices i.e. mobiles and computers to attach other devices and transfer data from one device to other. In latest form, all cell phones are equipped with USB feature that allows the user to attach the cell phone to a computer or a laptop via USB cable that is faster and easier to use. USB 2.0 was the older form of this feature and now cell phone manufacturers use USB 3.0 which is faster, quicker and more efficient.
USB is usually used for two purposes in a cell phone; mass storage and charging. If you want to transfer data files in between your cell phone and your computer, you can either use Bluetooth or infrared feature but that is very slow. So, a as a solution you attach your cell phone to the computer via USB port and this way you can transfer data files from cell phone to your computer or vice versa. Second feature of USB port is to charge the cell phone via computer. As compared to mass storage feature, USB charging is used more frequent and those who work on a computer desk just plug in their cell phones in USB ports on computer and charge their devices without wall mounted sockets.
