section C: Wirele network allows us to stay away from wires and cables, which can make both services connect with each other using radio waves or infrared technology .The biggest advantage is the convenience of wirele networking.Wirele network frees us from the shackles of a network cable.This means that we can move the laptop from one room to another room and not have to worry about it can not connect to the network.
Nowadays the most popular wirele networking technology is Wi-Fi, Bluetooth technology is also popular in some cases, like connecting two phones .Wi-Fi is designed to improve interoperability based on the IEEE 802.11 standard wirele network between products.At present, most people would confuse Wi-Fi and IEEE 802.11.Even said that Wi-Fi technology for wirele Internet is all.This view is wrong .In fact, Wi-Fi just is one of wirele network technology.
If we want to use the wirele network, we need a wirele router and a wirele device.Wirele router can make the signal on the cable into a wirele signal.Then we will give the wirele signal a name such as one number or a word.So we can find the wirele signal on the device.It will be a list for wirele signal’s name.The number of these signal you scan depend on where you are.When you find your wirele signal and connect it means you have build a wirele local aero network.
