Wireless Network

The term wireless is used to describe telecommunications in which electromagnetic waves carry the signal over part or all the communication path i.e., there’s no need for any cable. In wireless transmission, the medium used is the air through not only electromagnetic signals but also radio and microwave signals. 

Wireless technology started with radio telegraphy using Morse code. When the process of modulation was introduced, it became possible to transmit voices, music and other sounds wirelessly, becoming one of the most important ways of transmission of information from one device to other devices. 
Wireless could also refer to any device that communicates with other devices wirelessly, meaning there is no physical connection between them, which facilitates the communication between people, devices, like smartphones, computers or Bluetooth technology printers and other technologies as well. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing are also sometimes classified as wireless. 

Advantages of Wireless Network

Wireless and mobile networks technologies such as WI-FI, WIMAX, RF, LTE, 4G, are an efficient way to bring broadband not only to mobile devices but also to remote regions. One of the benefits and the most obvious  one of wireless is that the wires stopped to be a problem since you don't need  to worry about plugging and unplugging wires or about getting tangled up.

Another advantage is that with Wireless technologies it became possible to work from everywhere since wireless networks are cheap and easy to set up. At a location, you can access the internet from multiple devices that support WI-FI just by having a router at home or at the office, instead of having to setup LAN. This universal access permitted local services, like restaurants, malls, hotels to offer internet via WI-FI to their customers.

In Twoosk you can find legacy products that you need to maintain the Wireless networks, organized in categories: Connectors, Jumpers, Accessories, Cables.

Best Opportunities In Wireless


There are 4 main types of wireless networks: Wireless Local Area Networks (WLANS), Wireless Personal Area Networks (WPANS), Wireless Metropolitan Area Networks (WMANS) and wireless Wide Area Networks (WWANS). Wireless Local Area Networks (WLANS) - People that are in local areas like a coffee shop or a library, can access internet through WLANS. Wireless Personal Area Networks (WPANS) - On WLANS, two technologies (Infra-Red and Bluetooth) are used to connect personal devices. Wireless Metropolitan Area Networks (WMANS) - This type of wireless network is used in metropolitan areas, for example within a city, between buildings. Wireless Wide Area Networks (WWANS) - This form of wireless network differs from wireless local area network (WLAN) by using mobile telecommunication cellular network technologies such as 2G, 3G, 4G LTE, and 5G to transfer data.
Wireless transmission works this way: radio waves are used in a wireless network just as they are used in televisions, mobile phones, and radios. Communication in a wireless network is very similar to two-way radio communication. First, a computer wireless adapter changes the data into radio signals and then transmits these signals using an antenna and next, a wireless router receives the signal and decodes it. It then sends the information through a wired Ethernet connection to the internet. This procedure also works on the reverse in which the router receives information from the internet and sends it to the computer.
Yes, 5G has already been implemented at Asia, USA and at Europe where are some pilot projects being developed. 5G will be the new generation of mobile broadband however it won’t be like the previous generations. It will coexist with 4G so that when your device drops 5G signal, it will fall back on 4G.
5G will always need fiber, because the quality and the reliability of the wireless network will depend on her, so probably, it will use the FTTx networks that already exist and will need far more extensive line-based fiber systems than required by existing 4G. However, it will need new equipment because it is a new technology with different frequencies.
