What is a wireless network BBC Bitesize?
A wireless network uses wireless Wi-Fi signals to connect nodes . Wi-Fi signals use radio frequencies in the 2.4 gigahertz (GHz) and 5 GHz wavebands. Each node has a radio transceiver , which allows it to connect to a wireless access point (WAP) .
Why is wireless better than wired?
Speed: Modern Ethernet wired networks are capable of 5 Gbps data transmission. With the addition of Gigabit Ethernet routers to the wired network, their speeds have consistently increased. On the other hand, wireless networks are prone to signal buffer, which is due to low data transfer speeds and data packet losses.
What is difference between wired and wireless?
A wired network employs wires to link devices to the Internet or another network, such as laptops or desktop PCs. (b) Wireless Network: “Wireless” means without wire, media that is made up of electromagnetic waves (EM Waves) or infrared waves. Antennas or sensors will be present on all wireless devices.
What is Wi-Fi ks3?
Wireless internet access Wi-Fi enables computers, mobile devices, games consoles and other devices to connect to the internet wirelessly. It makes it easier than ever to stay connected to the internet wherever you are, eg on a train or in a café.
What do you know about wireless technology?
Wireless technology provides the ability to communicate between two or more entities over distances without the use of wires or cables of any sort. This includes communications using radio frequency (RF) as well as infrared (IR) waves .
What are the benefits of wireless technology?

Why do we need wireless network?
Increased Mobility: Wireless networks allow mobile users to access real-time information so they can roam around your company’s space without getting disconnected from the network. This increases teamwork and productivity company-wide that is not possible with traditional networks.
What is Wi-Fi GCSE?
Wi-fi is a trademarked name for the IEEE 802.11 standard. It is a medium range wireless technology used to connect devices together. Wi-fi uses radio waves to provide a connection to the internet. The radio waves are transmitted by a Wi-fi Access Point (WAP) that normally has a wired connection to the internet.
What is dial up BBC Bitesize?
Dial-up. A dial-up modem converts digital signals from a computer to analogue signals that are then sent down the telephone line. A modem on the other end converts the analogue signal back to a digital signal the computer can understand.
What is Wi-Fi technology?
It is a medium range wireless technology used to connect devices together. Wi-fi uses radio waves to provide a connection to the internet. The radio waves are transmitted by a Wi-fi Access Point (WAP) that normally has a wired connection to the internet.
How does a wireless connection work?
A wireless connection uses radio signals to send data across networks. The wireless adapter converts the data into a radio signal and the wireless receiver decodes it so that the computer can understand it.
How do open wireless networks affect people’s daily lives?
These issues increasingly affect people’s daily lives. Anyone can connect to an open wireless network if they are in range of the signal. The boundary of the network is not set and does not stop when it reaches the walls of a home or business. No physical connection is needed, which makes it more difficult to see who is connected to the network.
How does weather affect Wi-Fi and Bluetooth?
Wi-fi signal can be affected by adverse weather conditions. Water droplets absorb the 2.4 Ghz radio frequency and partially block the signal (however, most WAPs are located indoors) Bluetooth communicates using radio frequencies and requires no physical cable connections.
