30 Αυγ 2024 · Bridge and Repeater are two improtant connectivity devices in computer network. Both devices ensure seamless communication between the segments of a network. These devices are a type of network extender, but they operate at different layers in the OSI and serve different purposes.
When it comes to wireless devices, many of them fit into the computer-peripheral category. A computer peripheral is a device made for a computer, but it's not a part of the computer. A wireless printer is an example of a wireless computer peripheral.
18 Μαΐ 2020 · In this section, we discuss two prominent wireless technologies: Wi-Fi (more formally known as 802.11), and Bluetooth. The next section discusses cellular networks in the context of ISP access services.
19 Νοε 2020 · The most popular Wi-Fi devices at the time of this writing, IEEE802.11n and IEEE 802.11ac, use MIMO-OFDM technology with three transmitters and two receiver antennas, shown in Fig. 6. The OFDM signal has 64 sub-carriers, using 52 of these carriers for communication data.
Bluetooth defines a local point-to-point mechanism that allows computer peripherals to communicate without a cable physically connecting the devices. Zigbee creates a wireless mesh network that can be used to route data, such as sensor readings, between low-powered devices.
7 Νοε 2023 · Wireless Communication: The most obvious characteristic of a wireless network is that it uses wireless communication technology to connect devices. Data is transmitted over the airwaves using radio frequencies, allowing for untethered connectivity.
6 ημέρες πριν · Wi-Fi is a networking technology that uses radio waves to allow high-speed data transfer over short distances. It is commonly used to provide wireless broadband Internet access for a variety of devices.
