In the LAN (Wired Network) each client connects to a switch. The switch is the centre point for each client to gain access to the network. The wireless Access Points also connects to the switch. Wireless clients discover nearby APs using their wireless NIC. The wireless Access Points are advertising their SSID for the client. Clients […]
A Wireless home router is a device that communicates between the internet and the devices in your home that connects to the internet. It routes traffic between the devices and the internet. The selection of the right kind of router for your home is very important. A wireless home router usually serves as: Access point– […]
To communicate without wire, computers and end devices require a wireless network interface card (WNIC). A wireless network interface card (WNIC) is a network card which connects to a wireless radio-based network. It is just like other NICs, functioning on the Layer 1 and Layer 2 of the OSI Model. It performs the same operation […]
A WLAN allows devices to connect and communicate without using wires or cables. But in the traditional wired LAN devices communicate over Ethernet cables. Both WLAN and LAN share a similar origin. The IEEE has chosen the 802 network standards for LAN/MAN portfolios of computer network architecture. The two main 802 standards are 802.3 Ethernet […]
The IEEE 802.11 WLAN represents the IEEE designation for wireless networking. IEEE 802.11 standard defines how RF in the unlicensed ISM frequency bands is used for the physical layer and the MAC sub-layer of wireless links. Several implementations of the IEEE 802.11 standard has defined by IEEE over the years. All the standards use the […]
Radio frequencies refer to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz. This band is used for communications transmission and broadcasting. Different radio frequencies are useful for different wireless technologies. For example, some frequencies are used to fore radio broadcasting; some frequencies are used for television […]
Wireless technologies refers to technology that makes possible to communicate over a distance without using wires or any other conductors. We can use wireless technology for both long and short distance. Wireless technologies network has based on electromagnetic waves like radio frequencies (RF), infrared (IR), satellite, etc. We can broadly classify wireless technologies as: Wireless […]
Wireless Communication is the fastest growing and most vibrant technological areas in the communication field. It can provide client mobility, the skill to connect from any location and at any time, and the skill to roam while staying connected. It is the technique of transmitting information from one point to other, without using any connection […]
EtherChannel Configuration in the networking has a set of restrictions that state what you can do and what you cannot do. Before configure and establish the EtherChannel, it is important to know the restrictions. Here are some basic restrictions and guidelines on setting up EtherChannel: EtherChannel support– Ethernet channel support on all interfaces must support […]
EtherChannel is used to bundle physical links into a single logical link. We can bundle maximum of 8 physical links into one logical link. When physical links bundled into a single logical link, the STP only sees a single logical link and is not able to block anything. There are two types of the protocol […]
