What is Wireless Access Points
In the LAN (Wired Network) each client connects to a switch. The switch is the center 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....
Wireless Home Router Exclusive Explanation
A Wireless home router is a device that communicates between the internet and the devices in your home that connect to the internet. It routes traffic between the devices and the internet. Selecting the right kind of router for your home is very important. A wireless home router usually serves as: A wireless router server...
Wireless Network Interface Card (WNIC) – Exclusive Details (Updated 2026)
Over 80% of global internet users rely on wireless connections daily, according to a 2026 Statista report, with Wireless Network Interface Cards (WNICs) powering that seamless access. These compact hardware components connect devices to wireless networks, enabling everything from streaming to remote work. This exclusive deep dive uncovers the intricacies of WNICs, delivering hard-to-find details...
Comparison Between WLAN and LAN – Exclusive Explanation
A WLAN allows devices to connect and communicate without using wires or cables. However, 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 primary 802 standards are 802.3 Ethernet and 802.11...
IEEE 802.11 Standards Exclusive Introduction
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 Exclusive
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 for radio broadcasting, and others are used for television broadcasting....
Wireless Technologies in 2025: What’s New, What’s Changed, and What’s Next
Wireless technologies refer to technology that makes it possible to communicate over a distance without using wires or any other conductors. We can use wireless technologies for both long and short distances. Wireless technologies networks are based on electromagnetic waves, such as radio frequencies (RF), infrared (IR), satellites, etc. Remember when Wi-Fi was a luxury...
What is Wireless? Exclusive Introduction
Wireless Communication is the fastest-growing and most vibrant technological area in the communication field. It can provide client mobility, the ability to connect from any location and at any time, and the ability to roam while staying connected. It is the technique of transmitting information from one point to another without using any connection like...
How to configure EtherChannel?
In this lesson, I am going to configure EtherChannel. EtherChannel in 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...
EtherChannel Protocols: PAgP and LACP – Master Link Aggregation in 2026
EtherChannel is used to bundle physical links into a single logical link. We can bundle a maximum of 8 physical links into one logical link. When physical links are bundled into a single logical link, the STP only sees one and cannot block anything. Two types of protocols are used for EtherChannel: Port Aggregation Protocol...
