Types of OSPF Network – Introduction
OSPF is a dynamic link-state routing protocol replacing the distance vector routing protocol, RIP. However, OSPF has important advantages over RIP. OSPF offers faster convergence and scales to much larger network implementations. The OSPF defines five types of OSPF networks: Point-to-point—A point–to–point network is when two routers are interconnected over a common link without any...
Introduction to Wireless Antennas
Wireless antennas are elements of a radio communications system that radiate and/or collect radiofrequency energy. They are usually connected using a low-loss coaxial cable to a power amplifier, splitter, and filter or directly to wireless devices. For outdoor usage, wireless antennas are often attached via mounting clamps to a mast or the side of a...
Wireless Deployment Solutions – Exclusive Explanation
Wireless Deployment is depending on the requirement of an organization. Some organizations want coverage for small are while other needed coverage for a large area. Cisco offers deployment both for small and large organizations. Small Wireless Deployment For small wireless deployment requirements, Cisco offers autonomous AP solutions. The different types of autonomous APs are the...
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....

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....
