Wireless Personal area network

What is a WPAN? WPAN standards for Wireless personal area network, it consist of a group of short range communication  devices that work from distance from a few inches to 10m  and can on occasion reach up to a distances of 30m. WPAN are usually designed for  data transmission that do not required high dataContinue reading “Wireless Personal area network”

Wireless Signals

The following information is based on my UNI studies on wireless communication systems. Wireless Signals: All forms of electromagnetic energy- gamma rays, radio waves, even light- travel through space in the forms of waves. These waves are know as electromagnetic waves. They travel at the speed of light :186,000 miles per second (300,000 kilometres). 802.11Continue reading “Wireless Signals”

TCP/IP vs OSI model

TCP/IP being the first of the models, is the foundation model from which Internet is based on. Into days world it is extremely unlikely to find a network that is not running TCP/IP. TCP/IP  consisting of the 4 layers, Network, Internet, Transport and Applications.  Network interface (layer 1):  physical components of network connectivity between theContinue reading “TCP/IP vs OSI model”

The Pro’s and Cons of utilizing IPv6 in today’s network Architecture design.

In todays world the need for devices connectivity  continues  to grow rapidly, As I look around my house, I count over 25 devices that require an IP Address and internet connection, Long gone are the days of just having the one desktop computer in the household. The need for more IP Address was the driving Continue reading “The Pro’s and Cons of utilizing IPv6 in today’s network Architecture design.”
