The transfer rate, or "data rate" refers to the speed with which data is transferred from its source to its destination, such as from one computer to another over a network, or from the computer to the disk drive. It's measured like we would measure any rate of speed-in units of information per the unit of time, like miles per hour. On a computer you may hear transfer rates expressed in terms like bits per second, megabytes per second, or characters per second.

Internet access has become a standard feature on most of our mobile devices. But there’s more than one way to connect to the Web with those devices these days. In this article, we’ll help you determine what you need in order to get started with each of these technologies and explain a bit about why you would want to choose one over the other or perhaps go with both.

The MAC layer is the "Brain" of WiFi. The first version of 802.11 (the 802.11 legacy published in 1997), defined the MAC layer by incorporating a number of features crucial, such as sharing of speech among users, the terms of network connection, error control or security.

WiMAX (Worldwide Interoperability for Microwave Access) is the result of an initiative launched in 2001 by the WiMAX Alliance. Its aim was to promote the IEEE 802.16 standard by proposing to verify compliance and equipment interoperability. As we shall see, many options have been proposed to achieve communication.

The IEEE 802.15 group was set up in March 1999 to reflect on wireless networks with a range of ten meters, or WPAN (Wireless Personal Area Network), with the aim of making connections between different portable one user or multiple users. This type of network can connect a laptop, cell phone, PDA or any other device of this type. Three service groups were defined, A, B and C.

Before transmitting information on a transmission medium, it must be encoded of adequately. Networks must allow very high speeds over distances more or shorter. In this context, three approaches are possible for coding bits from applications:

Another solution to obtain a broadband distribution network is to use the wiring of cable operators, when it exists. This wiring has long been made of CATV (cable TV), whose bandwidth exceeds 800MHz easily. Today, this infrastructure is slightly modified by the introduction of systems HFC (Hybrid Fiber/Coax), combining a fiber portion between the head end and the beginning of the service by the CATV. This topology is illustrated in Figure.

ISO (International Standardization Organization) standard has its own architecture as the OSI (Open Systems Interconnection). The architecture ISO is the first to be defined, and so relatively parallel to the Internet. The distinction between the two is that the ISO formally defines the different layers architecture, while the Internet architecture is applied to achieve a practical environment.
