A description of the wireless technology applied to computer processing

wireless mobile communication

Only recently has the industry been taking steps to formulate a standard that is more suitable to data transmission. WiMax will provide high-speed wireless Internet over very long distances and will most likely provide access to large areas such as cities.

For the Personal Computer.

Wireless definition computer

Another method is a terrestrial method, in which two microwave towers with a clear line of sight between them are used ensuring no obstacles to disrupt that line of sight. Frequency hopping is an additional measure that also enables data security. The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter. With advent of PCMCIA cards, notebook computers are being substituted for regular desktop machines with complete connectivity of the desktop machine. For a while, its cost made it popular, but now it's becoming less common as faster standards become less expensive. Modems[ edit ] Modems MOdulator-DEModulator are used to connect network nodes via wire not originally designed for digital network traffic, or for wireless. This chip will be used in many communication products, especially wireless. In early tests at Apple, the hop system showed microsecond hop times, microsecond clock recovery, and a 5-microsecond lapse between the time an empty channel is sensed and transmission begins. On the physical layer issue, the

In-vehicle computing and fleet computing[ edit ] Many commercial and government field forces deploy a rugged portable computer with their fleet of vehicles. A network interface controller NIC is computer hardware that provides a computer with the ability to access the transmission media, and has the ability to process low-level network information.

The information cannot be travelled through obstacles in an infrared system, but can be inhibited by light. Although newer, faster standards like With advent of PCMCIA cards, notebook computers are being substituted for regular desktop machines with complete connectivity of the desktop machine.

Types of wireless network

This greatly reduces interference. The pairing process identifies and connects any two devices to each other. It can be thought of as a multi-port bridge. There are also attacks that exploit software vulnerabilities from both the web browser and operating system. If any machine detects a collision, it will send out a jamming signal to all the others. They were originally designed to transport circuit mode communications from a variety of different sources, primarily to support real-time, uncompressed, circuit-switched voice encoded in PCM Pulse-Code Modulation format. Smartphones are the same devices as tablets, however the only difference with smartphones is that they are much smaller and pocketable. The routing information is often processed in conjunction with the routing table or forwarding table.
