The Realm of Wireless Networks

This new blog is all about wireless networks. The term wireless network is widely used to describe a telecommunications network whose interconnections between nodes is implemented without the use of wires. These networks are commonly implemented with some type of remote information transmission system that uses electromagnetic waves.

It is be difficult to categorize and compare wireless data networks exist because they exist in huge numbers and varieties. For instance, there are mobile telephone networks that run over wireless voice networks and others that on their own physical layer networks. There are also less common types of wireless networks that are intended only to connect small devices over short distances.



Major Wireless Networks Types


Multichannel Multipoint Distribution Service
- is a broadband wireless point-to-multipoint specification utilizing UHF (Ultra High Frequency)
communications.

Cellular Digital Packet Data- is an overlay to the existing D-AMPS cellular network, which enables users to transmit packets of data over the cellular network using a portable computing device and a CDPD modem.

Packet Data Cellular- a wireless standard providing two-way, 19.2 kbps packet data transmission over existing cellular telephone channels.

General Packet Radio Service- a method of enhancing 2G phones to enable them to send and receive data more rapidly

High Speed Circuit Switched Data
- a circuit-switched wireless data transmission for mobile users at data rates up to 38.4 Kbps, four times faster than the standard data rates of the
Global System for Mobile

Local Multipoint Distribution Service- is a system for broadband microwave wireless transmission direct from a local antenna to homes and businesses within a line-of-sight radius

Wi-Fi -refers to any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc

1x Radio Transmission Technology- The first version of (CDMA2000) wireless cellphone technology that allow data to be transmitted at rates of 307 Kbps downstream and 153 Kbps upstream as well as twice the voice capacity on a single 1.25MHz Code Division Multiple Access CMDA) channel in new or existing spectrum.

Worldwide Interoperability for Microwave Access
- a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access
