Wireless Point-to-Multipoint Links (PMP) & WiMax - The simplest way to explain how a PMP works is by describing the cellular data service offered by cellular carriers. One or more subscribers (mobile PC and smartphone users) in a given geographical area connect to a cellular base station equipped for data services. The base station controls the transmissions. The "point" in a PMP network is a base station and the "multipoint" are the subscribers which may be stationary (links to homes or businesses) or mobile (Internet access enabled notebook PC or handheld devices, police cars, fire trucks). The base "point" controls acccess.
Examples of applications of PMP technology:
Prime Performance Technologies, Inc. (PPT) designs and installs and maintains wireless PTP links. Newer radio products offer high security (FIPS140-2, FIPS197) and one or more ports on the outdoor radio for a direct connection to cameras. The radios are very cost effective with a very short ROI.
Most PMP radios operate in the in the unlicensed band (900 MHz, 2.4 GHz and 5 GHz) and in the licensed 4.9 GHz band which is reserved for public safety applications.
WiMax, a 4G wireless service pioneered by Clearwire, is a PMP network that operates in the licensed 2.3, 2.5 and 3.5 and 3.65 GHz bands. WiMax services can be offered by public utilities (carriers) and can be deployed by other organizations such as developments (housing and business), towns, counties, industrial parks, corporate campuses and colleges.
PPT has partnered with a large number of world-class manufacturers of wireless PMP equipment including Airaya, AvaLAN, Microhard, Motorola, Proxim, PureWave and Redline and is able to design and support PMP links that meet a diverse set of requirements.
