The 800 MHz frequency band is a portion of the electromagnetic spectrum, or frequency band, that encompasses 790–862 MHz.. Being a part of the spectrum known as "UHF Bands IV and V" (i.e. 470 MHz to 862 MHz) it was allocated by the ITU to Broadcasting as the primary user in Region 1 and was used for analogue television broadcasting before changing to digital terrestrial television in many ...
Frequencies above 30 MHz are referred to as Very High Frequency (VHF) region and those above 300 MHz are called Ultra High Frequency (UHF). The allocated bands for amateurs are many megahertz wide, allowing for high-fidelity audio transmission modes ( FM ) and very fast data transmission modes that are unfeasible for the kilohertz -wide ...
This is the navigation box for the International Amateur Radio Bands.. All bands in this template are either mentioned in the International Telecommunication Union's "Table of Frequency Allocations" or the table's footnotes, with the exception of allocations listed in italics.
This model is the combination of empirical and deterministic models for estimating path loss in an urban area over frequency range of 800 MHz to 2000 MHz. [ 2 ] COST (COopération européenne dans le domaine de la recherche Scientifique et Technique) is a European Union Forum for cooperative scientific research which has developed this model ...
Further GSM-850 is also sometimes called GSM-800 because this frequency range was known as the "800 MHz band" (for simplification) when it was first allocated for AMPS in the United States in 1983. In North America GSM-1900 is also referred to as Personal Communications Service (PCS) like any other cellular system operating on the "1900 MHz band".
The Michigan State Police already operate on the 800 MHz band and the Hillsdale County Sheriff’s Office received funding from the state to make the transition already.
Hillsdale County voters will be asked Aug. 6 to reconsider a ballot measure aimed at funding upgrades to the county's emergency radio technology.
It addressed a proposal to open the 800 MHz band. This program defined technical details such as "channel access time," "system growth capability," and "reliability." [ 2 ] Project 16A identified the organizational advantages that would accrue from assigning individual unit addresses and adding another "group" address element.
