It is the most often cited of the COST 231 models (EU funded research project ca. April 1986 – April 1996), [1] also called the Hata Model PCS Extension. 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.
CPP is the cost of an advertising campaign, relative to the rating points delivered. In a manner similar to CPM, cost per point measures the cost per rating point for an advertising campaign by dividing the cost of the advertising by the rating points delivered. [4] The American Marketing Association defines cost-per-rating-point (CPR or CPRP) as:
The Hata model is a radio propagation model for predicting the path loss of cellular transmissions in exterior environments, valid for microwave frequencies from 150 to 1500 MHz. It is an empirical formulation based on the data from the Okumura model , and is thus also commonly referred to as the Okumura–Hata model . [ 1 ]
For example, a "2 by 4" wood stud wall with drywall on both sides results in about 6 dB loss per wall at 2.4 GHz. [2] Older buildings may have even greater internal losses than new buildings due to materials and line of sight issues. Experience has shown that line-of-sight propagation holds only for about the first 3 meters.
Gross rating points are a measure of the impact by a campaign using a specific medium or schedule. It quantifies impressions as a percentage of the target population, multiplied by frequency . This percentage may be greater, or in fact much greater, than 100.
One of the most difficult aspects of the real estate market is estimating the value of a home. With local market conditions changing all the time, it can be hard to accurately price a property. In ...
where L50 is the 50th percentile (i.e., median) value of propagation path loss, LF is the free space propagation loss, A mu is the median attenuation relative to free space, G(hte) is the base station antenna height gain factor, G(hre) is the mobile antenna height gain factor, and G AREA is the gain due to the type of environment. Note that the ...
The average cost of home insurance in the U.S. is $1,687 per year for a policy with $250,000 in dwelling coverage. However, home insurance premiums are unique to each individual.
