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.
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 ]
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:
For very low-power systems, such as mobile phones, signal strength is usually expressed in dB-microvolts per metre (dBμV/m) or in decibels above a reference level of one milliwatt . In broadcasting terminology, 1 mV/m is 1000 μV/m or 60 dBμ (often written dBu). Examples. 100 dBμ or 100 mV/m: blanketing interference may occur on some receivers

The Lee model for point-to-point mode is a radio propagation model that operates around 900 MHz. Built as two different modes, this model includes an adjustment factor that can be adjusted to make the model more flexible to different regions of propagation.
F1 Racing Simulation is a racing simulation game, developed for Microsoft Windows by Ubi Soft in 1997. [2] The game is based on the 1996 Formula One World Championship, and is the first of the Racing Simulation games made by Ubisoft, being the predecessor to Racing Simulation 2, which was released in 1998.
F1 2009, the first video game by Codemasters, was announced in May 2008 after Codemasters secured the official Formula One video game licence. The game was developed by Sumo Digital and based on the 2009 Formula One World Championship season. [79] It was released on 16 November 2009 for Wii and PlayStation Portable platforms. [80]
