There are variants for different environments (city, rural) and frequencies, but they all show the same pattern.

The Okumura-Hata formulas are internationally accepted and part of the mobile phone standards and acceptance rules. This is a formula due to the Japanese scientists Okumura and Hata, who have done endless series of measurements and have compiled Cellmax Ret Software Definition Series Of Measurements See the post from Mateusz Buczkowski in this blog for a general introduction of the concept of path loss. The power of electromagnetic radiation goes down with distance extremely fast when moving away from the transmitter. Id like to deal with the reality of mobile network radiation in this post. Public opinion is first and foremost against the cell phone towers as they are the visible landmarks of the technology.Įach time a tower for a cellular network is built or planned to be built in a city or near a rural settlement, there is a new discussion about health issues of mobile phone or network radiation. This time it is quite a bit heavier than in the past, mainly due to the existence of social networks, which tend to spread alleged bad news and alarming stories literally at light speed. This is nothing new: this phenomenon is with us since the 1990s those alarming claims have been made around the launch of UMTS (3G) in the year 2000, and with the start of LTE in 2010, too.

Since it doesnt make a lot of sense to radiate in all spherical directions (upwards, downwards) antennas are constructed to focus the radiation into a solid angle, typically 120 degrees wide and 15 to 20 degrees high.
