According to Anatel, in December 2003, 20% of the websites of ERBs were shared by others and 15% were share from others.

 

Electromagnetic Radiation

 

The cellular antenna radiation levels in ERBs are defined in the Regulation about limitation of the electric fields exposition, magnetic and electromagnetic in the radiofrequency band between 9 KHz and 300 GHz. Annex to the resolution n. 303 from july 2nd of 2002. Click here and check the Regulation ( in portuguese)

 

How far should we stay from cellular antennas?

 

Minimum distance of the antennas to be lesser exposed:

minimum distance (m) = 8.16 sqrt (e.r.p/f)

which f is the frequency, in MHz and

e.r.p. is the radiated effective power in the direction of bigger antenna gain, in watt.

Usual Values of Minimum distance

 

Using a usual band value found in cellular systems to the interested frequencies , we have:

 

	e.r.p
	1,000 W	100 W	10 W	1 W
f = 800 MHz	9.1 m	2.9 m	0.9 m	0.3 m
f = 1800 MHZ	6.1 m	1.9 m	0.6 m	0.2 m
