The big question at the moment concerns the impact that the arrival of 5G will have on the general public. Through the French federal office of communication (ANFR), I have in my possession a document which can be considered “a scoop”. Here below the summary and the conclusions:
Installation of a Mobile Phone Mast
Here below is the installation file concerning a relay antenna belonging to the provider Orange, situated Boulevard de Dunkerque in Marseille on the roof of a local housing apartment block.
This antenna site has the particularity of having a 5G mast installed (not yet transmitting) as well as already possessing antennas for the 2G, 3G and 4G systems (which are functioning). The frequency band reserved for the provider Orange is between 3700 and 3800 MHz.
General description for a relay antenna support
Relay antenna installation files always contain the PIRE emission strengths for transmission set in dbW for each of the 2G, 3G, 4G and 5G frequency bands. These emissions in dbW can easily be converted into Watts
What does PIRE stand for?
PIRE means: “Maximum Equivalent Isotropically Radiated Power”. This power expressed in dbW or Watts corresponds to the actual power radiated on exiting the antenna:
Power PIRE (in Watts or dbW) = the electrical power of the transmitter (in Watts) isotropic gain of the antenna.
Details of the maximum emission power set for 5G
Calculation of the emission power concerning 2G
|
GSM 900 (2G) |
25,1 dbW |
= 323 Watts |
|
Total 2G |
25.1 dbW |
= 323 Watts |
Calculation of the emission power concerning 3G
|
UMTS 900 (3G) |
28,1 dbW |
= 645 Watts |
|
UMTS 2100 (3G) |
32,8 dbW |
= 1900 Watts |
|
Total 3G |
Les dbW ne s’additionnent pas |
= 2545 Watts |
Calculation of the emission power concerning 4G
| LTE 700 (4G) |
32 dbW |
= 1584 Watts |
|
LTE 800 (4G) |
31.8 dbW |
= 1500 Watts |
|
LTE 1800 (4G) |
33,4 dbW |
= 2187 Watts |
|
LTE 2100 (4G) |
36,1 dbW |
= 4000 Watts |
|
LTE 2600 (4G) |
35,9 dbW |
= 3890 Watts |
| Total 4G |
The dbW are not added together |
= 13161 Watts |
Details of the maximum emission power set for 2G, 3G, 4G
Calculation of the total emission power of 2G, 3G and 4G together
323 + 2545 + 13661 = 16029 Watts
Calculation of the emission power concerning 5G
|
5G / NR |
45 dbW |
= 31600 Watts |
|
Total 5G |
45 dbW |
= 31600 Watts |
Calculation of the total emission power of 2G, 3G, 4G and 5G together:
47629 Watts
Conclusions
> The electromagnetic radiation emitted by a 5G mobile phone antenna alone in the 3400 to 3800 Mhz band will be twice as strong as the total amount of radiation from mobile masts for 2G, 3G and 4G technologies when added together
> Moreover, the installation of other 5G frequency bands is envisaged: 1427 Mhz to 1517 Mhz : 24.25 to 27.5 Ghz as well.
> Local residents in areas where these relay antennas are installed will, in the near future, be exposed to levels of emission density of W/m2 which is at a minimum 3 times higher than today.
