UPDATED with a comment from Gregor Duerrenberger suggesting that Mike and myself made technical mistake…So how it is – when cell tower emits 10 times less radiation power – will cell phone increase its power to compensate and keep connection or not? Discussion is open below…
Quoting Gregor Duerrenberger:
just scanned over your Repacholi blog and saw that you, as Mike, stick to an argument that is technically not valid: The output power of a handset ist regulated by the base-station, that’s true, but it is not the strenght of the base-station signal received by the mobile phone that sets the handheld output power. It is the signal strenght of the handelheld received by the base-station antenna. So, if you reduce output power of the base-station and the location of the handheld remains the same, the handset does not increase its power (due to the lower base station signal level) because the environmental radio communication conditions for the mobile phone did not change.
The best, Gregor

However, health hazard issue, as presented by Mike Repacholi, is not invalidated by this new development…
In December 2013, former Head of the WHO EMF Project visited India and gave lecture as well as news media interviews. At the issue was the decision of India to implement new radiation emission safety limits for cell towers that are 10 times lower than the WHO-recommended ICNIRP levels.
Indian newspaper ‘Business Standard’ published on December 14, 2013 an article, interviewing Mike Repacholi, under the headline “India’s mobile tower radiation norms absurd, says WHO” and continued with a subtitle “WHO expert says rules increased emission hazard for phone users; tells govt to review norms”.
In this ‘Business Standard’ article Mike Repacholi is quoted as saying:
“India’s decision to reduce the power of the base stations will not minimise any risk. If you reduce the power of a base station, your mobile handset transmits more frequency to stay connected to the network. As the handset is closer to the body, it could cause some health hazard.”
Later, the journalist, Sounak Mitra, stated that “Repacholi had told the government hand-held mobile devices might cause health hazards, but not the base stations of mobile towers.”
The both above quotes clearly indicate that Mike Repacholi considers that hand-held cell phones may cause health hazard to its users.
As the reason for the increased health hazard Mike Repacholi said “…If you reduce the power of a base station, your mobile handset transmits more frequency to stay connected to the network…”. Indeed, cell phones work this way.
However, as we all know, and are assured by cell phone manufacturers, cell phone never emits more radiation than the safety standards permit, even if cell tower has low emission or is far away. Such increased emissions, by cell phones, should not cause any health hazard as we are continuously assured by the WHO.
“…A large number of studies have been performed over the last two decades to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use…”.
So, what is the real position of the WHO?
Are higher emissions from cell phones, caused by lower emissions from cell towers, hazardous to people? From the article in India’s ‘Business Standard’ it seems that WHO’s expert Mike Repacholi thinks so.
It is not only India’s problem what the hazard is. It is a global problem.
Cell towers, especially in the countryside are located far from each other. It is often so that the signal received by cell phone is low. The same might happen also in cities – I have such problem at my home.
Quotes presented above indicate that Mike Repacholi considers that globally all cell phone users, having poor signal from the cell tower, are at risk of health hazard. At least this is the logical conclusion when reading the article in the India’s ‘Business Standard’.
