It is clear that manufacturers are aware of the concern about SARs from users, however the most driving force is probably /design/. Many users are willing to pay extra to get rid of the antenna that get caught in clothes etc. Designers are glad to be free to model a phone without the constraints of an antenna on top. Also the emerging use of fractal antennas and compact helix antennas are contributing to the trend. Is is /not/ clear that these new antennas give less symptoms for the users. Many new antennas give off higher magnetic field than the old ones (in the near field E and H isn´t coupled to eachother). So, be aware and very critical about measurements or talk about electric field strength near the phones, it may well be that the E field is less but possibly the H field is higher than others... And to make it worse, we already have indications that SAR is not the best measure when compared to complaints from users. Also, SARs that are computed must be computed from both E and H near fields to be valid. I doubt that any of the major manufacturers are going to advertise "low emission", if they do they will implicitely say they have had "high emission" phones earlier! We may /hope/ the new phones are better, but will it be enough? As for actual measurements, the best thing is to nag, beg and lure the customer organisations to fund and publish measurements on all phones on the market. If the customers DEMAND to know SARs for products sold it may come to a point where the manufacturers has to publish the figures they keep as company secrets. Get the customer organisations going on this!
