Well ... 900 MHz. GSM. CDMA. - Sounds like outdated to me. What about what we are using daily e.g. 2.6 GHz LTE and 3G signals.

- agumonkey 10y agoWhat about wifi ? Since I, we, are sitting next to routers all day long, which I guess are sending more EMW energy through us than 3G towers.
- maxerickson 10y agoThe exposure from towers and base stations will be tiny compared to the exposure from devices. Inverse square law and all that.
- agumonkey 10y agoThat was my assumption too but I never tested it.
- Gnarl 10y agoWith regard to cell-towers: the inverse-square law will underestimate your radiation exposure from a cell-tower, because they are directional and the inv.sq.law relates only to to perfectly isotropic radiators. In other words: you need to factor the cell-tower antenna gain (typically between 7-10dB) into your calculation.
- Sephr 10y ago700-900 MHz is used for LTE as well, and is usually preferred due to its building penetration characteristics.
