This signal is strong enough to cause muscle pain and brain damage.Devices with signals operating at 900 MHz can produce significantly stronger signals with longer range than the other commonly used signal at 2.4 GHz. Signals at 900 MHz have at least two times the range of 2.4 GHz signals.
- Fewer countries permit commercial devices operating at 900 MHz.
- Devices operating at 900 MHz are certified for use in North America.
- Europe requires the use of 2.4 GHz.

"Even when the microwave oven is working correctly, the microwave levels within the kitchen are likely to be significantly higher than those from any nearby cellular phone base-stations. Remember also that microwaves will travel through walls if the microwave oven is against an inside wall."
