The newer devices use the 900 MHz (33 cm) band, which has much higher range and much lower bandwidth than Bluetooth which uses the 2.4 GHz band, or WiFi which uses the 2.4 and 5.0 GHz bands. For the same power output, 900 MHz generally has more than twice the range of 2.4 GHz, and at least 4 times that of 5.0 GHz. 900 MHz can also penetrate foliage and buildings better than higher frequencies and it's less susceptible to multi-path propagation. The main downsides to 900 MHz are available bandwidth, 26 MHz compared to 83 MHz for 2.4 GHz and 228 MHz for 5.0 GHz, and much slower data rates, as low as 9% of 2.4 GHz and 4% of 5.0 GHz speeds. 900 MHz used to be very common for cordless phones 25-30 years ago, but most manufacturers have switched to other bands. Well, how far can that reach? Our current Wi-Fi cant even reach from our house to the edge of our property where mom and I were cutting firewood. I think she said it was 5 to 10 acres to that fence or something. --- Official Fierce Deity in my own mind.
