Does The More Ghz Your Cordless Phone Have Mean The Longer Range You Get?
I need a cordless home phone with longer range the on I have now is 5.8GHz but it doest reach as far as I need it to. Does the higher the GHz mean I can get longer range? If not than can someone reccomend me a phone that gets good range?

no, the frequency – measured in GHz, does not determine the distance. It does determine who shares the phone operational band/frequency. Fewer users, the better. Right now, 5.8GHz (5800MHz) has the fewest users and clearer channels. This will change…
No, it’s the opposite. The lower the GHz the longer the range, but there are other issues. I would be wary og buying 900 MHz or 2.4 GHz phones because these are crowded frequencies (WiFi, microwaves, baby monitors …) DECT phones use the 1.9GHz frequency that is exclusive to cordless phones. DECT phones have great range, free of interference and are typically cheap. Nearly all manufacturers make DECT phones and they are pretty much a commodity item. The Panasonic KX-TG1032S is one of many safe options available.
Ghz is is gega Hertz that is frequency and frequency is reciprocal of wavelength . Wavelength responsible for range so go for a low frequency phone
more GHz means better signal in quality as well as range.
