Need a new home phone.What the heck is the difference between these?
The primary difference is in how far you can range from the "docking station" (the higher the GHz, the farther the range); resistance to interference (the higher the GHz, the better, but see the next paragraph), and, sometimes, the number of different channels which can be used for a conversation to prevent contention with other people near you using the same phone or using a phone scanner.
One caveat: if you have a wireless router in your house to share an Internet connection, stream music, etc., it transmits at 2.4 GHz. A 2.4GHz phone may cause problems. Go for either a 900 MHz or a 5.8 GHz phone to avoid interrupting your wireless.
Thanks Steve, the 900MHz is what I have,so will stick to it.
