While plenty of people are ditching their landlines in favor of cellphones, most houses still have one. There are several good reasons to keep a landline, as we explain in this must-read Tip, which means most houses also have a standalone phone.
In many cases, that phone has a cordless handset, and why wouldn't it? Cordless is just more convenient than a phone with a cord that traps you in one spot. Unfortunately, a cordless handset uses radio waves, often the same 2.4Ghz microwaves as Wi-Fi, to connect to its base station.
