Requirement about the frequency specs.
There is the difference of cordless phones type between handset and base unit such as the monitor, microwaves and other equipment or you can choose from difference of frequency.
900MHz: These $20 to $50 phones cover between 500 and 1,300 square feet--fine for a studio or a small home.
2.4GHz: You'll get a range of 2,200 square feet, so this is a better option for two-bedroom or larger houses and for talking from a deck or a backyard. But since these phones operate in the same frequency as Wi-Fi networks, the two tend to conflict. Prices start at $50 for a basic model and rise to $300 for a high-end expandable system.
5.8GHz: While the jury is still out on whether these phones perform well enough to justify their higher price tags, consider one if your nest is wireless. Compared with what you get from the 2.4GHz alternatives, call quality is generally better, but range is similar. You'll pay anywhere from $100 to as much as $400.
The different between analog and digital.
The three transmission types are analog, digital, and digital-spread spectrum (DSS), also known as spread-spectrum technology (SST). We recommend you stay far away from 900MHz phones because many still use analog signals, which are prone to excessive static; you'll find yourself changing channels frequently without hearing any appreciable difference. Digital models, on the other hand, encode your conversations into digital packets, dramatically improving call quality. Furthermore, DSS and SST phones transmit and receive a signal over multiple frequencies, so chances are you'll get a better-sounding and more-secure chat.
Do I need more than one handset?
Do you sprint to the phone and answer breathlessly on the last ring? Do you miss calls because you can't find the blasted handset, which you realize later is wedged between the couch cushions? Does your significant other hog the line? If any of those scenarios sounds familiar, you're an excellent candidate for an expandable cordless system.
Several 2.4GHz and 5.8GHz options currently on the market let you add more handsets to the base. Some limit you to just one extra, while others can support up to 10 on a single jack. Along with the usual chatting functions, you'll get paging and teleconferencing, too.
What's the deal with changing channels?
If you're hearing a lot of static while talking to Grandma, try another channel. The more channels your phone has, the better. Look for autochannel search, a function that automatically finds the next free channel when static threatens a call in progress. Basic 900MHz phones have 20 to 60 channels, while 2.4GHz models offer 50 to 100.
