Going Wireless at Home
The Nokia 9290 combines phone, fax, e-mail, calendar and imaging in a handheld unit.
A few years ago, most wireless services operated on a standard analog network. Since then, a new, higher-frequency digital layer has been added to the airwaves. As a result, there now are three types of phones commonly in use - older analog-only phones, digital-only phones and dual-mode phones that can switch between analog and digital. Having the ability to switch between analog and digital is important mainly for those who use their phone on the road, since home service requires one or the other. Until digital inevitably replaces analog technology it will continue to be used widely across the country. However, analog has drawbacks that cripple its day-to-day use in the home. It is, for instance, less secure, since an analog transmission can be intercepted easily, relative to a digital transmission that is broken into data and unscrambled at the receiver. The service plan you choose often will dictate the kind of phone you buy.
However, here are some general suggestions for selecting equipment that will work well in a home environment: Stick to the name brands Companies like Nokia, Qualcomm, Motorola, Ericsson and Samsung, to name a few, offer many models that are powerful and inexpensive. All of these manufacturers offer a wide array of up-to-date technologies, great performance and are supported by many service providers. Since most accessories and add-ons are developed initially for standardized, name-brand phones, owning one can help the consumer keep his or her options open for these emerging technologies.
Digital is better
In addition to their security advantages, digital phones generally have better power management capabilities. Most run on either lithium ion (Li-Ion) or nickel metal hydrate (NiMH) batteries, a big improvement over their older counterparts' nickel cadmium (NiCAD) batteries. The newer batteries resist the memory effect, in which batteries not fully drained would fail to recharge fully. Better batteries mean extended standby time, faster charges and longer battery life. That can be crucial in a home-use situation when the phone is always on.
