Cordless Phone

Cordless Phone Basics

Cordless phones transmit signals at different frequencies using analog or digital technology. Costs are directly related to the number of features, but you always get what you pay for and wish you had when you don’t.

• 900-Mhz phones are now the bottom of the technology barrel, fairly inexpensive but increasingly difficult to find. Avoid.

• 2.4-GHz. Most phones use this frequency. Many wireless products, including computer networks, home security monitors and speakers are jammed into the same band. Analog phone models are susceptible to RF interference from these, and may cause interference in other products. But DSS phones labeled "802.11-friendly" are least likely to interfere with wireless computer networks.

• 5.8-GHz. The new frequency band on the block, rapidly replacing all older models. Their main advantage is less susceptibility to RF interference because there are fewer products currently using the 5.8 GHz band.

Analog Cordless Phones $15-$100

This older technology is the least expensive since it’s on the way out, mainly because the phone transmissions aren’t secure. Anyone with an inexpensive RF scanner can eavesdrop on your conversation. They’re more prone to static and RF interference from wireless products.

Digital Cordless $50-$200

Digital offers superior security and are less susceptible to RF interference or create interference in other wireless products. Models include one base with two or more handsets, with the additional handset having its own charging cradle. Recommended.

Digital Spread Spectrum $200-$300

These phones distribute a call across several frequencies, providing added security and additional shielding from RF interference. The lower frequency 2.4-GHz DSS phones or some models with handset-to-handset talk capability may interfere with baby monitors and other wireless products operating on the same frequency. Recommended.

Hardware Options

Basic units are stand-alones, with built-in answering machines, supporting multiple handsets from one base which allows installations in rooms lacking phone jacks. While 2.4-GHz phones offer the widest model and price ranges, they provide the least security and interference from other wireless tech products. Privacy is always an issue, so go with 5.8-GHz DSS or digital, because the last thing you want to worry about how much of your conversation is being overheard, especially when discussing proprietary subjects.

Packaging Can Be Deceiving

Closely check packaging copy and look for "digital phone," "digital spread spectrum (DSS)" or "frequency-hopping spread spectrum (FHSS)." Meaningless copy gems include "phone with digital security code," "all-digital answerer," or "spread spectrum technology." None of these indicate that the phone is as secure as it should be.

Check the fine print for the frequency each model offers. Most packaging displays “2.4-Ghz” or “5.8-Ghz” labels, but most of these are not digital but analog phones. Look for Caller ID capability and a headset jack.

Take A Test Drive

Determine comfort levels by trying different models in the stores. Handset fit is one factor. Make sure the handset fit’s the contours of your face and has a rounded edge earpiece and recessed center that rests over the middle of your ear. Test buttons and controls for ease of use. Make sure you can manipulate them without hitting two keys at once. Make sure you can read the numbers.

Cordless Answering Machine Functions

Digital answering machines models offer stand-alone and combo units. While combos take up less desktop space, important if your desk is already groaning under the weight of your PC, the entire device has to be replaced if it goes bad. Answering machine standard features include ring number selection before answering, toll-saver, call screening, remote message retrieval, day/time stamp, selective message deletes, adjustable speaker volume and ability to retain messages in case of short-term power outages.

Small business owners will find these features useful: number of mailboxes, advanced playback controls, remote handset access, conversation recording, message counter display, visual indicator new message alert and ability to record customizable messages

Warranty

Phones are prone to power spikes and outages and the chips easily fried. Always make sure that you use a surge protector for protection, but go with the warranty, especially on the more expensive units.
