What the exact
range of a cordless phone is not something that is easily stated.
Range is highly dependent upon the environment the phone is used
in. You will get better range in a less electronically noisy environment.
Pagers, computers, cell phones, TVs, microwaves, etc. can effect
your range. Range can also be affected by the location of the phone's
base station and antenna, and physical barriers such as walls. Even
weather can affect range.It
may be best to think of cordless phones in terms of their relative
range. 900 MHz phones will provide better range than the older 46/49
MHz analog phones.
900 MHz
spread spectrum phones offer even greater range. And the newer 2.4
GHz phones will provide you with the best range. 46/49 MHz cordless:
46/49 MHz phones have been standard on the market for many years.
These are good phones for home use or a small, quiet office but
tend to have more interference. 900 MHz analog cordless:
If you’d like to take advantage of the 900 MHz frequency, but you’d
also like to save a little money, think about an analog 900 MHz
cordless. It doesn’t have the digital signal enhancements, but in
a small office, it should give you very good cordless reception.
You will see better performance than a conventional 46/49 MHz analog
cordless. 900 MHz digital cordless:
If you don’t really need a top-of-the-line spread spectrum phone,
but still want the benefits of 900 MHz, consider a digital 900 MHz
cordless phone. Originally reserved for the military, the 900 MHz
frequency has become available for civilian use. This higher frequency
coupled with digital technology results in a stronger, clearer signal
than 46/49 MHz analog cordless phones offer, and a range that is
2 to 3 times farther in many cases. 900 MHz spread spectrum phone:
Spread spectrum gives you superior clarity and range in a cordless
phone. They "spread" signals over several frequencies to scan for
the clearest channels rather than locking onto one channel. If you
have a very large office, or if you’d like to take advantage of
unprecedented digital clarity, choose a spread spectrum phone.
2.4 Ghz This new technology separates your signal into two different
frequencies making it virtually interference free. It also incorporates
the channel-scanning of spread spectrum to give you the best reception
available in a cordless phone. If you need long range and excellent
clarity this is generally the best choice.
What
Is, TAD, ITAD, CID, CIDCW ?
These are terms used for features on a telephone. TAD
or ITAD stand for Telephone Answering Device or Intergrated Telephone
Answering Device. A Telephone Answering Device is what you normally
call an answering machine and since it is intergrated that means it
is built into the phone. CID stands for Caller ID. This is a feature
to retrieve the name and number of the person who is calling you.
Most phone companies require that you subscribe to the Caller ID service
for this feature to work. CIDCW is the same as Caller ID except that
when you subscribe to the Call Waiting and Caller ID services from
your phone company, you will be able to see who is calling when you
are currently using the phone line.
