Просмотр инструкции сотового cdma LG C TM-510, страница 6
The LG-TM510 phone has been designed to
operate on the latest digital mobile communication
technology, Code Division Multiple Access (CDMA).
This CDMA digital technology has greatly enhanced
voice clarity and can provide a variety of advanced
features. Currently, CDMA mobile communication
technology has been commercially used in Cellular
and Personal Communication Service (PCS).
The difference between them is the operating
frequency spectrum. Cellular uses 800Mhz and PCS
uses 1.9Ghz. The LG-TM510 can operate on both
frequency, we usually call it dual-band phone. Also,
LG-TM510 works on Advanced Mobile Phone
Service (AMPS). We call it triple-mode phone. If one
of the Cellular, PCS and AMPS base stations is
located nearby, Call fail rate of triple-mode phone is
less than dual-mode phone or single-mode phone.
The CDMA technology adopts DSSS (Direct
Sequence Spread Spectrum). This feature of DSSS
enables the phone to keep communication from
being crossed and to use one frequency channel by
multiple users in the same specific area, resulting
that it increases the capacity 10 times more
compared with that in the analog mode currently
used. Soft/Softer Handoff, Hard Handoff, and
Dynamic RF power Control technologies are
combined into this phone to reduce the call being
interrupted in a middle of talking over the phone.
SUBJECT
* In the United States and Cananda, the SAR limit for
mobile phones used by the public is 1.6 watts/kg (W/kg)
averaged over one gram of tissue. The standard
incorporates a substantial margin of safety to give
additional protection for the public and to account for any
variations in measurements.
