> The commercial sale real-time service system
(POS) realizes the commercial automation important foundation.

communication lines question, this causes the bank card the use to
concentrate in some large-scale markets and the upscale expense place,
thus has lost the massive opportunities which expends with the bank
card. The Shenzhen China territory science and technology
limited company in view of the present line-wire communication POS
system existence question and the insufficiency, based on independent
research and development GPRS/CDMA the 1X router product, promoted
wireless network has realized the solution with the aid of GPRS/CDMA
the 1X which POS machine turned on. GPRS/CDMA the 1X wireless data transmission has the
equipment cost lowly, the data transmission safe is reliable,
characteristic and so on use nimble convenience, extremely suits POS
machine on the application. The migration data communication
uses IP Over high speed the PPP realization data terminal,
long-distance turns on, may provide the macrozonality the wireless IP
connection, is suitable to the profession and the enterprise level
user development wireless data application, for is dispersible
long-distance 接入�wireless provides the high performance to turn
on. • Nimbly disposes the POS equipment, the
expansion brushes the card range of service. GPRS/CDMA 1X
wireless turns on the biggest superiority is enable the existing POS
system to get rid of the wire communications network the restriction,
uses wireless turns on POS machine the place which may use in the
handset all to be possible to apply, but conveniently disposition Yu
Gezhong situation. • The system transmission capacity answers the
purpose. GPRS/CDMA the 1X technology specially suits to POS
system this kind needs to transmit the massive burst characteristics
data situation. • Has the competitive ability the performance
price compared to, as a result of GPRS/CDMA the 1X service 按数
according to the current capacity charge, based on GPRS/CDMA 1X POS
scheme according to transmission expense extremely inexpensive, the
operation expense comparatively line-wire communication POS system is
inexpensive. • Enhances 接é€çŽ? reduces the transaction
time. After the POS machine terminal turns on GPRS/CDMA the 1X
network, is in one kind as necessary in the striation condition,
