Motorola PF B65 telephones feature global system for mobile communications
(GSM) air interface, general packet radio service (GPRS) transport technology, and
wireless application protocol (WAP) Internet. The PF B65 incorporates a color user
interface (UI) that is both icon and list-based for easy operation, allows Short
Message Service (SMS) text messaging, and includes personal information manager
(PIM) functionality. The PF B65 is a dual-band phone that allows roaming within
the GSM 900 MHz and digital cellular system (DCS)1800 MHz bands.
PF B65 telephones support GPRS and SMS in addition to traditional circuit
switched transport technologies. GPRS, where available, provides substantial
increases in mobile data communications performance and the efficient use of radio
spectrum. Data transmission rates for GSM networks can potentially increase from
the current rate of 9.6 kbps up to a theoretical maximum of 171.2 kbps. An increased
data rate is by no means the only benefit provided by GPRS. A key advantage is
the provision of a permanent virtual connection to the network. This "always on"
connection is possible because GPRS uses packet data transfer so that, for example,
email can be downloaded in "background mode." There is no need for the user to
reconnect before requesting a service, eliminating connection set-up delays and
adding convenience and immediacy to data services access. The "virtual" nature of
this connection means that network resources are not consumed during periods
when a user is not actually sending or receiving data.
The telephones are made of polycarbonate plastic with a metal enclosure. The
display and speaker, as well as the keypad, transceiver printed-circuit board (PCB),
microphone, charger and headphone connectors, and power button are contained
within the clam form-factor housing. The standard 550 mAh Lithium Ion (Li Ion)
battery fits behind the back cover.
The phone accepts 3V mini subscriber identity module (SIM) cards which fit into
the SIM holder underneath the battery. The antenna is a fixed stub type antenna.
Inexpensive direct connection to a computer or handheld device via RS232 or USB
for data and fax calls, and for synchronizing phonebook entries with TrueSync®
software, can be accomplished by using the optional data cable and soft modem.
PF B65 telephones use advanced, self-contained, sealed, custom integrated circuits
to perform the complex functions required for GSM GPRS communication. Aside
from the space and weight advantage, microcircuits enhance reliability, simplify
maintenance, and provide a wide variety of operational functions.
Features available in this family of telephones include:
• Low voltage technology that provides increased standby and talk times
• Extended GSM (EGSM) channels
• Tri-coder/decoder (CODEC) that allows full rate, half rate, and enhanced full
rate modes of transmission
• Supports mobile originated/mobile terminated SMS, concatenated SMS, and
cell broadcast messages
• Supports GPRS, circuit switched, and SMS networks
