Motorola PF 0B89 telephones are the smallest and lightest global system for mobile
communications (GSM) general packet radio service (GPRS) wireless application
protocol (WAP)-enabled mobile phones currently available. The PF 0B89
incorporates a new user interface (UI) for easier operation, allows short message
service (SMS) text messaging, and includes personal information manager (PIM)
functionality. It is a tri-band phone that allows roaming within the GSM 900 MHz,
digital cellular system (DCS) 1800 MHz, and personal communications services
(PCS) 1900 MHz bands.
PF 0B89 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 re-
connect 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.
PF 0B89 telephones have a clam form factor. They are made of a polycarbonate
plastic with the display and speaker located in the flip. The bottom part of the clam
(front housing) contains the keypad, transceiver printed circuit board (PCB),
microphone, flex connection, external accessory connector, smart button, volume
buttons, and voice button. The battery and battery door are integrated into a single
unit with two types available to provide standard and extended operation. The
phone accepts both 3V and 5V mini subscriber identity module (SIM) cards which
fit into the SIM holder underneath the bezel on the outside of the flip. The antenna
is a fixed stub type antenna. The service indicator (status light) displays flashing
green while in-service, flashing amber when roaming, flashing red while out of
service, and alternating red / green when ringing.
PF 0B89 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 basic reliability,
simplify maintenance, and provide a wide variety of operational functions.
Features available in this family of telephones include:
• Lower 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 SMS, concatenated SMS, and cell broadcast messages
• Supports GPRS, circuit switched, and SMS networks
• WAP 1.1 compliant
• 96 x 64 pixel liquid crystal display (LCD) with 3 lines of text, 1 line of icons,
and 1 line of prompts
• Display zoom
