Motorola V70 mobile telephones feature global system for mobile communica-
tions (GSM) air interface, general packet radio service (GPRS) transport technology,
and wireless application protocol (WAP) Internet browser. V70 telephones
incorporate a simplified icon and list-based user interface (UI) for easier operation,
allow short message service (SMS) text messaging, and include clock, alarm,
datebook, calculator, and caller profiling personal management tools. The PF 23 is
a single band phone that allows roaming within the GSM 1900 MHz band
V70 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, 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.
The telephones are made of polycarbonate plastic with a metal enclosure. The
display and speaker, as well as the 16-key keypad, transceiver printed circuit board
(PCB), microphone, charger and headphone connectors, and power button are
contained within the rotator form-factor housing. The user-replaceable 600 mAh
nickel metal hydride (NiMH) battery provides up to 300 minutes of talk time with
up to 180 hours of standby time
module (SIM) cards which fit into the SIM holder next to the battery. These
telephones feature a 96 x 64 pixel 800 square millimeter high-resolution graphics
display and an internal antenna.
V70 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
