Product Overview

Features

The Motorola C155 features a global system for mobile communications wireless interface and
general packet radio service (GPRS) transport technology. It also features a simplified icon and
graphical user interface (UI) for easier operation in addition to short message service text
messaging (SMS), speed dialing, quick dialing, an alarm, a calculator, games, and an address
book.
C115 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 21-key keypad, transceiver printed circuit board (PCB), microphone,
charger and headphone connectors, and power button are contained within the candy bar form-
factor housing. The user-replaceable 730 mAh Lithium-Ion (Li-Ion) battery provides up to 180
minutes of talk time with up to 250 hours of standby time. The phone accepts 3V mini
subscriber identity module (SIM) cards that fit into the SIM holder next to the battery. These
telephones feature a 96 x 64 pixel high-resolution color graphics display and an internal
antenna.
C115 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.
