Motorola A780 telephones feature global system for mobile communications (GSM)
air interface, general packet radio service (GPRS) transport technology, enhanced
Date Rate for Global Evolution (EDGE) and wireless application protocol (WAP)
Internet. The A780 incorporate a new user interface (UI) for easier operation, allows
short message service (SMS) text messaging, and includes personal information
manager (PIM) functionality.
The A780 is a quad-band phone that allows roaming within the GSM 900 MHz,
(DCS) 1800 MHz digital cellular system, the GSM 850 MHz, and PCS 1900 MHz
bands.
A780 telephones support GPRS, SMS and EDGE in addition to traditional circuit
switched transport technologies.
A780 telephones have a clam form factor. They are made of a polycarbonate plastic
with the earpiece speaker located in the flip. The flip features a viewing window
that allows a portion of the display to be seen with the flip is closed. The bottom
part of the clam (front housing) contains the touch screen display, main printed
circuit board (PCB), microphone, external accessory connector, infrared (IR)
communications port, and headset jack. Also located in the front housing are the
voice, volume, power, page up, page down, and menu buttons, as well as the battery,
antenna, subscriber identity module (SIM) holder, and status light. A stylus, also
located in the front housing, is provided to aid manipulating the touch screen UI.
The standard 1000 mAh Lithium Ion (Li Ion) battery fits behind a removable back
cover.
The phone accepts both 1.875V and 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.
A780 telephones use advanced, self-contained, sealed, custom integrated circuits to
perform the complex functions required for GPRS/EDGE communication. Aside
from the space and weight advantage, microcircuits enhance basic reliability,
simplify maintenance, and provide a wide variety of operational functions.
