Motorola V80 telephones feature global system for mobile communications (GSM)
air interface, general packet radio service (GPRS) transport technology, and
wireless application protocol (WAP) Internet. The V80 incorporates a color user
interface (UI) that is both icon and list-based for easy operation, allows Short
Message Service (SMS) text messaging, Enhanced Message service (EMS),
Multimedia Messaging Service (MMS), and includes personal information manager
(PIM) functionality. The V80 is a tri-band phone that allows roaming within the
GSM 900 MHz, digital cellular system (DCS) 1800 MHz, and personal
communication service (PCS) 1900 MHz bands.
V80 telephones support GPRS, SMS, EMS, and MMS 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 (GPRS). 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.
Multimedia messaging allows the end user to send photos along with personalized
voice messages.
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 rotator form-factor housing. The standard 750 mAh Lithium Ion (Li Ion)
battery fits behind the back cover.
The phone accepts 3V and 1.8V mini Subscriber Identity Module (SIM) cards which
fit into the SIM holder underneath the battery. The antenna is mounted internally.
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.
The phone also contains Bluetooth® technology for wireless connections to
Bluetooth enabled wireless speaker and headphone accessories.
V80 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 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
