Useful Terms
AMPS (Advanced Mobile Phone Service): The term used by AT&T's Bell Laboratories
(prior to the break-up of the Bell System in 1984) to refer to its cellular technology. The
AMPS standard has been the foundation for the industry in the United States, although it
has been slightly modified in recent years. 'AMPS-compatible' means equipment
designed to work with most cellular telephones.
Analog: The traditional method of modulating radio signals so that they can carry infor-
mation. Analog is a method of representing information such that data points can vary
continuously, rather than only in discrete steps, as with digital modulation. AM (amplitude modulation) and FM (frequency modulation) are the two most common methods of
analog modulation. Though most U.S. cellular systems today carry phone conversations
using analog, some have begun offering digital transmission. See also Digital Modulation.
ANSI (The American National Standards Institute): A nonprofit, privately funded
membership organization that coordinates the development of U.S. voluntary national
standards and is the U.S. representative to non-treaty international standards-setting
entities including the International Organization for Standardization (ISO) and the International Electrotechnical Commission.
Antenna: A device for transmitting and/or receiving signals. The size and shape of
antennas are determined, in large part, by the frequency of the signal they are receiving.
Antennas are needed on both the wireless handset and the base station.
Authentication: A process used by the wireless carriers to verify the identity of a mobile
station.
Browser: Software that moves documents on the World Wide Web to your computer,
PDA, or phone. See HDML, HTML, HTTP and WML.
CDG (CDMA Development Group): A consortium of companies that have joined
together to lead the adoption and evolution of CDMA wireless systems around the world.
CDM: Customer Development Manager. Regional Nokia CDMA personnel for direct cus-
tomer contact with Carriers, formerly known as Field Marketing.
CDMA (Code Division Multiple Access): A spread-spectrum approach to digital
transmission. With CDMA, each conversation is digitized and then tagged with a code.
The mobile phone is then instructed to decipher only a particular code to pluck the right
conversation off the air. The process can be compared in some ways to an English-speaking person picking out in a crowded room of French speakers the only other person who
is speaking English. See also Digital Modulation.
Packet Data: Technology that allows data files to be broken into a number of 'packets'
and sent along idle channels of existing cellular voice networks.
Circuit Switched: A switching technique that establishes a dedicated and uninter-
rupted connection between the sender and the receiver.

holding the handset. An important safety feature.
HDML (Handheld Device Markup Language): A modification of standard HTML,
developed by Unwired Planet, for use on small screens of mobile phones, PDAs, and pagers. HDML is a text-based markup language, which uses HyperText Transfer Protocol
(HTTP) and is compatible with Web servers.
HTML (HyperText Markup Language): An authoring software language used on the
Web. HTML is used to create Web pages and hyperlinks.
HTTP (HyperText Transfer Protocol): The protocol used by the Web server and the
client browser to communicate and move documents around the Internet.
IM (Instant Messaging): A conversational interface across different platforms and sys-
tems via a wireless instant messaging server. Allows the user to send & receive messages
seamlessly.
IMSI (International Mobile Station Identifier): A number assigned to a mobile sta-
tion by the wireless carrier uniquely identifying the mobile station nationally and internationally. See also MIN, TMSI
Infrared: A band of the electromagnetic spectrum used for airwave communications
and some fiber-optic transmission systems. Infrared is commonly used for short-range
(up to 20 feet) through-the-air data transmission. Many PC devices have infrared ports,
called Infrared Serial Data Link (IRDA), to synchronize with other devices. IRDA supports
speeds up to 1.5 Mbps.

Transceiver NHP-2
Introduction
The NHP-2 is a CDMA DCT 4.0 engine incorporating IS-95B and IS-2000 features with
full 1XRTT data rate capacity. Advanced messaging features include SMS (MO/MT),
Instant Messaging, Nokia ‘Chat’ and Smart Messaging (ring tones, graphics, images, and
animations).
The standard internal battery (BLB-3) provides users with up to four hours of talk time
and 250 hours of standby time.
The transceiver has a full graphic display and the user interface is based on the Jack 3 UI
with two soft keys.
Both an internal and a whip antenna are used. When the whip antenna is in, only the
internal antenna is active. When the whip is retracted, both antennas are active. An
external RF connector also is used.
NHP-2 variants include:
• NHP-2AX (6385) tri-mode;
• NHP-2FX (6370) PCS; and
For additional variant information, refer to Chapter 5, Variants.
Operational Modes
There are several different operational modes: Modes have different states controlled by
the cellular SW. Some examples are: Idle State (on ACCH), Camping (on DCCH), Scanning,
Conversation, No Service Power Save (NSPS) previously OOR = Out of Range.
In the power-off mode, only the circuits needed for power-up are supplied.
In the idle mode, circuits are powered down and only the sleep clock is running.
In the active mode, all the circuits are supplied with power, although some parts might
be in idle state part of the time.
The charge mode is effective in parallel with all previous modes. The charge mode itself
consists of two different states, i.e. the fast charge and the maintenance mode.
The local mode is used for alignment and testing.
