An advanced type of radio transmission that broadcasts voice or data intact via radio waves, which allows for greater clarity, advanced features and more capacity. The industry uses three types of digital technology: TDMA, CDMA and GSM.
A call may be "dropped" or disconnected due to a dead or low-charged battery, faulty or poorly connected vehicular antennas, weather conditions or by driving out of a service area. Interference and varying levels of signal strength may also be experienced when traveling near the boundaries of a service area and in enclosed structures such as parking garages, tunnels and elevators.
Electronic Serial Number. The unique number assigned by the manufacturer and encrypted on the microchip of a particular wireless phone. This number is entered into the MTSO and used to identify and track that specific wireless phone. The ESN can be compared to a Social Security number for a U.S. citizen.
A button on a wireless phone that, when pressed, disconnects the call.
A costly problem in the wireless telecommunications industry whereby a user intentionally adjusts a wireless phone in order to make and receive phone calls without paying for them. Fraud has virtually been eliminated in the system that Airpeak Communications runs.
A certain "size" of radio wave: The rate at which the electric and magnetic fields of a radio wave vibrate per second.
Formerly identified the Groupe Speciale Mobile of the European Telecommunication
Standards Institute (ETSI); today it is a worldwide standard. Today it has
come to be known as Global System for Mobile communication. A public all-digital
cellular network using TDMA techniques for multiplexing and using a transmission
band. A GSM network can provide, besides telephony services, short messaging
services (SMS) and data communication, in circuit- and/or packet mode.
Another term for "speaker phone." Hands-free kits can make wireless phones safer to use while driving and doing other activities.
The transfer of a wireless phone call from one cell site to the next, as a vehicle travels between cells.
The device on a wireless phone that has the receiver, the key pad and the display.
Home Service Area
The area where a customer makes and receives local calls, and the bill for wireless service is generated. Also called the "local market."

A traditional phone used in businesses and homes with service provided by the local telephone company.
A special key on the handset that, when pressed, prevents any caller from making outbound calls; used as a security measure to prevent unauthorized use of the wireless phone.
Mobile Identification Number. A wireless phone's 10-digit "phone number."
Mobile or Car Phone
A mobile phone is an installed cellular car phone. Since it draws power from the car's battery, battery life is extraordinarily long and talk time is virtually unlimited. Its external antenna offers the best possible reception, and can be mounted on the roof, trunk or any window.
Mobile Telephone Switching Office. The central office computerized switching equipment that coordinates and controls the routing and completion of calls in a cellular system. The MTSO connects the cellular system to the wired telephone network.
A red light on a wireless phone that illuminates when the phone is in an area where no wireless service is provided.
Non-business hours for wireless use, usually evenings and weekends. (Nevada
Wireless tailors its rate plans for Heavy Peak usage to benefit its business
Personal Communication Service. Originally meant to describe digital service offered at a higher frequency than cellular, it is now used as a generic term for all digital wireless.
Primary business hours for using wireless service,
often between 7 a.m. and 7 p.m. Peak times vary by market and by carrier.
The smallest type of wireless phone also known as a handheld phone. Weighing as little as 4 ounces, it offers the most flexibility and convenience, easily carried in a pocket, purse or briefcase. A portable phone has a built-in antenna, and is powered by an attached, rechargeable battery that provides approximately 45 to 100 minutes of talk time, depending on the type of battery used.
A button on a wireless phone used to connect (or send) a call once the caller dials an outbound number.
The fixed amount a customer pays each month to receive the service, regardless of how often or how little the wireless phone is used. The exact monthly fee depends on the particular calling plan chosen by the customer.
A gauge of the strength or weakness of a wireless phone's reception to cellular transmission for a specific cell at a specific geographical location. Signal strength (strong or weak) impacts call quality and call completion.
The amount of time you can leave your fully-charged wireless phone turned on before the phone's battery will run down.
The length of time you can talk on your wireless phone without recharging its battery. A phone's battery capacity is usually expressed in terms of "minutes of talk time" or "hours of standby time." When you're talking, the phone draws more power from the battery.
Time Division Multiple Access. A digital cellular transmission method that divides amounts of time on a single radio frequency into parts, then assigns a different phone conversation to each part. This allows a larger number of people to use the cellular system at any one time.
Also known as a bag phone, this is a 3-watt wireless phone with some of the features and benefits of both a mobile and a portable phone. When used in a car, a transportable phone can be plugged into the vehicle's cigarette lighter for power. Since it's not permanently installed in a car, it can be moved and used in different vehicles. Though heavier and bulkier than a portable phone, it functions like a portable when powered by its attached battery.
Voice Mail or Voice Messaging
A "telephone mailbox" that answers a call, plays a greeting and records a message when you're away from the phone or are currently using the phone. After you have retrieved your messages, you can delete them, save them, reply to them or forward them to someone else (or a group of people) on your voice mail system.
