Definitions

Advanced intelligent networks
Systems that allow a wireless user to make and receive phone calls while roaming in areas outside the user's "home" network. These networks, which rely on computers and sophisticated switching techniques, also provide many Personal Communications Services features such as "one person/one phone."
Air Time
Actual time spent talking on the cellular telephone. Most carriers bill customers based on how many minutes of air time they use each month.
Alphanumeric
A message or other type of readout containing both letters ("alphas") and numbers ("numerics"). In cellular, "alphanumeric memory dial" is a special type of dial-from-memory option that displays both the name of the individual and that individual's phone number on the cellular phone handset. The name also can be recalled by using the letters on the phone keypad. By contrast, standard memory dial recalls numbers from number-only locations.
American National Standards Institute (ANSI)
A private organization that develops widely accepted standards for many pieces of modern day equipment.
Analog Technology
The traditional method of modulating radio signals so that they can carry information. AM (amplitude modulation) and FM (frequency modulation) are the two most common methods of analog modulation. Voice messages are electronically replicated and amplified as they are carried from the transmitting antenna to the receiving antenna. A problem with this technology, however, is that the amplification procedure tends to pick up "noise," sometimes making the message difficult to hear. Traditionally, cellular phones have utilized analog transmission signals.(See "Digital Technology")
Antenna
Any system of wires, poles, rods, reflecting discs, or similar devices used for the transmission or reception of electromagnetic waves.
Antenna Array
A group of antenna elements on the same geometric plane.
Antenna, Commercial
An antenna in any zoning district used in conjunction with a business, commercial enterprise, trade, calling, vocation, profession, occupation or means of livelihood, whether or not carried on for gain or profit, including, but not limited to public utilities, wireless telephone communications or privately owned or publicly supported AM or FM radio stations not otherwise exempt from the provisions of the Zoning Ordinance, cable television operations or television broadcast stations, but excluding FCC licensed amateur radio stations and standard television receive only (TVRO) non-parabolic antennas.
Antenna, Concealed
Also called disguised, camouflaged, "stealth" antennas, etc. These antennas are blended into the environment so as not to be seen or recognized. They include architecturally screened roof-mounted antenna, façade-mounted antenna as design features, "tree" poles which may appear to be palms or pines, clock towers, entry statement signage, and other types of concealment.
Antenna, Directional
Flat rectangular panels that typically don't exceed six square feet (6sf) [.5m2] with a maximum six feet (6') [2m] in length and two feet (2') [.5m] in width, and are typically, but not always, mounted to a triangular support structure atop a wood pole or steel monopole. Typically fifteen (15) panel antennas are required for each cellular facility. They can be exposed or concealed behind a radome cover.
Antenna, Dish (See Antenna, Parabolic)
Antenna Element
Individual components of an individual antenna.
Antenna, Groundmounted Parabolic
A parabolic antenna, the weight of which is fully or partially supported by an approved platform, framework, pole, or other structural system, which system is affixed or placed directly on or in the ground.
Antenna Height
The distance from the grade of the property at the base of the antenna or, in the case of a roof-mounted antenna, from the grade at the exterior base of the building, to the highest point of the antenna and its associated support structure when fully extended. The vertical distance between the highest point of a parabolic antenna when actuated to its most vertical position and the grade below, for a groundmounted parabolic antenna, and to the roof below for a rooftop parabolic antenna.
Antenna, Microwave Relay Parabolic
A transmitting and receiving antenna, typically parabolic, disc or double convex shaped with an active element external to the disc. that communicates by line of sight with another similar antenna or a geosynchronous orbiting satellite.
Antenna, Noncommercial
A television receive only (TVRO) parabolic or nonparabolic antenna in any district.
Antenna, Non-Roof-Mounted (NRMA) (See Antenna Structure, Free-standing)
Antenna, Nonparabolic
An individual array or group of arrays used to transmit and/or receive electromagnetic signals, including, but not limited to radio waves related to amateur radio stations licensed by the Federal Communications Commission (FCC) and microwaves related to wireless telephone communications.
Antenna, Omnidirectional
Cylindrical shaped antenna which transmits and receives in 360 degrees. This antenna typically does not exceed three and one-half inches (31/2") [9cm] in diameter and ranges from two feet (2') [.5m] to fifteen feet (15') [4.5m] in height. Also called "stick antenna" and "whip antenna."
Antenna Parabolic
A parabolic, semi-parabolic, disc, convex or double-convex shaped accessory structure, including, but not limited to, a main dish and covering, feedhorn, receiving element, structural supports and all other components thereof, which transmits and/or receives television signals or electromagnetic waves by line of sight with another similar antenna or a geosynchronous or orbiting satellite. Because of their shape and function, they are often also called "dish" antennas, microwave dishes, and satellite dishes.
Antenna, Roof-Mounted (RMA) (See Co-location)
Antenna, Satellite
Any antenna used to receive and/or transmit radio or television signals from orbiting communications satellites.
Antenna, Satellite Earth Station
A parabolic or dish-shaped antenna or any other apparatus or device that is designed for the purpose of receiving radio waves.
Comment: Many local ordinances have attempted to control the location and size of satellite antennas for aesthetic reasons. Recent court cases have ruled that Federal Communications Commission (FCC) regulations have preempted local control over these devices or at least require them to be treated as any other antenna (Alsan Technology v. Zoning Board of Adjustment, 235 N.J. Super. 471; Nationwide v. Zoning Board of Adjustment, 243 N.J. Super. 18).
Local control of satellite antennas may be upheld if the local ordinance is crafted to meet the following three-point test:
  1. The ordinance should not differentiate between satellite dish antennas and other types of antennas;
  2. There should be a reasonable, clearly defined health, safety, and/or aesthetic objective as the basis for the ordinance; and
  3. The ordinance should not impose unreasonable limitations on reception or impose costs on the user disproportionate to total investment in antenna equipment and installation.
Antenna Satellite Uplink
A commercial parabolic antenna which receives and transmits electromagnetic waves by line of sight with geosynchronous orbiting satellites.
Antenna Structure
An antenna array and its associated support structure, such as a mast or tower, but not to include a suspended simple wire antenna, that is used for the purpose of transmitting and/or receiving electromagnetic signals, including but not limited to radio waves and microwaves.

California State Public Utilities Commission (CPUC)
The CPUC regulates those telecommunications which are also considered public utilities. Where the telecommunications service being provided is a public utility, such as telephone service, including local, long distance or cellular telephone service, then those services fall under CPUC jurisdiction.
California Telecommunications Industry Association (CTIA)
An organization for private sector telecommunications service providers.
Cell
The basic geographic unit of a cellular system. Also, the basis for the generic industry term "cellular." A city or county is divided into smaller "cells," each of which is equipped with a low-powered radio transmitter/receiver. The cells can vary in size depending upon terrain, capacity demands, etc. By controlling the transmission power, the radio frequencies assigned to one cell can be limited to the boundaries of that cell. When a cellular phone moves from one cell toward another, a computer at the Mobile Telephone Switching Office (MTSO) monitors the movement and at the proper time, transfers or hands off the phone call to the new cell and another radio frequency. The handoff is performed so quickly that it's not noticeable to the callers.
Cell Sites
  1. Capacity Site

    Shorter telecommunications structures that cover smaller areas with a more concentrated demand. Capacity sites serve to increase the capacity when surrounding sites have reached their practical channel limits.

  2. Coverage Site

    Higher telecommunications structures covering a larger geographic area, but with a lower service demand. Coverage sites serve to expand coverage in large areas or in areas with difficult terrains and to enhance coverage for portable systems. Coverage sites allow users to make and maintain calls as they travel.

  3. Transition Site

    Transition sites are needed for frequency re-use. Tall monopoles create a problem in frequency re-use because they "see" everything. In order to control frequency re-use problems, these tall sites must be removed and replaced temporarily by transition sites. Transition sites allow the cellular company to increase capacity and maintain coverage simultaneously.

Cellular
Common carrier mobile telephones operating in the 850 MHz region.
Cellular Carriers Association of California (CCAC)
Organization devoted to cellular issues in California.
Cellular digit Packet Data (CDPD)
Technology that allows data files to be broken into a number of "packets" and sent along idle channels of existing cellular voice networks.
Cellular Geographical Service Area (CGSR)
The actual area in which a cellular company provides cellular service. This area may be somewhat smaller than the MSA surrounding it.
Cellular Service
Two-way voice and data communications through hand-held, portable, and car mounted phones. Geographic coverage areas for cellular service are very large, and can cover cities, counties, and entire states.
Channel
A path along which a communications signal is transmitted.
Code division multiple access (CDMA)
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.
Co-location
  1. Siting multiple antenna structures within the same local area. Also called "antenna farms."
  2. Multiple antennas attached to an existing or proposed freestanding antenna structure. Also called donor sites and "piggy-backing."
  3. Roof-mount antenna (RMA) attached to the top of a building or other structure.
  4. Façade-mount in which the antenna is attached to (an) exterior wall(s) of a building or other structure.
  5. Enclosed in which the antenna facility is entirely contained within a building primarily occupied by another permitted use. Types 3, 4, & 5 are tenant improvements (TI).
Co-location Issues
Co-location may be problematic to accommodate the following technical, service and aesthetic concerns.
  1. Co-location may create signal interference both horizontally and vertically requiring additional area or height. Twenty feet (20') [6m] is the ideal platform separation, and the cumulative effect of adding multiple platforms (beanstalk effect) may have a more significant aesthetic impact than individual sites.
  2. Antenna structural design may not allow additional weight or wind loads from future antennas without significant modification and potential visual impacts.
  3. The more aesthetically treated monopoles do not have external handholds and attachments for servicing. To service these antennas, the entire structure must be lowered. Maintenance and repairs to one antenna would also disrupt service to the other telecommunications system(s).
  4. In the permitting of the original site, it may not be infeasible to plan for future co-location. How many sites per location? How many antennas per structure? How high a structure to accommodate multiple antennas? This is further complicated by terms of the master lease.
  5. Liability concerning personnel injury or antenna damage becomes an issue with shared sites.
  6. Whereas single antenna structures may be visually attenuated, an antenna "farm" or "forest" could have a more significant visual impact.
  7. Multiple users will have compounded problems in adapting to new technologies.
Commercial Mobile Radio Service (CMRS)
The regulatory classification that the FCC uses to govern all commercial wireless service providers including Personal Communications Services, cellular and Enhanced Specialized Mobile Radio.
Data Service
The electronic transfer of data or digital information.
Digital Technology (See Analog Technology)
Data (including voice messages) are converted into digits that represent sound intensities at specific points in time. Because natural pauses in the conversation are eliminated, (1) the background noise that is generally heard in the analog system becomes inaudible, and (2) more capacity becomes available from the same amount of spectrum, thus reducing the need for new sites. There are two forms of digital technology: 1) Code Division Multiple Access (CDMA) and 2) Time Division Multiple Access (TDMA). Both of these forms of digital technology render multiple access over one frequency, or channel.

Electromagnetic Fields (EMFs)
Though often referred to as radiation, EMFs do not actually radiate out from a source. Rather, they are best described as local electric and magnetic fields that envelop the surrounding space. The most ubiquitous source of EMFs is from the movement and consumption of electric power-transmission lines, household appliances, electronic devices, and lighting. (See Non-ionizing Electromagnetic Radiation)
Electronic Serial Number (ESN)
Each cellular phone is assigned an ESN, which is automatically transmitted to the base station every time a cellular call is placed. The Mobile Telephone Switching Office (MTSO) checks the ESN to make sure it is valid, that the phone has not been reported stolen, that the user's monthly bill has been paid, etc., before permitting the call to go through.
Enhanced Specialized Mobile Radio (ESMR)

Federal Aviation Administration (FAA)
The FAA also has a limited role in the regulation of telecommunications tower sites. Their review focuses on the height and location of towers to prevent interference with aircraft operations.
Federal Communications Commission (FCC)
The federal government agency that licenses most radio services. FCC regulations supersede some of the authority of local jurisdictions to regulate telecommunications facilities. The FCC has primary regulatory control over telecommunications facilities through its powers to control interstate commerce and specifically through the Federal Communications Act which established the FCC to provide a comprehensive national system to regulate radio frequency transmissions and related facilities. [FCC Rules and Regulations: Part 90 (Abridged) Private Land Mobile Radio Services.]
