pertaining to a small bandwidth; pertaining to the frequency allocated for mobile and radio services in the USA
Traditionally, a channel with bandwidth less than or equal to one voice-grade line With advances in network technology, narrowband has come to be associated with any channel operating at less than 1 544Mbps, such as Narrowband ISDN (NISDN) Contrast with Broadband and Wideband
In communications, a voice-grade transmission channel of 2400 bits per second or less
1) In data transmission, a limited range of frequencies 2) More specifically, a network in which data transmission speeds range from 50 bps to 64 kbps
Generally, narrowband describes telecommunication that carries voice information in a narrow band of frequencies (See 134)
A classification of the information capacity or bandwidth of a communication channel Narrowband is generally taken to mean a bandwidth of 64kbit/s or less
Communication technologies with a data transmission capacity of under 300 Kbit/s Includes online interactive services (e g Internet), voice, facsimile services, slow-scan video images and low-rate data transmission
a telecommunications medium, such as copper wire or part of a coaxial cable channel, that uses (relatively) low frequency signals Generally speaking, narrowband transmissions go up to 1 544 Mbps
The opposite of broadband A dialup or ISDN internet connection can be described as narrowband
A communications channel that transmits voice, facsimile or data at rates less than broadband systems
A communications channel of restricted bandwidth, often resulting in degradation of the transmitted signal
Used to describe a connection over a computer network which supports a relatively low bit rate Also sometimes used to describe content optimized for such connections
Narrowband refers to relatively low-speed methods of accessing the Internet, such as a ordinary telephone line and modem Broadband refers to high-speed methods of accessing the Internet, like ISDN and cable modems
1 A restricted frequency band, usually for a single user or used for a single purpose 2 A range of frequencies contained within a braodband 3 A communications channel that can carry data from 50 bps to 64 Kbps
A signal where the transmission bandwidth is on the order of its information bandwidth
a service or connection allowing only a limited amount of information to be conveyed, such as for telephony This compares with broadband, which allows a considerable amount of information to be conveyed
