a wireless phone that can operate on both the 1900 and 800MHz digital networks, and on the 800MHz analog network.
A tri-mode amplifier is when two channels of an amplifier are run independently for midrange/treble, but are also bridged for running a (sub)woofer. It is the same as bridging the amplifier, but you keep the midrange/tweeters on their respective channel outputs.
In the Wi-Fi context, tri-mode refers to devices which are 802.11b, a, and g-compatible. In the mobile context, tri-mode describes a cellular phone that is capable of using analog, digital and GSM frequencies. (See dual band). close
TriMode phone operates on two frequency bands, such as 800MHz and 1900MHz, as well as operating in both digital and analog networks. See also DualBand, DualMode.
(Wireless Phone Feature) A phone that operates not only on a local PCS (1900MHz) system but also on the widely available analog cellular system and in non-PCS (800MHz) digital cellular areas.
Cellular phones, which can operate on three frequencies: 1900MHz, 800MHz digital or 800MHz analog when digital is not available.
a.k.a. Triple Mode Triple Mode. Functionality that allows a mobile phone to transmit in three modes for wider coverage area. For example, a mobile phone may be equipped to use analog, 800 MHz cellular and 1900 MHz PCS frequencies to make and receive calls.
The term applied to a phone that works on 800 MHz analog, 800 MHz digital and 1900 MHz (also known as 1.9 GHz) frequencies.
Triple mode. A combined analog and digital mobile phone. Allows for service in the analog system frequency and in both digital frequencies.
A feature on some wireless handsets that allows it to operate on both digital and analog networks. In digital mode, a tri-mode handset can operate at two different frequencies, 800MHz and 1900MHz, offering the user greater coverage and quality of service than dual mode, single mode or analog handsets. The handset is programmed to automatically select, depending on availablility, digital (at 800MHz or 1900MHz) versus analog service to maximize quality of service for the user.
Phones that work on three modes GSM, TDMA and analog.
Wireless phone that offers both dual-mode and dual-band capability to increase opportunities for obtaining cellular service. Dual-mode allows the phone to access digital and AMPS (analog) channels. Likewise, dual-band enables a phone to operate on two digital frequencies. For example, a dual-band phone could operate on both 800MHz CDMA and 1900MHz CDMA digital networks. This is a network and subscription dependent feature--not available in all areas.
