2G, or second generation, is still the most common type of wireless cellular communication in use, although cellular carriers are beginning to phase it out and move to 3G and 4G.
3G, or third generation, mobile communications has data rates of hundreds of kilobits per second to tens of megabits per second.
Fourth generation mobile communications features data rates of tens to hundreds of megabits per second. Future 4G data rates will exceed one gigabit per second.
One of two radio frequencies in use in the U.S. 850MHz frequencies are known for their ability to better penetrate buildings and structures to reach reception towers.
One of two radio frequencies in use in the U.S. 1900MHz frequencies are known for their ability to travel at faster speeds.
A measurement of the amount of data that can be sent over a connection in a given amount of time without distortion.
Companies that sell the use of a wireless network, which includes cell towers and the infrastructure linking them. Examples include AT&T, T-Mobile and Verizon, among others.
Mobile communication system that sends signals between a number of short-range radio stations, automatically switching as the user moves closer to or farther away from each.
A specific range, or band, of frequencies licensed by the federal government on which each cellular carrier operates their mobile services.
An inbound/outbound call center with operators that serve as liaisons between our customers and emergency personnel responding to an alarm.
Dual-band Units/Dual Frequency
Devices such as your home security control panel are dual-band units, or have dual frequency, meaning they are capable of using both 850MHz and 1900MHz frequencies.
The number of crests of a wave that move past a given point in a given amount of time. One Hz corresponds to one crest per second. As the wavelengths decrease as the frequencies increase (1900MHz), and as they increase so the frequencies decrease.
A bit, or binary digit, is a single, basic unit of computer-related information. A gigabit is approximately 1 billion bits.
The process of converting 2G frequencies to 3G frequencies in the time prior to the December 31, 2016 sunset deadline.
A bit, or binary digit, is a single, basic unit of computer-related information. A kilobit is approximately 1 thousand bits.
A bit, or binary digit, is a single, basic unit of computer-related information. A gigabit is approximately 1 million bits.
Herz, or Hz, is a measure of frequency per unit of time (cycles per second), most commonly used to describe radio and audio frequencies. 1 MHz is equal to 1 million Hz.
Transmission and reception of electromagnetic waves in the radio-frequency range, i.e. 850MHz or 1900MHz
The date that the carrier decides that the 2G network will cease to exist.
The time period between the present moment and the shutdown of the 2G network, which includes the gradual harvesting of frequencies.
Any system or device, such as a home security control panel or a cellular phone, used to transmit messages or signals by electromagnetic waves.
