AMPS
Advanced Mobile Phone : a 1G standard which operates in the 800-900MHz-frequency band. It is still widely used in the United States.
Analog
The simple way to transmit speech, which is translated into electronic signals of different frequency /or amplitude. The first networks for mobile phones, as well as broadcast transmissions, were analog. Due to being longer established in some countries, analog networks may offer better coverage than digital networks, however analog phones are less secure suffer more from interference where the signal is weak. Analog systems include AMPS, NMT ETACS.
API
Historically, “application programming interface”. Practically, an API is any interface enables one program to use facilities provided by another, whether by calling program, or by being called by it. At a higher level still, an API is a set of functionality delivered by a programming , as such the mix of APIs in a particular tells you what can do.
Bluetooth
An open specification for seamless wireless short-range communications of data voice between both mobile stationary devices. For instance, it specifies how mobile phones, computers PDAs interconnect each other, computers, office or home phones. The first generation of Bluetooth permits exchange of data up to a rate of 1 Mbps per second, even in areas much electromagnetic disturbance. It transmits receives via a short-range radio link using a globally available frequency band (2.4 GHz ISM band).
bps
Bits per second: a way of quantifying data transmission throughput. It is the number of pieces of (bits) transmitted or received per second.
