The great idea dealing with radio transmission path of the GSM system is the explosion sequence (simplified as Burst). This is a series of transfer units, including over 100 bits configuration. The sequence explosion of limited duration and occupies a limited radio spectrum. Can be described as the output of the time and frequency window. This window is called Slot. In other words, within the frequency range of the system, the central frequency of each slot is defined 200KHz (observed in terms of FDMA)? While the socket is circular, as the time progresses, which occupies 15/26ms (i.e. approximately 0.577ms) each time (observed in terms of TDMA). The periods of these slots are called slots and the duration of which is called the unit of time (defined as BP, indicating the period Burst).
We can use a time / frequency diagram to draw the groove small rectangles having a length and a width 15/26ms than 200 kHz, as shown in the above diagram. Similarly, we can call the 200 kHz bandwidth specified in the GSM, the frequency slot, which corresponds to the radio frequency channel (i.e. RF channel) of the GSM specifications.
The two conditions: time and sequence explosion are different to some extent in the same application. For example, the burst sequence is sometimes associated with the time-frequency "rectangular" unit and sometimes the contents. Similarly, the timing is the concept of value of time or This shows a slit in each 8 slots used periodicaly.
To use a specific channel to broadcast the eruption sequence to the specified torque and frequency, ie, the specified slot. Generally, the time slots in a channel is discontinuous.
