A BSS has to generate the frame structure, which starts and ends with a tail field, and which has a training sequence in the mid. This fields can be used for synchronization. Each mobile device is doing its own synchronization due to this field, which is important because of time multiplexing to avoid overlapping data transmission, but BSS also has an important task to do in the synchronization: to make guard times small, it measures the distance to each end of device and calculates timing advances.

Transactional Synchronization Extensions was created in 2012.
synchronizationif two alternators are running in parallel and excitation of one machine is increased,then its terminal voltage will change and there will be a synchronizing current.this machine will become generating and other will act as a motor .synchronizing torque will be developed which will retard the generating machine and will accelerate the motoring one till synchronization is achieved again.this will be confined to the local circuit only
current is load dependent,after synchronization only current will flow
Generally, synchronization refers to matching three parameters between an incoming Alternator and the existing busbar before connecting to the actual load. They are 1. Magnitude of voltage 2. Frequency 3. Phase sequence The voltage in the alterenator is matched by varying the excitation. The frequency is matched by varying the speed of the alternator by its prime-mover. The phase-sequence is matched by flipping any of the two phases if mis-matched. This can be achieved and ensured either by "Three dark lamps method" or using a synchonoscope.

GSM hosting provides the platform for gsm forums. To get more information there is a forum titled GSM hosting listed as the place to find the gsm forums.
In the context of Mobile phones gsm means Global System for Mobiles. Hoerver 100 gsm or 130 gsm is usually referred for thickness of paper. gsm means grammes per square meter. Hence 130 gsm is thicker than 100 gsm. Simple.
