Current consumption in 2G connected-mode 

When a GSM call is established, the VCC or 3.3Vaux module current consumption is determined by 
the current consumption profile typical of the GSM transmitting and receiving bursts. 
The  peak  of  current  consumption  during  a  transmission  slot  is  strictly  dependent  on  the  RF 
transmitted power, which is regulated by the network (the current base station). The transmitted 
power  in  the  transmit  slot  is  also  the  more  relevant  factor  for  determining  the  average  current 
consumption. 
If the module is transmitting in 2G single-slot mode in the 850 or 900 MHz bands, at the maximum 
RF  power  level  (approximately  2  W  or  33  dBm  in  the  allocated  transmit  slot/burst)  the  current 
consumption can reach an high peak (see the “Current consumption” section in the TOBY-L2 Data 
Sheet 

[1]

  or  the  MPCI-L2  Data  Sheet 

[2]

)  for  576.9 

µ

s  (width  of  the  transmit  slot/burst)  with  a 

periodicity of 4.615 ms (width of 1 frame = 8 slots/burst), so with a 1/8 duty cycle according to GSM 
TDMA (Time Division Multiple Access). 
If  the  module  is  transmitting  in  2G  single-slot  mode  in  the  1800  or  1900  MHz  bands,  the  current 
consumption figures are quite less high than the one in the low bands, due to 3GPP transmitter output 
power specifications. 
During a GSM call, current consumption is not so significantly high in receiving or in monitor bursts 
and is low in the inactive unused bursts. 

Figure 4

 shows an example of the current consumption profile versus time in 2G single-slot mode.
