To evaluate the feasibility of the amount of energy that can be purchased (energy harvesting) from the environment (where RF is radio frequency) in the vicinity of a GSM base station BTS and compliance permissible limits the transmission power, we performed measurements of the electromagnetic field intensity fixed located in the University (North University of Baia Mare Centre of Technical University of Cluj Napoca). The mobile phone system measurements are made to determine the electromagnetic field strength in dBm for each radio channel in the frequency spectrum of a base station BTS but it is useful to determine the power density of the electromagnetic field, which is expressed in W / m². For this reason the values measured in dBm are converting in W / m². For measured values seems that is posible to be enough energy from the environment to supply a sensor.
