EMC Workshops: Presentation of AWE Communications
Here comes a part of the presentation of AWE Communications on the EMC Workshops.	____

Part A: Comparison GSM <=> DECT

In the first part, apart from a general introduction to radio networks in urban areas, a comparison between mobile communications networks and home DECT phones is made which shows that even in a worst case scenario the field strength from a penetrating base station is lower than the one of a DECT base station.

Part B: Number of base stations required for coverage

In the second part of the presentation it is shown that more base stations do not mean a higher load in terms of radiation to the public.

The first comparison shows that more base stations lead to a smaller maximum and mean value of the field strength but still result in a better coverage:


One central GSM 1800 base station mounted on the roof of a building at a height of 40 m. Transmit Power is 20 W, antenna gain is 13 dBi. Mean field strength in whole scenario: 3.1 mV/m	Applied scale	Seven GSM 1800 base stations mounted on roofs of buildings at heights of 15 to 30 m. Transmit Power is 2 W, antenna gain is 13 dBi. Mean field strength in whole scenario: 1.6 mV/m

Part C: Coverage Probability

The second comparison shows the coverage probability for both scenarios. Again, it is shown that the coverage is much better when using more base stations.

Part D: Less exposition due to more base stations for the same area

The third comparison looks at the required transmit powers of the base stations under the assumption that power control is performed. It shows that using more base stations further reduces the exposition of the public as the transmit power can be reduced far more. Due to the principle of reciprocity, also the transmit powers of the mobile terminals can be reduced, leading to an even smaller exposition of the public and especially of the users.
