As mentioned before, the system has to work in indoor and outdoor locations, and can be used in various 
transmission bands and channel bandwidths. This system is based on DVB-T and in order to have the 
maximal compatibility is important to describe the characteristics of DVB-H system: 
coverage classes, frequencies bands where it works, the most important losses to take into account as 
building penetration loss and vehicle entry loss.

4.1.5 Coverage Classes 
The hand-held terminal has to expect the reception under different conditions (terminal is moving, no line of 
sight,etc.). DVB-H services will be provided in these situations and defines now types of reception to make it 
possible: portable and mobile reception. When the reception is under conditions of no speed or very low 
speed is called portable antenna reception. Mobile antenna reception is defined for receptions at medium to 
high speed. 
Four different receiving conditions for portable and mobile reception are the defined: [9] 
1. 
Class A:
Hand-held portable outdoor reception. This class contains outdoor reception no less than 
1.5m above ground level at very low or no speed. The receiver is assumed to be portable with an 
attached or built-in antenna. 
2. 
Class B:
hand-held portable indoor reception at ground floor. This class contains indoor receptions 
no less than 1.5 m above floor level in rooms at very low or no speed. Reception on the ground floor 
and windows in the external walls of the building is assumed. The receiver is assumed to be portable 
with an attached or built-in antenna. 
3. 
Class C:
Integrated car antenna mobile reception. This class contains outdoor reception (no less 
than 1.5m above ground level) with a moving DVB-H terminal (an example is an antenna integrated 
in a car). 
4. 
Class D:
hand-held mobile reception. Includes terminals that are used within a moving vehicle, 
reception inside cars or vehicles. Receptions in no less than 1.5m above ground level is assumed. 
Coverage in small places, around 100 m

, is classified in two groups that makes possible the reception. If at 
least the 95% of the receiving locations of the area are covered for portable reception and the 99% are 
covered for mobile reception we are under a
