Radio communication equipment and method used in said equipment
First Claim
1. A radio communication equipment comprisinga first antenna;
- a first RF unit for wireless communication, the first RF unit being connectable to said first antenna, wherein a first frequency band is used by said first RF unit for reception of a signal via said first antenna and a second frequency band is used by said first RF unit for transmission of a signal via said first antenna, said first and second frequency bands being used alternatively by said first RF unit;
a second RF unit for wireless communication, the second RF unit being connectable to said first antenna, wherein a third frequency band is used by said second RF unit for reception of a signal and a fourth frequency band is used by said second RF unit for transmission of a signal, said third and fourth frequency bands being used simultaneously by said second RF unit;
a third RF unit for wireless communication, the third RF unit being connectable to said first antenna, wherein a fifth frequency band is used by said third RF unit for reception of a signal via said first antenna and a sixth frequency band is used by said third RF unit for transmission of a signal via said first antenna, said fifth and sixth frequency bands being used alternatively by said third RF unit;
a second antenna, said second RF unit being simultaneously connectable to both the first antenna and the second antenna and reception of a signal being performed by said second RF unit via either the first or second antenna and transmission of a signal being performed by said second RF unit via the other of the first and second antenna; and
a band-pass filter connected to said first antenna, said band-pass filter automatically transmitting a signal belonging to a predefined frequency range to said third RF unit and automatically transmitting a signal belonging to a frequency range of a frequency higher than said predefined frequency range to said first or second RF units.
