Abstract
A method and related apparatus for transferring data between a mobile communication unit and a plurality of access points, wherein each of said plurality of access points and said mobile communication unit is provided with a transceiver, said mobile communication unit being arranged to travel a predetermined route, the method comprising: adjusting transmission power of at least the transceiver of the mobile communication unit substantially to a maximum level; and attenuating transmission signal of each transceiver such that signal level of a received signal in a transmission between the mobile communication unit and each of the access points is more optimal, wherein the level of attenuation is set constant at least in the mobile communication unit.

A method for transferring data between a mobile communication unit and a plurality of access points, wherein each of said plurality of access points and said mobile communication unit is provided with a transceiver, said mobile communication unit being arranged to travel a predetermined route, the method comprising:
- adjusting transmission power of at least the transceiver of the mobile communication unit substantially to a maximum level;
- and
- attenuating transmission signal of the transceivers of said plurality of access points and said mobile communication unit such that Signal-to-Noise Ratio (SNR) in a transmission from the mobile communication unit to each of the access points is over 25 dB and the SNR in a transmission from the access points to the mobile communication unit is not higher than 10 dB,
- wherein the level of attenuation is set constant at least in the mobile communication unit.
A wireless offload system for transferring data between a mobile communication unit and a plurality of access points, wherein each of said plurality of access points and said mobile communication unit is provided with a transceiver, said mobile communication unit being arranged to travel a predetermined route, wherein
- transmission power of at least the transceiver of the mobile communication unit is arranged to be adjusted substantially to a maximum level;
- transmission signal of the transceivers of said plurality of access points and said mobile communication unit is arranged to be attenuated such that Signal-to-Noise Ratio (SNR) in a transmission from the mobile communication unit to each of the access points is over 25 dB and the SNR in a transmission from the access points to the mobile communication unit is not higher than 10 dB,
- wherein the level of attenuation is constant at least in the mobile communication unit.
A mobile communication unit of a wireless offload system, said mobile communication unit comprising a transceiver, and said mobile communication unit being arranged to travel a predetermined route, wherein
- transmission power of the transceiver of the mobile communication unit is arranged to be adjusted substantially to a maximum level;
- transmission signal of the transceiver is arranged to be attenuated such that Signal-to-Noise (SNR) is over 25 dB, wherein the level of attenuation is constant.
