Method of interference control and radio terminal equipment arrangement

The invention relates to a radio terminal equipment arrangement and to a method of interference control. The radio terminal equipment arrangement comprises: a cellular core unit and at least one peripheral unit, the cellular core unit being configured to communicate with a peripheral unit using a wireless low power radio frequency (LPRF) connection, a peripheral unit being configured to establish an outside LPRF connection to a unit other than the core unit. The core unit is configured to give a control command for adjusting the outside LPRF connection activity of the peripheral unit, when another LPRF connection needs to be established by the core unit; and the peripheral unit being configured to adjust the outside LPRF connection activity based on the control command received from the core unit.
