Field tests aimed at the:
- control and monitoring of the rearrangement of the 900 MHz band;
- control and monitoring of the progressive release of a 5 MHz block;
- assessment of the quality of GSM users in refarming scenarios at 900 and 1800 MHz
Efficient use of radio resources through land defragmentation of the 900 MHz band, bunched in adjacent bands allocations to different managers.
Protection of users (included M2M devices) capable to operate only on the GSM system by measuring the quality of service before and after the refarming of the 900 MHz or 1800 MHz.
Availability of frequencies below 1 GHz for all the network operators and introduction of 3G technologies.
The project is part of the reorganization plan of the 900 MHz band, as issued by AGCOM Resolution no. 541/08/CONS and by the statement of the MISE of 11 February 2009, which approved the roadmap for the reorganization of the band proposed by mobile operators.
With the Communication of 31 July 2009, the MISE committed the Foundation for technical, scientific, operational, logistical and communication support in the implementation of the plan. In October 2009, FUB has therefore established a Working Group with the three GSM operators and the MISE for the assessment, control and monitoring of the reorganisation plan. The first phase of the plan dealt with the rearrangement of the 900 MHz band so to defragment spectrum allocations over the landscape and recompact in contiguous blocks bands assigned to different operators. FUB has carried out a measurement campaign to verify that GSM operators (TIM, Vodafone, WIND) operated only on channels in their assigned bands. Measurements were carried out in several cities.
The second phase includes the gradual liberation, on a territorial basis, of a 5 MHz block, to be fully achieved all over Italy by 31 December 2013. Interference levels were assessed in provincial areas where the block had been made available for the forth 'new entrant’ operator.
Another part of the activity focused on the identification of audit and control methodologies to be implemented following the refarming of the GSM 900 MHz and 1800 MHz. Quality parameters were evaluated (droppinb and blocking probability) before and after the refarming. Parameters have been assessed from the network counters and then validated through sample data collected on the field.
