Optically Beam-formed Antennas For Adaptive Broadband Fixed And Mobile Wireless Access Networks

Cel

Broadband multimedia services supported by 40 GHz fixed and mobile access networks require high-performance, high reliability and low unavailability wireless links. Natural and man-made performance impairments (e.g. intensive rainfalls and provisional obstacles intercepting the line-of-sight radio link) severely limit the QoS of such broadband multimedia services. OBANET project addresses efficient coverage area management strategies and control protocols to optimise the QoS and spectrum resources in wireless access scenarios. To this end, high performance optically beam-formed base station adaptive antennas are proposed to implement such management strategies. Photonic integrated beamformers, based on telecom-market-oriented optical chips, are developed and such efficient coverage area management strategies are evaluated on a laboratory platform for fixed and mobile radio access.

Objectives:
OBANET project aims at studying, proposing, implementing and evaluating specific coverage area management strategies as well as their associated technologies for performance optimisation in broadband adaptive wireless access networks in two scenarios: fixed and mobile broadband radio accesses at 40 GHz frequency band. Optically beamformed base station antennas are envisaged to address dynamical changes in the network features and resources (e.g. coverage areas and spectrum sharing in the sectorised area) in order to overcome the service unavailability arising from man-made (e.g. provisional obstacles intercepting the radio link) and natural impairments (e.g. intensive rainfalls in some parts of the service areas). High-performance optoelectronics devices and photonic integrated circuits composing the optical beamformer are developed.

Work description:
Obanet project main objective is to overcome QoS limitations due to natural man-made impairments in fixed wireless access networks operating at the 40 GHz frequency band. Coverage area management strategies and network control protocols as well as optoelectronic associated technologies are demonstrated and evaluated. OBANET project tasks may be grouped in three main workpackages: systems aspects, optoelectronic technologies and evaluation platfoms.
- System aspects: specification of the overall network concept using optically beamformed base station antennas; development and software implementation of different specific coverage area management strategies and control/monitoring protocols for fixed radio access (e.g. to overcome natural and man-made performance degradation mechanisms, to optimise the network capacity by readily managing the coverage areas in different phases of network deployment, multiple access based on base station antenna beam division).
-Technology aspects: development of a photonic integrated beamformer for fixed and mobile access, high-performance packaging of photonic integrated beamformers, development of optoelectronic subsystems required to test and performance evaluation of integrated beamformers, etc.
-Evaluation platforms: two evaluation platforms will be built up.
-Discrete beamformer architecture: using commercial-off-the-shelf technology different beamformer architectures for single and multiple beam antennas will be evaluated.
--Fixed and mobile access beamformer: management strategies for fixed and mobile access scenarios will be evaluated on the photonic integrated beamformer prototype at the 40 GHz platfom.

Milestones:
Among all the project milestones the principal ones ares:
M04: System conception and specification,
M12: coverage area management strategies and control/monitoring network protocols implemented,
M21: critical parameters in the beamforming structures determined,
M30: Fixed beamformer final prototype delivered,
M34: Fixed beamformer prototype evaluated (test of management strategies),
M36: project finished and results disseminated.
