A novel method is presented to transport microwave signals over graded-index polymer optical fibre (GIPOF) networks feeding radio access points in high-capacity wireless LANs. It relies on optical frequency multiplying, by sweeping a laser wavelength over a number of free spectral ranges of a simple periodic optical filter at the access points. It enables a cost-effective system implementation, and easy upgrading by offering data signal transparency. Microwave frequencies at several tens of GHz carrying multi-point digital data signal constellation formats such as QPSK and QAM are achievable in GIPOF networks with a reach of several hunderds of metres.
