光電波融合技術を用いたデュアルバンドマイクロ波帯無線アクセスシステムの検討

抄録

A Radio on Fiber (ROF) technique has a great potential in wireless communication systems. In this paper, we performed fundamental examination of microwave wireless access systems based on Radio on Fiber.
First, we designed and constructed examination systems applying dual band (2.4GHz and 5GHz) multi service transmission systems and confirmed to have sufficient performance by transmission experiment.
Then, application of FP-LD (Fabry Perot Laser Diode) was considered in order to reduce the system cost, and most degradation of the transmission characteristics was not observed when FP-LD was used.
Finally, BIDI (Bi-directional) module which integrated LD and PD within one package was made for further cost reduction. By measuring the transmission performance, applying BIDI module to ROF systems was shown to be effective.
