China Airlines (CAL) wanted to build a redundant data backhaul link between the CAL airport office & their DaiYen support center. This link was planned to serve as a back-up solution, if the existing fiber-optic link was to fail.
The main challenge of setting up a data backhaul link in this area was the high level of noise & environmental interference in the 5GHz frequency spectrum. Hence, CAL needed a wireless network solution that would minimize these effects.
China Airlines chose LigoWave’s LigoPTP RapidFire 5-23 bridges. The point-to-point solution is equipped with the W-Jet protocol, which optimizes devices for better & more stable performance, & can deliver up to 54dBm EIRP, this way ensuring a stronger signal in noisy environment.
The distance between the master & the slave units was 2.6 kilometers. Performance averaged at 550Mbps of throughput over an 80MHz channel. The combination of 31dBm transmit power & 23dBi antenna gain guaranteed that the link stays up & running.
