The CISAR Italian Center for Radio Activities collaborated with LigoWave’s partner in Italy—Telcomms Srl—on testing a long-distance RapidFire link. LigoPTP RapidFire 5-N wireless bridges were installed in Monte Amiata (Tuscany, local site) & Monte Limbara (Sardinia, remote site), 304km apart over the Tyrrhenian Sea.
CISAR experiments with wireless technologies, connecting FM & digital repeaters & providing support for the radio community. After successfully inter-connecting Italy, CISAR aims to build a new wide-band digital network. The 304km link is especially important because it provides an alternative communications channel in emergency situations.
The LigoPTP RapidFire was chosen because it is equipped with the W-Jet proprietary protocol, an efficient 1.2GHz CPU, & high-power 31dBm 2×2 MIMO radios, meaning that it will not only establish a stable connection, but it will also ensure relatively high throughput despite the extremely long distance & oversea environment.
Multiple tests were performed with the RapidFire link, providing remarkable results: over the 304km distance, 20MHz channel throughput & PPS rates peaked at 54Mbps & 105,426PPS respectively, while 40MHz channels achieved 100Mbps & 90,719PPS. RapidFire wireless bridges ensured comparatively high throughput & packet delivery despite the long distance.
