Solution: Communicating to the Moving Vessel with Broadband Wireless
In a single-carrier system, the signal varies due to reflection and ducting. However, the reflection is used to advantage in PTP equipment by deploying vertically separated antennas at one or both ends of a link, creating two radio paths that don’t experience reflection and ducting at the same time. By optimally combining the separate transmissions, this equipment eliminates signal cancellation and maximizes the signal received in each direction.
PTP equipments have successfully established connections to moving ships at distances up to 20 miles (32 km). Such challenging deployments are successful due to the high system gain of powerful radio transmitters and super-sensitive receivers, adaptive modulation, and built-in spatial diversity that reduces the effects of ducting and water reflection. In addition, the rotation and movement of the ships relative to the land normally dictates the use of omni-directional or sector antennas, depending on the specific application.
With solutions that offer cost-effective, digital communications at carrier-class reliability – up to 99.999% – and provide throughput rates from 3 Mbps up to 300 Mbps, PTP is combined these innovative technologies that are proven to minimize interference and maximize throughput:
