China Petroleum is the largest oil and gas supplier in China and is the fourth – greatest crude producer in the world. Fully and efficiently allocated China’s Petroleum resources are the result of constant investment to R&D and a strong focus to QA. By solving China’s Petroleum technical challenges in their surveillance infrastructure LigoWave established a partnership with a serious player in the oil and gas industry. LigoWave is a reliable partner and offers a strong Carrier – Grade product portfolio with
emphasis on durability and reliability.
At the moment, the LigoWave equipment is used to surveil the oil extraction process on the middle-sized oil platforms’ field of China Petroleum. The 1080P videos are streamed from the cameras to the centre where all the data is managed. The cameras are installed directly on the oil field. The main requirement from the client was to ensure smooth video streaming without any transmission loss or video lag. The LigoBase 5 – 90 was installed as a base station together with an integrated 17dBi 90 degrees sector antenna. LigoSU 5-20 and LigoSU 5-23 were connected to the LigoBase. Every LigoSU was connected with a 1080P camera through an Ethernet port. The cameras were from Dahua (model: DH-SD-6A9226H-NHI) or Hikvision (model: DS-2DF5120IW). The distance from the LigoBase station to the LigoSUs was 2 – 4 km.

The print screen above shows the throughput graph and the PPS transfer records from LigoBase for a 1 day period. The throughput during a one day period was stable, reaching above 30 Mbps on average of video data. It is a really good result considering the fact that the LigoBase was installed on a tower, which was heavily crowded with other devices. A noisy environment is always a challenge to sustain the stable throughput for video traffic, however, the LigoWave proprietary W-Jet V protocol is an ideal solution for that kind of situation, since it is designed to maximize throughput and packets per second while at the same time it helps to minimize latency.
