Zhoushan, Zhejiang, June 22, 2018] Zhejiang Zhoushan Unicom and Huawei announced the completion of RulalStar on Xiaoqushan Island, Zhoushan 2.0 to provide high-speed mobile Internet services for islanders. RuralStar 2.0 is a low-cost and easy to deploy rural network solution provided by Huawei. RuralStar of Xiaoqushan Island The deployment of 2.0 ended the island's history of no 3G and 4G, reflecting the efforts of Zhoushan Unicom to actively promote universal communication services and accelerate the construction of 4G networks in remote rural areas and islands.
Zhoushan Islands are scattered all over the country, and residents are widely distributed on islands of all sizes. Among them, Xiaoqushan Island, known as "the thoroughfare of the sea", is an important sand and gravel mineral base in Zhoushan, although it is small in area. There are hundreds of quarrymen and their families on the island, who usually live on the island most of the time. Mobile phone signal is very important for daily work and life.
There are many difficulties in establishing wireless base stations on remote islands. The first is the problem of commercial sustainability: the small number of residents on the island leads to low base station income, and the base station cost must be low enough to make both ends meet. The second is the technical problem of transmission: the cost of submarine optical fiber is too high, and it is not economical for relatively small islands. For microwave transmission, LOS and deflection angle tolerance must be small (1~2 degrees), which are greatly affected by rain attenuation, and require high rod height and stability. The overall deployment cost is high 。 Therefore, Xiaoqushan Island can only rely on the nearby large island base stations to provide weak signals.
Zhejiang Zhoushan Unicom actively fulfilled its obligations of universal communication service, narrowed the "digital divide" between urban and rural areas, and with the support of provincial companies 2.0 Base stations are innovatively deployed on islands. The RuralStar 2.0 base station adopts a minimalist design, and its cost is 50% lower than that of traditional tower stations. In terms of transmission, RulalStar The RRN wireless self return scheme used in 2.0 can use the LTE signal of the existing macro station as transmission, and can still be used in the NLOS scenario. The deflection angle tolerance is high (typically 5~10 degrees), the rain attenuation effect is small, and the overall deployment cost is low.
