摘　　要：为有效进行700 MHz频段5G网络的规划和部署。本文通过链路预算,计算了700 MHz频段最大允许的路径损耗,再结合传播模型,给出了700 MHz频段的覆盖能力。在密集市区、一般市区、郊区和农村场景下,700 MHz频段的小区覆盖半径分别是447 m、623 m、877 m和2074 m。通过参数法给出了700 MHz频段、2.6 GHz频段和3.5 GHz频段的峰值速率对比。最终证明,700 MHz频段具有覆盖距离远和上行峰值速率较高的优势,是实现5G广覆盖的黄金频段,可以显著提高运营商的竞争能力。The aim of this paper is that effectively guide network planning and deployment of 5G network in 700 MHz band.This paper calculates maximum allowable path loss of 700 MHz band through link budget,and then provides coverage for 700 MHz band based propagation model,the radius of cell coverage is 477 m,623 m,877 m and 2074 m for dense urban,urban,suburban and rural respectively.This paper provides the peak throughout for 700 MHz band,2.6 GHz band and 3.5 MHz band through parameter method.700 MHz band has advantages of far coverage and high uplink peak throughout,so 700 MHz band is gold band for 5G wide widely coverage and signifi cantly increases competitiveness for operator.
