Abstract

The invention, which belongs to the wireless communication technology field, discloses a method for improving a covering range of a field intensity of a wireless communication network. According to the method, an internal diameter function and an external diameter function of an electromagnetic shade are constructed according to a shape of an obstacle; when first order derivatives of the internal diameter function and the external diameter function are discontinuous, the internal diameter function and the external diameter function are fitted into a first and a second substitution functions by utilizing a fourier least-square-fitting method, wherein first order derivatives of the first and the second substitution functions are continuous; and a dielectric constant of the electromagnetic shade is calculated by utilizing the internal diameter function and the first substitution function as well as the external diameter function and the second substitution function; the electromagnetic shade is manufactured according to the internal diameter function, the external diameter function and the dielectric constant of the electromagnetic shade so as to cover the obstacle. According to the invention, a covering range of a wireless field intensity is effectively improved and shadow fading is eliminated.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for improving the field intensity coverage of a wireless communication network. Background technique

[0002] In the mobile wireless communication system, the electromagnetic wave emitted by the transmitter often has no direct path between it and the receiver due to the obstruction of the obstruction, so that the received signal strength decreases and the communication quality is difficult to control. Therefore, studying the method of increasing the field strength of the shaded area, that is, the shadow area and the weak field area, is beneficial to increase the field strength and coverage strength, extend the communication distance, and improve the communication quality.

[0003] For the edge of the cell or the weak field area, it is usually compensated by adding a micro-cell structure, a relay node, or adjusting transmitter parameters. The c...
