Claim 12:
13. An open wire surface wave wireless coverage system, comprising at least one micro base station and a plurality of coupling devices, the micro base station being connected to at least one of the coupling devices through a waveguide,
wherein, each of the plurality of coupling devices comprises:
a high-order mode direct coupling module configured to couple a first electromagnetic wave from a transmitter to form a second electromagnetic wave propagating in a preset high-order guided wave mode;
a mode converting and filtering module configured to convert the second electromagnetic wave into a third electromagnetic wave propagating in a superposition of a plurality of guided wave modes comprising a preset low-order guided wave mode and at least one high-order guided wave mode, and filter the high-order guided wave mode in the third electromagnetic wave to obtain a fourth electromagnetic wave propagating in the preset low-order guided wave mode; and
a mode matching module configured to convert the fourth electromagnetic wave into a fifth electromagnetic wave propagating along a surface of an open wire in a target guided wave mode,

wherein,
the micro base station is configured to send an electromagnetic wave carrying information to the coupling device connected to the micro base station through a waveguide, and obtain an electromagnetic wave carrying information from the coupling device connected to the micro base station; and
the coupling device is configured to couple the electromagnetic wave carrying information sent by the micro base station connected to the coupling device, to the open wire to propagate along a surface of the open wire in a target guided wave mode, and couple the electromagnetic wave carrying information propagating along the surface of the open wire to the micro base station connected to the coupling device.
