The invention relates to the field of
wireless network high-speed switching and
high bandwidth communication under mobile environment, which aims at solving the technical problem of a
system and a method for realizing bandwidth communication between highway vehicles, wherein, the
system comprises base stations distributed and installed along the roadsides of highways and on-board
wireless communication terminals, which all comply with the WLAN
wireless access 802.11a / b / g / p standard, the base stations are connected by optical fibers to form a
local area network, the on-board wireless communication terminal is also provided with the
global positioning system (GPS) function. The on-board wireless communication equipment can synchronously establish radio links with a plurality of roadside base stations so as to realize the
high bandwidth communication, the
transmission rate of which is higher than the previous
transmission rate by a plurality of times. When passing through the covered areas of different base stations at high speed, the vehicle can adopt the self-adaption rate selection and self-adaption flow method to gradually disconnect the links with gradually weak wireless signals, and establish the new links with gradually strong signals in sequence or in a great-leap-
forward mode, thus realizing steady and extremely soft
network switch, and ensuring communication continuity. The method supports the high-speed mobility of the vehicle, the
multimedia broadband service of the mobile equipment and the large-scale network coverage, and realizes the bandwidth communication of highway vehicles.
