But the long term of monitoring request that the
achievement of equipments is to consume low and can save
a great deal of environment data. To solve these problems,
we use ready-made public wireless network-4G network as
the letter way that the data transmission and use low-power
embedded devices as the control center of data transmission,
the environmental monitoring data will be sent to the data
receiving terminal by 4G service. This article is based on a
microprocessor-based ARM 2440, AT command control
4G modules to dial to build 4G wireless network, realizing the remote transmission of environmental data.
