Duplex communication interface.
4G LTE are the standards of a global general-use, including two kinds of network modes FDD and TDD, are respectively used to paired spectrum
With non-paired frequency spectrum.Operator's initially choice between two patterns is purely for the consideration to spectrum availability.Fortune mostly
Battalion business will dispose two kinds of networks simultaneously, so as to all frequency spectrum resources for making full use of it to possess.FDD and TDD technically areas
Very little, the main distinction are not that FDD (FDD) and time division duplex (TDD) are two using different duplex modes in fact
The different duplex mode of kind.
FDD is received and transmitted on two symmetrical frequency channels of separation, with protection frequency range come separate receive and
Send channel.FDD must use paired frequency, carry out differentiating uplink and downlink link by frequency, its unidirectional resource is in the time
On be continuous.FDD can make full use of the frequency spectrum of up-downgoing when supporting symmetrical service, but when supporting non-symmetrical service, frequency
Spectrum utilization rate will substantially reduce.
TDD receives and sent channel with the time to separate.In the GSM of TDD modes, receive and transmission makes
By the use of the different time-gap of same frequency carrier wave as the carrying of channel, its unidirectional resource is discontinuous, the time in time
Resource is distributed in the two directions.Some period sends a signal to mobile station by base station, and the time in addition is by moving
Platform sends a signal to base station, must harmonious ability work well between base station and mobile station.
Using the arenas fall arrest alarm platform of the present invention, can not be provided immediately for live performance personnel for prior art
The technical problem that radiating is tactful and field apparatus automatization level is low, is completed to scene by a series of intelligent detection equipments
The detection of various parameters, the control to live various parameters is also completed by the control mode of structural control device, so as to safeguard
While performing environmental degree of comfort, the reliability of platform device is improved.
