The OFDM technology has the advantage of frequency hop spread spectrum, for solving presence of intercell interference, has adopted power control, the power of user's emission energy efficient communication.The OFDM air-link interface adopts Packet Service that the user data rate and the availability of frequency spectrum are improved.Support mobility and based on the business of QoS, and real-time interactive service and being connected end to end, can satisfy the demand of service provider and operator, be easy to deployment and network evolution.
LTE researcher considers to adopt area interference inhibition technology to improve the data transfer rate of cell edge and power system capacity etc.Aspect switching,, also considering between the different frequency and the switching of the lock of different system (as other 3GPP systems, wlan system etc.) except the intrasystem switching of LTE.But the solution of decreased performance is not clear and definite when disturbed by other system to the LTE system at present, is in the process to be formulated and optimized.
