LTE transmission and coverage system for achieving FTTH based on digital technology

Abstract

The invention relates to an LTE transmission and coverage system for achieving FTTH based on the digital technology. The LTE transmission and coverage system for achieving FTTH based on the digital technology is characterized by comprising near-end equipment and far-end equipment, wherein the near-end equipment comprises a near-end duplexer / time slot switch switchover unit, an LTE near-end down link, an LET near-end up link and a near-end digital signal processing unit, the far-end equipment comprises a far-end digital signal processing unit, an LTE far-end down link, an LTE far-end up link and a far-end duplexer / time slot switch switchover unit, the near-end digital signal processing unit communicates with the far-end digital signal processing unit through optical fibers, the near-end equipment is further connected with an LTE signal source, and the far-end equipment is further connected with a transmit-receive antenna. The LTE transmission and coverage system for achieving FTTH based on the digital technology is stable in performance, high in antijamming performance, high in anti-fading performance, high in safety and far in transmission distance, saving network cost and the like.

Description

technical field [0001] The invention relates to the field of LTE transmission and coverage systems, in particular to an LTE transmission and coverage system based on digital technology to realize FTTH. Background technique [0002] In December 2009, the LTE network officially entered the commercial era. Relevant data shows that in 2010, the number of LTE users in the world was only 142,000. By the end of 2011, the number of LTE users in the world had increased to 9.3 million. By 2012, the number of LTE users in the world was approaching 70 million. Global LTE subscribers are expected to reach 900 million in 2016. China is also in full swing for the deployment of LTE networks. [0003] With the transfer of telecom services from voice-based to data-based, especially with the gradual deployment of LTE and the increase in data users, the dramatic increase in LTE mobile data traffic has directly led to a rapid increase in bandwidth requirements. This demand in turn stimulates t...

Problems solved by technology

Due to the high operating frequency of LTE, short wavelength, poor diffraction ability, and large indoor penetration loss, the traditional 2G network construction method needs to increase the number of outdoor base stations. Even if a large amount of money is invested, it still cannot effectively solve the problem of insufficient indoor signal coverage.
