Key technologies and innovations RRU
A Remote Radio Unit (RRU) is a wireless base station.
The main subsystem in the system basically completes the basic one
Processing of the transmitted signal and reception of the signal brought to the radio interface
Processing, the main functions are shown in Figure 1.
The RRU system consists of a transceiver (TRX), a functional
amplifier, a filter, an antenna, a power supply and
a subsystem structure of components, including TRX, a power amplifier, a radio frequency
Algorithm, filter, antenna Five proprietary key technologies
technical direction.
RRU serviced by key RRU technologies are located in
In each subsystem of a wireless network there are two first elements: the main
Shipments of equipment came in first place (account >70%);
Sales take the first place (>45%). Because of the wireless network
Network – the share of sales in the operator's network
The highest part, so it can also be said that the RRU is in
The share of sales in each subsystem of the operator's network
The first.
Based on the position of the RRU, the four main communication
Equipment manufacturers have invested a lot of effort and materials
to increase the key competitiveness of RRU products,
Get the appropriate market yield for the period.
Key Competitiveness of RRU products (Strong Business Efficiency
Power, high efficiency, low cost, small size, light weight
, etc.), one of the main points is to do a good job of disabling the RRU
development of key technologies. ZTE is well aware of this.
that's why there are a lot of constant investments in this direction
in human and material resources. Through decades of continuous research
According to the study, ZTE has already developed a key RRU technology.
From follower to industry leader.
In this article we will talk in detail about the introduction of almost ten years
The division and direction of development of the key technological direction of RRU in the future
is momentum and innovation.
