A
distributed antenna system, or DAS, is a network of spatially separated antenna
nodes connected to a common source via a transport medium that provides
wireless service within a geographic area or structure. Antenna elevations of
this system are generally at or below the clutter level, and node installations
are compact, with characteristics of high power utilization, flexible structure
and large system capacity.
DAS
consists of coaxial cables, couplers. Active DAS systems typically employ
optical signal distribution techniques that convert the RF signal of the RBS
into an optical signal by a local interface unit. These optical signals are
then distributed over fiber optic cables to a plurality of remote units, which
in turn convert them back to RF signals. An antenna or coaxial cable small
distribution network is connected to each remote unit to cover each floor.
Distributed antenna systems can be divided into three types: single operator carrier systems, enterprise systems, and neutral host systems. It may be deployed indoors (an iDAS) or outdoors (an oDAS), widely used in commercial, hotel, shopping center, medical, transportation, government, sports venues and other fields, and weak signals such as outdoor deployments, large shopping malls, sports fields, shopping centers, and parking lots.
Currently, due to the increasing popularity of downstream applications such as smartphones and tablets, the global demand for wireless connected networks is growing. In addition, governments are paying more and more attention to the construction of communication infrastructure, the need for DAS deployment is increasing.
One of the core issues of green communication is how to improve the energy efficiency of the system. In recent years, EE has become more and more important due to the deteriorating environment and increasing energy consumption. Distributed antenna systems are gaining more and more attention due to their great advantages in enhancing communication link stability, increasing system capacity and expanding coverage, and become a competition in next-generation wireless communication systems.
Prospect Analysis of Distributed Antenna System Industry in Various Regions
With the continuous updating of products and the development of technology and economy, the market continues to expand. The distributed antenna system is primarily a highly competitive international market. The market is currently at a mature stage, with the high concentrate rate.

Globally, distributed antenna systems are mainly concentrated in developed countries such as North America and Europe, which have high level of economic development, technical and financial advantages and mature markets. However, in recent years, with the rapid economic development and rising living standards in developing countries, the demand for wireless networks has increased dramatically and the market has expanded further.
Distributed Antenna System has a Wide Market, with a Large Demand
Due to the rapid development of the intelligent society, the rapid development of the electronic communication industry, the demand in the downstream market has increased. With the technological innovation of the internet and the internet of things, human demand for data traffic and network service quality for smartphones, tablets, etc. has increased, so DAS will have a wide market. In addition, increase in higher bandwidth applications and in-building demand is also contributing to the growth of the distributed antenna system market around the globe.
According to our research, the global distributed antenna systems is mainly in the development stage from 2013 to 2017. The total market value is 2233.05 million USD in 2017. We predict that the value of the distributed antenna systems market will reach 2872.90 million USD by 2025.
The
manufacture cost of distributed antenna system is mainly affected by five
factors, among which technology, raw materials, equipment, energy and labor
costs account for 21.10%, 40.29%, 5.62%, 12.37% and 18.51% respectively. It can
be seen that raw materials are an important part of distributed antenna systems
and take up most of the cost. In order to maintain a competitive market position,
maximizing profits begins with raw materials. For producers, total production
costs can be controlled through global sourcing, localized procurement, and
centralized purchasing, for large-scale and efficient procurement can
effectively reduce time and labor costs.
With the
development of industries such as heavy industry and service industry, more and
more downstream application companies tend to choose products that can increase
production more efficiently. DAS costs will respond to market demand for high
quality solutions at increasingly lower prices.
For the
distributed antenna system market, most of the customers are large builders,
shopping centers, airports, communications companies and other industries. Manufacturers
should take strategies based on the company marketing positioning. Prices of
DAS depend on what the customer needs and what the customer wants, so they
should pay more attention to these industries, such as their buying habits,
purchase procedures, purchase needs and so on. Except that, the manufacturers
have to pay attention to their supply chain relationship, and offer the best
product and services to their clients.
