Top DAS Antenna Manufacturers and Suppliers in USA

top das antenna manufacturers and suppliers in usa

Mobile signal coverage and network capacity are major concerns in a building, especially in a shopping mall in a congested urban environment. Due to the natural interferences and high usage of the network, cellular network coverage and capacity provided by cell towers are not sufficient. Therefore, we need to realize systems that can cater to this requirement. This is where Distributed Antenna Systems (DAS) come to play. In this article, we will shortly discuss what DAS is and some of the leading manufacturers in the market who are providing DAS antennas. 

What are DAS antennas? 

DAS antennas stand for Distributed Antenna Systems. These DAS antennas are used by different enterprises to improve the signal quality and strength of cellular connection on a carrier’s licensed frequencies. This system can improve the user experience in buildings in a highly dense urban setting. There are two main components in a DAS system. They are, 

  • A signal source: A DAS system would catch a signal (5G / 4G LTE / 3G) from a source and will feed it into its distributed system. There are three main types of signal sources: off-air (on top of the roof), on-site Base Transceiver Station (BAS) and finally small cells (Femto Cells/ Pico Cells/ Metro Cells) 
  • Distribution system: This system is responsible for distributing the signal acquired throughout the building. There are four main types of distribution systems: active, passive, hybrid and digital. 

Before discussing the different types of DAS antennas, we should clearly identify the objective of installing a DAS system. The two main reasons that drive us to consider a DAS are coverage and capacity. Distinguishing between these two needs is important to get the maximum use of a DAS system. Another critical factor that one would consider is the price of deployment, which can be extremely high during the deployment stage. 

Now let us have a brief understanding about the several types of DAS antennas based on their sub-systems. Off-air signal source systems rely on a donor antenna on the roof to capture a cell tower signal. These are deployed if there are cell towers nearby, otherwise, they are ineffective. This is one of the main disadvantages is such a system. However, it is the lowest-cost option available. In the small cell deployment, a secure tunnel back to the carrier’s network is established via the Internet. This creates a high-quality connection, however, it is expensive. Another option is the use of an on-site BTS. These are installed in the building and a backhaul connection to the carrier’s network is made using fiber optic cables. 

Next, we will investigate some of the signal distribution systems available. A passive distribution system uses leaky feeder cables such as coaxial cables. This will cause the farther ends to receive signals with low strength. On the other hand, active distribution systems use fiber optics or fast ethernet to deliver the signal. Therefore, this system would have equally spread signal levels, and we do not have to bother about the cable length constraints. A hybrid distribution system is a combination of both of these techniques. A digital distribution system uses digital modulation techniques to convert the signal to a digital signal. This makes it less susceptible to noise, however, at the expense of high cost due to the digital conversion of the signal. 

DAS Antenna types

DAS Omni Antennas

An omnidirectional DAS antenna is an antenna that transmits signals in all directions. They are commonly used in indoor DAS systems because they provide uniform coverage. Among them, flat-panel antennas and circular antennas are the more common types of DAS antennas. Flat-panel antennas are usually small, lightweight antennas that can be installed on walls, ceilings, or ceilings. The circular antenna is relatively larger and the effect will be better.

Directional DAS Antennas

Directional DAS antennas are antennas specifically designed to transmit signals in a specific direction. They are commonly used in outdoor DAS systems because they provide stronger signal strength and longer coverage. Common types of directional DAS antennas include parabolic antennas, helical antennas, and rectangular antennas. The main advantage of a directional DAS antenna is that it provides coverage in a specific direction, where the signal will be stronger.

Now having a general understanding of the types and combinations of different DAS antenna systems. Let us find out some of the leading das antenna manufacturers and suppliers in the industry.
