Distributed antenna systems (DAS) were first deployed about 30 years ago. DAS integration service started out as a solution to provide wireless coverage in areas with low to no coverage, however, with recent advancements in the world of technology, DAS networks today have played important roles in filling the gaps where wireless coverage is weak. The use of DAS networks have also achieved the capacity of traditional networks in high traffic areas.
For a DAS system to function at the best capacity, you’ll need an ideal setting, which can include:
- A large indoor area like high-rise office buildings or airports
- Contiguous outdoor areas such as stadiums or open courtyards
- A combination of suitable outdoor and indoor environments such as college campus.
Operators now install a network of connected DAS nodes that are linked by fiber to a central communications hub instead of building a new tower. The low powered antennas deployed in recent times are the size of fire alarms or smoke detectors and cover a short range which could easily be less than half a mile.
DAS & Joint Assets
Small Cells DAS are mostly installed on existing infrastructures such as streetlights, utility poles and buildings. Poles are however on top of the list because they are versatile, widely installed and allow for fast deployment, readily available and highly stable. The DAS can also be installed alongside other attachments and power thus reducing the need for additional supporting attachments and minimizing the physical and visual impact.
Taking into account the current ratio of DAS deployment, future predictions reveal that at the end of 2018, over sixteen million DAS nodes will have been deployed.
DAS Vs Small Cells
The DAS has been in use for decades, however, small cells are much recent. Both the DAS and small cells share some similarities especially with respect to power output, coverage areas and size. Irrespective of the similarities, both systems boast of some differences.
The DAS are carrier-neutral which means multiple carriers can make use of a single node with the nodes boasting of ability to handle a range of frequencies including 2G, 3G and 4G commercial frequencies, public safety, UHF and VHF bands. The DAS was designed specifically to scale so as to meet the needs of a growing network and are specifically not ideal for low-density applications.
The small cells however are primarily single-carriers which means only one provider can make use of a single node, in addition to this restriction, small cells are designed to be single-frequency technologies although advancements are being made to ensure that they can be deployed for multiple frequencies and carriers. In addition, small cells are designed to deliver coverage and capacity over a small area and are better suited and adapted for single carrier.
DAS System Installation
While the best technological choice varies based on needs and situations, there is the need to understand that both the DAS and small cells can be combined for positive output.
