Distributed Antenna System (DAS) - In-Building Wireless
A distributed antenna system that is designed by Cell Signal Solutions’ technicians allows for a powerful wireless network and clear cellular reception.
A DAS (distributed antenna system) is a network of spatially separated antennas that receive their waves from one central antenna, providing a wireless network within a geographic area or structure.
With a standard in-building DAS system the cellular source is usually at a higher elevation, and it provides the wireless signal to the building. Signals are transmitted into the building through head-end equipment which converts the RF signals to digital pulse signals. Wireless distribution then disperses the digital signals throughout the building by way of fiber cabling, and are received by remote node locations that convert them back into RF signals and radiate them through multiple, strategically situated antennas for reliable in building wireless coverage.
For larger applications or for stadiums, cellular coverage is usually not an issue. The problem is when you 80,000 fans at a football game the capacity of the macro environment cannot adequately service so many simultaneous connections. A DAS for stadiums are therefor fed through a carrier installed network of base stations. This enables the integrator to sectorize the DAS into many smaller area, enabling many small cells which enhances the capacity and coverage. CSS has found the Mobile Access Fiber DAS platform to be the go to manufacturer for these large in-building DAS networks.
A distributed antenna system supports numerous wireless technologies, as well as a public safety system. It offers the capabilities for each industry’s unique specifications, be it healthcare, hospitality, enterprise, or the like, and access to radio communication for first responders in case of an emergency.
CSS has shined in the Hospitality industry for many years. With multiple contracts with Marriot, Hyatt and other leading Hotel chains CSS has designed custom DAS and repeater solutions. In recent years the growth of DAS in all industries has made in-building cellular as one of the leading verticals in the technology sector.
Recently there has been a lot of talk about the pros and cons of DAS and small cell technologies ie, femto and microcell technologies. At CSS we are technology neutral and will work on the solution that makes the most sense for your customers. There have been many scenarios where CSS have recommended femtocell technology over DAS or cell repeater solutions, it all depends on our customers unique needs.
Reliable wireless distribution is an integral part of business and pleasure, and it is only high quality in-building distributed antenna system that can deliver an optimal wireless network system.
