Distributed Antenna Systems (DAS)

ExteNet Systems Enables Advanced Mobile Connectivity via Distributed Antenna System (DAS)

Distributed Antenna Systems, or DAS, originated from the need to provide wireless coverage in hard-to-reach areas. These included indoor settings like commercial buildings, convention centers, airports, stadiums & arenas, hotels & train stations, and outdoor settings like suburban and urban locales, canyons, tunnels and highway corridors.

ExteNet’s DAS networks combine a number of small, low power and low elevation antennas & nodes with a fiber-optic network connecting them to a hub facility. DAS networks typically support multiple carriers, multiple technologies and multiple frequencies – thus becoming an integrated carrier-class mobile connectivity offering, with support for 2G, 3G and 4G LTE services and a forward migration path to Voice over LTE (VoLTE), 5G and beyond.

Being a smaller form-factor and less obtrusive, these compact wireless equipment configurations are designed to discreetly blend into the outdoor locales and indoor environments in which they are deployed. ExteNet leaves no stone unturned to ensure the aesthetic value is maintained in every deployment scenario, whether outdoor or indoor.

ExteNet was founded on the premise of delivering distributed networks to improve the connected experience. Over the years, a lot of has changed and evolved - however, a constant has been the meteoric rise of mobile broadband demand and the need for anytime-anywhere connectivity. As capacity and coverage demands increased exponentially and some municipalities passed strict ordinances impacting the construction of macro cellular towers, large-scale outdoor DAS (ODAS) systems were deployed to provide wireless service in these urban and suburban environments. DAS provides the ability to “distribute” wireless services where needed and, as a result, provides robust broadband capacity and excellent coverage.

Outdoor DAS nodes are typically located on existing infrastructure such as utility/telephone poles, street lamps or traffic signal poles which provide a high density of potential sites where these deployments can take place. The ability to place DAS nodes almost anywhere makes these systems ideal to reach areas that are otherwise difficult to serve. Combined with purpose built fiber optic networks, ExteNet‘s outdoor DAS deployments create a strong foundation for future network evolutions.

Today, 80% of all mobile traffic originates indoors but only a small fraction of existing commercial buildings have viable indoor network wireless network solutions. Macro cellular coverage does not suffice in today’s data-intensive world. Indoor DAS (IDAS) installations will transmit signals from the WSPs base station equipment through nodes and antenna locations distributed throughout the facility. Areas that used to be dead coverage spots can benefit from new, reliable and carrier-class mobile connectivity. ExteNet’s relationships with facility owners & managers along with the leading wireless carriers enable these IDAS solutions to be deployed and implemented in a rapid, cost-effective manner, which is mutually beneficial to all parties.

ExteNet’s distinguishes itself with Innovative approaches to solving our customer’s problems. ExteNet can deploy DAS both traditionally and also via the heating, ventilation and air-conditioning (HVAC) system. The latter is a less obtrusive and aesthetically more viable option for indoor mobile and cellular connectivity given the ability to propagate wireless signals from within the building ducts. Referred to as the iDUCT® technology, this method of mobile and cellular connectivity ensures a lower cost of ownership, rapid installation & deployment timeframes, alongside the aforementioned aesthetic benefits. Metal HVAC ducts are typically excellent wave guides for radio signals and the ducts are designed to reach the entire building. Many HVAC systems are designed with a central equipment room and the forward and return air vents are distributed well through a building ensuring ubiquitous wireless coverage for the WSP.

Key Benefits Of ExteNet’s DAS

Multi-carrier, Multi-technology support – a flexible, neutral-host approach ensures cost-effective utilization of resources and infrastructure to deliver network support to all technologies

Broadband Capacity - distributed networks target highly specific user populations, whose capacity can be more closely aligned with requirements, resulting in better utilization of radio resources

Ubiquitous Coverage - traditional cellular infrastructure sometimes does not address hard to reach outdoor locations or logistically difficult indoor venues

Innovative Approach – ExteNet tailors their networks to the unique needs and requirements of each customer - WSPs, venues and enterprises; iDUCT is an example of a cost-effective unique methodology that utilizes the HVAC systems of commercial buildings to propagate wireless signals

Track Record – ExteNet has a highly successful track record of Outdoor and Indoor DAS deployments throughout North America; ExteNet has a vast pool of wireless experts it leverages to design, build and operate some of the most advanced DAS networks in North America today
