ExteNet Systems, Inc.

ExteNet solutions allow Wireless Service Providers to tackle even the most complex coverage and capacity issues. Based on a distributed antenna system (DAS) network architecture, our networks give you a powerful way to blanket any area or geography. We make it all work by combining our expertise in network design and construction with scalable, technologically advanced software and components. And that means end users get strong, consistent signals anywhere within range of an ExteNet Open DAS Network.

ExteNet’s Open DAS Network solutions enable Wireless Service Providers to centralize their equipment in a Base Station Hub (BTS Hub); capacity may be augmented or coverage extended by adding remote nodes to the ExteNet fiber backbone.

Network Components

BTS Hub: This is the central location where all Wireless Service Provider equipment is installed. It also houses ExteNet’s optical conversion equipment.

Optical Conversion Equipment (OCE): The OCE converts the radio frequency (RF) signal from the Wireless Service Provider’s BTS equipment to an optical signal, which in turn is routed via fiber optic cable to specific node locations.

Nodes: Once the signal reaches a node, each node then converts the optical signal back to a wireless RF signal. The RF signal is transmitted over a small, unobtrusive antenna that is typically mounted on an existing piece of municipal infrastructure such as a utility pole, light post or bus stop sign. The ExteNet-designed antenna arrays broadcast any combination of standards-based signals from all Wireless Service Providers.

Distributed Antenna System Topography

Network Performance

The DAS network architecture significantly reduces interference across the network. The interference picture improves because the nodes that are transmitting the RF signal from the BTS Hub are typically 30-40 feet from ground level. This low transmitting height provides natural signal isolation and helps reduce interference. Power levels are also significantly reduced, which further minimizes the potential for interference.

With the node close to the user, our networks increase mobile battery life, improve the utilization of spectrum and RF resources and boost data throughput from between 120% to 190%.

ExteNet will install or lease fiber that serves as the backbone for the network. ExteNet will also construct the BTS Hub in an existing building at a Wireless Service Provider macro site or in an outdoor shelter to centrally locate all Wireless Service Provider and ExteNet equipment. Once implemented, the ExteNet Open DAS Network provides support for multiple Wireless Service Providers and technologies.

Future Services and Technologies

The ExteNet Open DAS Network supports a wide range of frequency bands and technologies. New technologies and services such as 3G, UMTS, CDMA-2000, 4G, 802.16 (WiMAX) and 802.11 (WiFi) can be implemented by simply adding the required BTS equipment at the BTS Hub. This provides for immediate provisioning of new services. More importantly, the ExteNet Open DAS Network architecture eliminates the need to retrofit existing sites or add new sites with every new generation of technology.
