Innovations in DAS Tags: das and cell phone booster DAS vs Cell phone booster DAS Vs cell phone repeater DAS vs Cellular signal booster

 

DAS technology has been around for more than 20 years. But now, the need to do more with fewer assets is driving innovation in DASs and optical networks. DAS solutions not only address the need for small-cell delivery, they also address efficient small-cell backhaul. Mobile operators are anxious to implement the latest DAS and fiber technologies to create leaner, more cost-effective deployments. 

 

By digitizing the signal on the fiber, the DAS can transport the mobile signal at full strength to any remote antenna connected, no matter how far away it is from the main hub and base station. This is in contrast to older, analog systems that transported RF signals over coaxial cabling and whose performance diminished in proportion to the distance of the remote antenna from the main hub.

DAS And FTTx

To avoid having to build out a whole new fiber network for a DAS, service providers can partner with wireline carriers to piggyback DAS traffic on an existing fiber-to-the-x (FTTx) installation. Wireline carriers can participate in this model most easily by offering “a la carte” services to the wireless service provider that provide access to fiber, offer optical efficiencies, or provide leased physical space for the network infrastructure and gear. 

The fiber in an FTTx network typically originates in a serving office with great access to necessary facilities to host or “hotel” BTS resources. Access to electrical, backhaul, HVAC, and, importantly, fiber to the remote nodes creates an environment where the wireline operator can lease space, eliminating the need for the wireless operator to develop a new site to locate the BTS resources. The wireline operator then has the fiber from this serving office running deep into the network serving its FTTx investment.

To overlay a DAS on an FTTx network, the wireline carrier can:

• Monetize spare or dark fibers that may be available as reserved for spares or expansion of the wireline network

• Use optical splitters that link the wireless signal from the basestation to the FTTx network for distribution to the remote units

• Offer wavelength services where dark fibers are not available

• Speed time-to-market by using existing fiber assets to take advantage of zoning approvals already completed

• Utilize space within a central office, basement, enclosure, or hut to house wireless carrier basestations that will provide the signals for the DAS.

• Utilize common backhaul, power, and HVAC to minimize cost and environmental impact

• Minimize time-to-service with easy-to-zone, non-aesthetically disruptive solutions overlaid on the existing infrastructure and real estate
