DAS, C-RAN, Small Cells, Femtocells, Everyone Is looking for Spectrum Space


Everybody loves their cell phones, but increased cell phone and data usage has become a challenge for wireless service providers.  Ever increasing data speed and coverage demands require the wireless industry to grow at an explosive rate and hamper its ability to keep up with the need for new cellular towers.  To support this overwhelming demand, carriers are using Distributed Antenna System (DAS) Networks, macrocells, microcells, picocells, and heterogenous networks (HetNet).  The wireless industry is quickly incorporating all of these technologies to help keep up with data usage, and each system must have a GPS signal for timing and synchronization.

DAS refers to a network of antennas that enhances the range and capacity of cellular networks inside large facilities such as public venues (stadiums, malls, convention centers, etc.), hospitals, hotels, resorts, office buildings, universities, and manufacturing facilities. It also provides coverage outdoors, where network connectivity is low or traditional cell towers cannot provide it, such as roadways, parks, and oil refineries, among other under-served areas. DAS platforms redistribute the signal from a central location and do not have baseband technology integrated. They are being designed to support all mobile operators and all bands in a single system.

Whether small cell or DAS, a system needs to be engineered so that it can be monitored, and when necessary, have redundancy. Therefore, when designing our new product line for DAS, GPS Source took into consideration the need to ensure the proper end user experience for our customers.  We looked for the best fit to fill our customers’ small cell, in-building, or distributed antenna systems needs.

At GPS Source, we know that carriers are looking to increase their capacity and lower their costs, while still improving reliability.  That is why our new wireless products have built-in redundancy features and are available at a lower cost than our standard product line.  We accomplished this feat by simply removing features consumers were not looking for and retaining the features they absolutely need. As a result, GPS Source offers top quality products at a competitive price with very short lead-times.

GPS Source offers products to support DAS networks and many other cell systems that support increased wireless data usage.  Our products include high quality GPS splitters for base transceiver stations and BTS Hotels.  They are tuned for GPS, which means they are tuned between 1 and 2 GHZ--not tuned for broadband.  We have multiple power options, such as AC and a variety of DC options, including 48 volt.  There is very little difference between each tested output: each one is +/-1dB from the other. High isolation between output ports is standard.  All of these qualities make GPS Source splitters the best choice for consistent and reliable output of the GPS signal for timing and synchronization.
