Every DAS has two key elements – a signal source and a distribution system. There are three kinds of signal sources that receive cellular signals from mobile carriers, and they are (1) off-air antennas, (2) on-site base transceiver stations (BTS), and (3) small cells. Once the signal is secured from the carrier, it is distributed throughout the environment via different types of solutions, notably active, passive, small cell, or picocell distribution systems.
The choice of distribution system is driven by a number of factors:
- How big is the coverage area?
- How many devices and users are expected to utilize the enhanced cellular network (commonly referred to as density)?
- What mobile carriers do you need (Verizon, T-Mobile, AT&T, US Cellular, Dish, regional carriers)?
- What is the performance goal of the enhanced network? Does the DAS need to solve for issues like capacity, frequently dropped calls, and/or speed and latency issues?
Pierson Wireless can guide you through an analysis of these factors to determine which distribution system best fits your use case.
