Distributed Antenna Systems

Overview

Nowadays, multi-operator indoor network solutions are considered to be applied to more and more medium to large-sized venues to support a high volume of mobile subscribers while high-quality indoor network coverage and performance is delivered. Distributed Antenna System (DAS) enables network functions distributed between centralized units for flexibility and scalability, with technology-agnostic low power radios ensuring high performance throughout the venue. Neutral hosts turn to Distributed Antenna Systems (DAS) that evolve from LTE to 5G and provide scalable capacity and coverage solutions for the enterprises. 

 

ComFlex PRO maximizes the use of existing and future IT cabling infrastructure with fully equipped high power and low power systems of turnkey solution, delivering LTE speed necessary in today’s fast-paced world. Its future-proof architecture for 5G with benefits including flexibility, as well as power, cost and rack space saving, makes it the DAS of choice of the carriers and enterprises.
