Everything You Need To Know About DAS for In-Building 5G
Have you ever been in a building where your phone signal was weak or nonexistent?
Well, you are not alone. Buildings, especially large ones, can often block or weaken cellular signals, making it difficult to make calls, send texts, or access the internet. That’s where Distributed Antenna Systems (DAS) wireless systems can help. DAS is a network of small antennas placed throughout a building to amplify and distribute cellular signals. It can provide seamless coverage throughout the building, even in areas where traditional cell towers can’t reach.
But do you know what exactly DAS is, and how does it pave the way for seamless 5G experiences within buildings?
Hence, to answer your questions related to DAS, our blog will walk you through it.
Understanding the Basics of DAS
DAS is a type of network technology that is used to improve cellular coverage in buildings. It consists of a network of small antennas distributed throughout a building and connected to a central hub. The hub receives the cellular signal from outside the building and amplifies it before distributing it to the antennas. It allows for better signal penetration and coverage throughout the building.
Understanding 5G DAS Signal Sources
DAS systems have two main parts – a signal source and a distribution system. When setting up 5G DAS, building owners need to know about two signal sources – small cells and off-air signals. These sources have their advantages and disadvantages. So, building owners need to talk to DAS experts. Professional experts can help choose the right signal source for the venue based on its connectivity needs and budget.
5G Small Cells – 5G Small Cells, also known as gNodeBs, use special fiber cables or the internet to connect to the service provider’s network.
Off-Air 5G Signal Source – An off-air 5G signal source uses a special antenna placed on a building’s roof to capture signals from the nearest cell tower. However, this system’s performance depends on how good the 5G signal is outside the building.
Is it Necessary to Build Additional DAS Infrastructure for 5G?
Yes, 5G needs a different technology than 4G. Whether a building owner has to change or upgrade their existing system depends on what they already have. They might not need a whole new system if their 4G system can be upgraded and supports new 5G frequencies. Some older systems can be updated through software, but they won’t support all 5G frequencies unless the original equipment was designed for them. However, replacing the system for better performance and cost-effectiveness might be better. Newer 5G systems work much better with certain technology, which older systems usually don’t have.
In The End
In-building distributed antenna systems can be complicated, but building owners can make better decisions if they understand 5G. Knowing more about 5G helps them work with experts who can set up a 5G system by installing a new one or improving an existing one. The right expert will help owners pick the best solution for their building’s needs and ensure the 5G system works as expected.
