Distributed Antenna Systems

Commercial DAS and RF Engineering

If you’ve ever experienced dropped calls or lack of service inside a building, then you can understand the importance of DAS. Distributed Antenna Systems are intended to extend and enhance wireless communication within structures. We specialize in designing and implementing optimized DAS so your business can benefit from wireless technology. Venue owners, building investors, hotel corporations, and contractors alike want their buildings to support multiple carriers and multiple users throughout or they can face challenges in tenant or client satisfaction. Strong connection signals are only possible with quality RF Engineering. Archis RF engineering services ensure the performance of your wireless networks is always optimized and that you’re meeting all FCC regulations.

As cellular technology changes frequently, so do DAS. Archis follows this growth and applies it to our DAS planning process to ensure your business and wireless users always stay connected whether it’s a new system design or a system expansion. Archis has completed over 250 ODAS projects and over 50 IDAS projects, and 10,000 CW Tests. We work with both new and existing projects to provide flexible and evolving framework for the design and deployment of 4G networks. Archis RF Engineers are not only trusted, knowledgeable team members, but we are also nothing short of:

• Professional and Helpful – you will always feel at ease and in-the-know while working with us
• Highly Trained – our engineers are proficient in indoor wireless design planning and deployment strategies, having performed over 10,000 CW tests to date
• iBwave Certified – a widely recognized software, we are certified engineers levels 1-3 which gives us the expertise to tackle complex wireless projects
• 5G Ready – the platform we employ is currently being tested and used as the 1^stformations of pre-standard 5G wireless networks

Archis DAS Solutions and RF Engineering Services make you and your clients, customers, or patients happy by working flawlessly and quickly. Stay updated in the wireless world we live in!

Emergency Communications Systems

Public Safety Distributed Antenna Systems (DAS) are in-building wireless solutions that allow first responders to effectively communicate during the time of an emergency. Emergency communication is mission-critical to the safety and security of facility employees, guests, and responders in the case of fires, natural disasters, security threats, and more. Without a specific Public Safety DAS, emergency personnel can have a difficult time communicating with each other as dead zones might exist throughout a facility, which makes it a lot harder to efficiently handle an emergency situation. Stairwells, elevators, parking garages, and other common areas where cell reception is often a dud are also common areas where first responders need flawless coverage.

Everyone benefits from having a reliable DAS system, so that’s why the National Fire Protection Association (NFPA) and International Fire Code (IFC) have developed legal regulations for public safety wireless.

Current Public Safety Standards

• NFPA dictates that 99% coverage is required in areas of crucial importance, while 90% is required in all other areas.
• Systems must have monitoring alarms to alert you of power failures and malfunctions.
• The coverage area must have an inbound and outbound signal strength of -95dB or higher.
• Systems must have a battery backup that can run the entire system for at least 24 hours.
• NFPA dictates that antenna isolation requirement needs to be 15dB higher than the gain of the amplifier for your public safety coverage.
• The public safety DAS must be a separate system than commercial DAS.

Planning, Design, and Review

Archis uses industry’s powerful software’s for design services – Atoll and iBwave. Archis provides iBWave Design Level 3 Certified RF Design Engineers to meet client’s design requirements and deadlines. Our team handles design projects for

• Outdoor DAS and Small Cell Network Design
• Cities and Large Venues
• Indoor Stadiums and Malls
• Hotels and Resorts
• Schools

Testing & Data Collection

Data collection is a vital step in the RF design process that provides a solid validation to design objectives. We test facilities with industry calibrated equipment in order to capture and analyze signal strength of your current system. Collecting this data allows us to show you the areas needing optimization and ultimately helps keep costs down. We have performed over 10,000 tests to date for public and private entities. Here at Archis we perform tests, analyze data (if required), and provide a full package of the Drive tests for private and public safety systems, meeting your expectations and deadlines.

• Troubleshooting Drives with Clients
• CW Testing – drive and walk testing
• Baseline Testing – testing the existing network
• Shakedown Drives – handover testing
• Network Pre-Launch Acceptance Drives
