Most Common Questions when looking to purchase a DAS or BDA
*Please give me a call or email with any questions you may have. We can help with all aspects of DAS, BDA and Signal Boosters from equipment to licensing . Mark Perretti 919-810-0667 firstname.lastname@example.org
1)Question: What is the first Step once we realize our building or Campus has a cellular or public safety coverage concern?
Answer: We will need to assess the coverage in your facilities. This is done by providing a benchmarking study. We do this with computer software integrated with carrier devices . This will provide measurable results of all wireless operators and 800mhz Public Safety in your buildings. Once the study is complete, it will assist us in generating a system design and equipment list .
2)Questions: What information is needed for Benchmarking studies?
Answer: To provide you with an accurate study we will need Blue prints of the floor plans. PDF or CAD files are fine. Evacuation plans are acceptable, but often don't provide the detail that you as the customer would like to see. And obviously an address and contact information will be needed.
3)Question: Is there a cost associated with Benchmarking?
Answer: Yes, a small cost is associated with these studies. The key is it's providing information that could save you money as well. For example their may be entire floors that don't need the BDA or DAS because the study has determined that adequate coverage already exists.
4) Question: What is the next step after benchmarking and site assessment?
Answer: A detailed Site survey of the venue to determine equipment placement, parts list and equipment specifications. Development of a complete "Scope of work", that includes Public safety bands, carrier operators that the DAS needs to support. In addition detailed design drawings showing equipment locations and cabling paths overlaid on the floor plans are provided.
5) Question: Once approved, How long does the installation take?
Answer: It really does vary depending on size and scope of the project. A typical project is about two-three month process from benchmarking, design walks, design plans, a complete scope of work, ordering equipment and the actual installation, commissioning and going live. All projects includes project managers with a complete schedule.
6) Question: Will my cellular carrier provide financial help for my DAS or BDA Project?
Answer: We get this question most often. The answer is mixed and It really depends on a couple of variables. First let me comment that most budgets have typically been forecasted from previous years. This means you really need to be a big "Blue Chip" account with long standing relationship and a good amount of lines (cell phones) with the carrier to potentially get some funding. Verizon seems to be the most friendly, with AT&T running in second and all other carriers are a distant third place. If your a large enough account and fortunate enough to get funding it typically will only fund their portion of the DAS. Also almost always your going to need to fund the Public Safety piece.
7)Question: Our City, County or State owns a Motorola P25 800mhz Public Safety System and would like conduct our own in building coverage assessment, Can this save us money on Benchmarking.
Answer: Yes.....You can test push to talk (PTT) voice, plus most Motorola radios have a feature to display the RSSI (received signal strength indicator). You can provide us the areas of the buildings you feel would not need benchmarking studies. Just realize that our system design will not include areas you have designated as public safety covered.
8) Question: How much is the system going to cost?
Answer: The primary drivers of cost are the size of buildings or campus and the number of carriers built into the DAS. Plus, mission critical public safety is another variable in cost if added.
9) Question: Is my DAS future proof for LTE and other carrier services?
Answer: Yes this is a common question about the DAS system Topology. consideration of future expansion of carrier services to the existing architecture is a common practice.
10) Question: I'm an Engineering/Architect Firm or Electrical contractor working on bid response for a BDA or DAS. Would you be able to provide an estimate for a system?
Answer: Yes, with some basic information on the square footage of the buildings and the wireless operators they are looking to include. We can provide very high level estimates.
Question: Do any agreements need to consummated between wireless operators and the end user?
Answer: Yes the FCC mandates that any re-broadcasting of the carriers radio signal will require an agreement between the operators and the DAS owner. We have a clear understanding of this and will guide you through the process.
Question: We have our own cable pullers or contractor for pulling line, can they be used on this project?
Answer: Yes....On many occasions we have been asked this question, in particular with new buildings, plants or renovations that are taking place. Existing contractors are very familiar with customer preferences. One of our engineers will review the DAS or BDA design and cable paths with the contractor or individual for clear demarcation of the scope of work. One note, that this should be brought out in the initial assessment and design walk stage. the earlier the better....
Question: Are their any specific Fire codes that require DAS or BDA systems for Public Safety in new or renovated buildings?
Answer: yes....Public Safety Radio coverage, The IFC 510.1 and NFPA 72 Ch. 24 now has code that supports a requirement for in building 2-Way Radio coverage for Public Safety Communications that is being adapted.
Question: We have an existing BDA and want to add a DAS for additional cellular and Data coverage. Could the new DAS interfere with the BDA ?
Answer: Yes...It's very important that our engineers look at the existing BDA system to determine the new DAS system antenna placement. Or the potential for interference could occur.
Please give us a call with any questions you may have in regards to DAS and BDA, we would be delighted to chat with you.
