Frequently Asked Questions on Wireless Networking

Wireless Site Surveys and More

What is Point to Point Wireless Networking?

Point to Point Wireless Networking involves connecting or linking the wireless networks, Ethernet bridges, and other types of networks between two buildings with in a 5 miles proximity to each other. Point to Point is is a more cost effective solution than implementing two (or more) separate wireless networks. In addition point to point solutions will provide connectivity between the locations, deliver faster loading times, and are easy to implement. Please read our full article on Point to Point Wireless Networking for more detailed information.

What is Signal to Noise Ratio?

Signal to Noise Ratio describes how much of your intended signal is getting through, compared to how much background noise and interference is being picked up and distorting your message. A low SNR is caused by background radiation, physical interference, and overamplification of the original broadcasting machine. For more information, and to find out what ratio is a good ratio, check out our full article on SNR.

What is a NEMA Enclosure?

NEMA enclosures are the cases that keep your electronics safe. The most basic NEMA enclosures are Type 1 and are the simple, usually plastic cases that we're all familiar with for computers, televisions, and most other kinds of electronics. However, there are many levels of higher types which protect against more extreme conditions. For a more complete description, see our NEMA enclosures resource page.

What Does a Wireless Site Survey Cost?

BCI wireless site surveys have huge value, but we keep our prices economical and competitive so we can give the best deal to you. Many of our expenses are passed along at-cost to you, including most travel-related expenses. To see more details on what we charge, see our resources page on what a wireless site survey costs.

What is an Access Point?

Access points are integral parts of wireless networking. How they fit in with routers, modems, and wireless local area networks is key to providing you with fast and reliable internet. But while most of us are at least vaguely familiar with routers and modems, most of us haven't heard of access points with the same frequency. To learn more, see our resources page- what is an access point?

Why Do I Need A Wireless Site Survey?

Unfortunately for the everyday consumer, setting up a wireless local area network (WLAN) for a business, office, factory, or other large setting is nowhere near as easy as setting up a simple home router. To prevent costly delays and lots of frustrated time and money spent on dead zones and stressful configuration, a wireless site survey and a professional installation will identify the optimal way to provide wireless internet in your structure.

For more information, see our resource page- Do I Need a Wireless Site Survey?

What are common causes of RF interference?

Interference can be caused by many things, and is classified differently depending on if the interfering signal is intentional or unintentional, or if it's a signal at all- it could be things like delay spread, multipath interference, intersymbol interference, or even physical obstructions. Check out our resource article for more information on the common causes of RF interference.

How many devices can share one Wireless Network?

There's no one single answer to this question, which largely depends on the type of hardware and number of access points your WLAN is set up for. In general, a single router is capable of supporting 255 total devices- actually 256, but it uses one slot for itself. This is because it assigns each device an eight-digit binary number, between 00000000 and 11111111, and this is the maximum number of different combinations available to uniquely identify each device.

That being said, this number will increase with the number of access points, and higher-capacity hardware is capable of supporting well over 10,000 unique devices, if your business demands that sort of coverage. In reality, just because a piece of equipment may support 255 devices does not mean that it would be an advisable thing to do. The speed and quality of the network would be reduced so much that it would not be practical to use. Our trained wireless engineers can help you find the solutions to these problems.

What Hardware is Required for a Wireless Network?

You don't need a lot of hardware for a wireless network to succeed. It's more important for the hardware to be configured and aligned properly, and in optimal positions without too much undesired RF redundancy. While these requirements may change based on the details of the specific facility at hand, normal large-scale WLANs require the following pieces of hardware:

  • Wireless Access Points
  • Antennae
  • Wireless Site Survey Documentation
  • An Existing Network


If the BCI engineer requires additional hardware for your project, those details will be included in our report to you.

What does a Wireless Site Survey Service Include?

A standard wireless site survey from BCI begins with a highly trained and professional wireless engineer coming directly to your facility. He or she will have the unique tools (including precision RF analyzers) and expertise needed to efficiently cover your entire site, and generate detailed RF survey report in the process. This is a comprehensive report that provides information which may include:

  • A detailed preliminary system overview
  • Existing system equipment
  • Recommended system equipment
  • Cabling information
  • CAD drawings and/or blueprints
  • Coverage patterns
  • Optimal number and placement of access points
  • Specifications for wireless hardware configurations
  • Antenna placement guidance
  • 802.11a/b/g/n RF Network Design
  • Any other details relevant to keeping you in wireless coverage.
