Wi-Fi Site Surveys

You need a wireless solution that will deliver the coverage your company needs—and that means you need a Wi-Fi site survey. To start optimizing your wireless coverage, it is important to determine the required services that will need to be supported across the wireless network.

Productive Wi-Fi site surveys uncover areas where your coverage, speed, security, and other settings can be improved to increase the quality of your wireless connectivity. Having a productive wireless connection plays a major role in your company’s productivity. Because of the rapid rate that wireless surveys and deployments are advancing, there will always be room for improvement.

For every $10,000 USD worth of salary, disengaged employees account for a $3,400 cost to their employer.

The Different Types of Wi-Fi Site Surveys

Access Point on A Stick (APoS)

The APoS method is the proven way of measuring the signal strength onsite and potential placement of access points in each location.

Passive Survey

Passive Surveys are one of the more common types of surveys performed. It shows where the RF footprint of any and all devices that are broadcasting available signals in your space. It helps you visualize what could and currently is being affected by the surrounding environment.

Predictive Survey

Predictive Surveys can be done as a sight-unseen approach. A detailed picture of the space can be mimicked inside of the chosen vendor’s planning tools with gathered information from the client. From this, a fairly accurate placement map can be generated.

Active Survey

Active Surveys are conducted to get a complete coverage picture of your existing environment. The technician attaches to one of your corporate-owned SSIDs and proceeds with the site survey to create a path document with information. It specifies signal strength, channel interference, signal-to-noise, visible number of access points, channel utilization, speed, coverage area holes, and a basic overall health of your wireless environment.

Three Types of WLAN/Wi-Fi Surveys

Predictive

Performed when:

No Wi-Fi available
Building a new structure
Wireless redesign

Information gathered:

Signal Level
Signal-to-Noise Ratio (SNR)
AP Coverage Areas
Number of APs
Channel Bandwidth-Requirements

Passive

Performed when:

Understand current radio frequency (RF) characteristics of a site
Understand the current environmental conditions

Information gathered:

Signal Level
Signal-to-Noise Ratio (SNR)
AP Coverage Areas
Number of APs
Channel Bandwidth-Requirements

Active

Performed when:

Understand current network and coverage
Troubleshoot Wi-Fi networks
Verify performance post deployment

Information gathered:

Associated AP Requirements
Measure round-trip time, throughput rates, packet loss, and re-transmissions

When should I get a Wi-Fi Site Survey?

If You’re Rolling Out a New Facility

Wi-Fi experts will assess your new physical space to establish the optimized locations for access points (APs) to provide sufficient coverage for your user areas. The surveyor will also plan how to run cables in the most cost-effective manner that suits the architecture of your structure and meets all of your network needs.

If Your Existing Facility Experiences Continue to Lag

Devices are progressively being used to perform more diversified functions in our professional and personal lives – which leads to an increasing demand on your wireless bandwidth. A health check survey like this might also be essential for the more industrial (and architecturally challenging) locations like warehouses. These styles of site surveys help to identify dead zones that prevent your connectivity and optimize your current location and APs.

Post-Installation Wi-Fi Validation Coverage Survey

You’ll first need to ensure that your new wireless system is truly ready to meet all your needs and expectations before your big launch. It’s possible that the first new facility survey might no longer provide the right coverage if details have changed from initial blueprints and early walkthrough to the final building stage. A coverage survey determines two things: 1) If everything is where it should be, and 2) if everything is operating as it should. If this post-installation survey finds gaps, you’ll have recommendations on how to configure and place APs to close those gaps in coverage.

Remote Survey

AirMagney and Ekahau are two Wi-Fi site survey software solutions that provide a simple and time-efficient predictive methodology of mapping your WLAN. Remote surveys are often done in congruence with an on-site survey, as there are some key elements that software can’t consider.

“It’s always nice to get more than what you want AND save money!

“We discussed with our CentricsIT rep exactly what we needed, and they came back to us with more than we initially were looking at buying and saved us over 60%. We were amazed!”– IT Manager, Large Southeast Manufacturing Company

“CentricsIT stood out immediately because of their pricing. They blew the other companies out of the water. Furthermore, their customer service and attention to detail was fantastic. Our rep is available to us 24/7. You could even say that he’s an extension of our IT team.”
