Aerohive Networks has announced the availability of an online planning tool that can give you an estimate of how many APs are needed in a Wi-Fi deployment using Aerohive or other vendor APs.

According to Aerohive, "This tool can give you an estimate of how many APs are needed in a deployment and where to place them. You can model the physical space that you're in, and see how the Wi-Fi network reacts when you drop in APs. As well as being useful for planning Aerohive deployments, because it estimates the coverage based on the radio type (e.g. 802.11n 3x3 MIMO), it also works for other vendors' products too. Finally, you can print a report of your planned deployment."

This planning tool is a subset of Aerohive's full product, the Online HiveManager.

It's super for proactive planning of your network, especially since it allows for customizing parameters such as the materials in the walls (brick, drywall, etc.).  Of course, you can also import an existing floorplan.

Rather than either using trial and error or going through a repetitive cycle of placing APs and then measuring the signal strength, this is a great tool for knowing what to expect in advance as a part of an existing or new installation.

I've spent some time testing the tool, and it is indeed quite impressive.

You mention that this tool can work with multiple products. Can you explain a bit about how that works?

The planner estimates the coverage based on the radio type (e.g. 802.11n 3x3 MIMO). When you are using the planner you select the AP type, next to the Aerohive AP type (eg HiveAP 320)it also displays the radios used for example Dual 802.11n 3x3. This way you can make an estimate for different vendors APs, not just Aerohive ones

The diagrams are quite impressive in terms of showing coverage. But what do you expect the accuracy to be? In particular, when you've planned with a real environment and then taken measurements of signal strength, what has been your experience?

Like any predictive planner the accuracy will depend on the estimated attenuation characteristics of the walls and other structures that you create versus that of the actual deployment. We are not recommending this as a replacement for site surveys but as a way for you to get started in estimating how many APs you need. This is usually the first and hardest question. Do I need to budget for 3 APs or 15 APs? This helps you get in the right ball park but it still is only an estimate based on a set of assumptions.

The tool is in two diminsions. What are the assumptions that you're making from in terms of multi-story buildings?

Yes the tool is currently 2 dimensional. You can plan multi-story facilities by creating different floors but the coverage provided by the floor above or below will not be taken into account. We expect to have this work 3 dimensionally for multi-story deployments in an upcoming release.

Since the appearance of the tool is currently two-dimensional, why is there an option for setting the height of the access point? For instance, is there an assumption that cubicle walls don't extend to the top of the ceiling?

Ah, I have to admit my previous response was imprecise. While today, it can't factor in the coverage provided by the floor above or below, it does use antenna patterns, AP height, assumed cubicle wall height (6ft) and assumed laptop/desk height to estimate the coverage.

Is this tool a stand-alone product, or part of a wider product line? Either way, what is the model for pricing and do you have any RoI information?

This planner is an integrated part of HiveManager, our Wireless NMS. We leveraged our HiveManager Online (cloud-based management) delivery to also create a separate instance just for the Planner. This allows people only interested in the planner to have free and easy access to it via the web, but without seeing the rest of HiveManager. For people looking to demo the full HiveManager there is also a demo HiveManager Online system (including planner) that allows you to configure and manage simulated APs.

I noticed in the demo that quite a bit of signal spills over into the out of doors. Presuming, for argument's sake, that the enterprise wants to keep coverage indoors, how does Aerohive recommend mitigating the security implications of the signal leakage?

You could limit leakage by positioning the APs and adjusting the power but most Wi-Fi Security experts would say that security based on a weak signal around the perimeter of a facility is a losing proposition. Regardless of how faint the signal is outdoors, an intruder can use a highly-directional antenna to capture it. Strong authentication and encryption, management frame protection and WIPS are the industry recommended ways of providing Wi-Fi Security.

This is a great example of the fine line between "security" and "availability." Since the planning tool has the capability to insert windows on the exterior walls, it seems that one could also predict coverage for outside areas, such as patios and/or walkways between buildings where you might want to extend coverage.
