Bluetooth LE v NFC showdown [INFOGRAPHIC]

For many years marketers have known that if they could just get the right offer at the right time in front of their customers they could increase conversion dramatically.

Similarly, businesses understood that fine-grained location could unlock loads of potential to reduce friction (e.g. contactless payments), enhance customer service and make employees more productive.

Within the travel sector, Apple’s (in)famous iTravel patent submission is the most expansive set of collected use cases.

And of course the smartphone was going to be the mechanism to unleash all of this potential.

But GPS isn’t able to provide fine-grained enough location to ensure relevancy and doesn’t work indoors. Wifi triangulation is similarly tricky to get accurate enough.

For many years people thought NFC was the answer (I was not among them) and in fact NFC was prominent in the iTravel patent applications.

While most of the discussion around iTravel revolved around NFC as the driver for all the functionality, we all know that Apple has systematically eschewed NFC maintaining that there may be other technologies which could do the job.

And all the while it has invested in Bluetooth LE, embedding the technology in iPhones, iPads, even Apple TVs for the past three years.

Perhaps Bluetooth LE in the form of Beacons will be what unlocks the potential energy of proximity-based services. We shall see, but there certainly is a lot of buzz around the subject.

In any case, this is a really good infographic comparing Bluetooth LE and NFC and is a good way to quickly get up to speed on the technologies if you aren’t already.

Our Methodology

Anyone can claim they do wireless site surveys, including those that walk around using free utilities that check for basic signal strength, without any training or understanding of how wireless works. That may be fine if you only need basic Internet connectivity, but if your network supports mission-critical applications, you need a professional-grade solution.

Our methodologies are what differentiate us from our competition. We start with the belief that combining the best tools and training with years of experience leads to the best wireless solutions available. Our formula for success includes the following:

Expert Certified Personnel

We start with a commitment to having the best trained personnel possible. We only employ or contract with Certified Wireless Network Professionals (CWNP).

We are proud to be a member of the prestigious CWNE roundtable, an exclusive committee of wireless experts dedicated to developing the highest level and most respect vendor-neutral certification in the wireless industry, as well as writing technical whitepapers.


Predictive Modeling

Predictive models, also known as virtual site surveys allow us to efficiently and accurately identify the number of access points required, as well as their initial placement and configuration. Modeling is ideal for creating "what if" scenarios that show us the effects of changes in real time. Our designs always start with a model which we then validate.


RF Spectrum Analysis

Because wireless networks operate in unlicensed frequencies, potential interference from numerous devices such as microwaves, cordless phones, Bluetooth devices, video cameras, etc. can have a significant negative impact. RF spectrum analyzers are the only devices that can identify physical-layer interference, and no onsite wireless site survey is complete without this service.


Onsite Site Surveys / Validation

When the highest degree of accuracy is required for your mission-critical applications, there is no substitute for a professional-grade manual site survey.

Our surveys start with temporarily mounting the same access points and antennas that will be permanently installed. We then use professional-grade software to test not only for signal strength, but Signal-to-Noise ratio (SNR) to test the signal's viability, interference and data rates. Our thorough approach is the most accurate solution available.


Detailed Deliverables

Our reports spell out the facts, and leave no doubt in the customer's mind as to what the wireless network does or will look like.
