Talk:Near-field magnetic induction communication

Two FreeLinc submissions to Wikipedia have been thoroughly edited to eliminate advertising elements. FreeLinc owns the intellectual property which drives the articles and was referenced heavily, including patents, to meet the rigorous source reference requirements of Wikipedia. FreeLinc as the pioneer in Near Magnetic Field Communication Systems, unavoidably, must reference itself. I regret this may seem like self-laudatory advertising, but it is true.

Although compromised, we believe the articles, even post-editing, still have unique and original significance worthy of encyclopedic entry into Wikipedia. We, therefore, respectfully request that Wikipedia publish the entries as edited. The entries, as edited, certainly do not constitute advertising and still convey a novel area of magnetic technology applied to wireless communications.

Thank you for your consideration of this request. Perchwriter (talk) 19:50, 28 October 2008 (UTC)[reply]

A couple of things you need to be aware of: you mention our "rigorous source reference requirements"...these require independent reliable sources...you have provided none. Second, you say "we believe"...who's "we"? I get the strong feeling that you are compromising our conflict of interest guidelines. AKRadecki^Speaketh 22:49, 28 October 2008 (UTC)[reply]

Thank you for your comments. When I use the collective term "we" I am referring to FreeLinc personnel and intellectual property we purchased from Aura Communications in October of 2007.

I appreciate your criticism that the article lacks "independent references." My dilemma is that it is difficult to provide "independent references" because FreeLinc and the assignors of FreeLinc's patents are the pioneers in this field. FreeLinc is start-up company advances a unique technology in a novel manner. I respectfully ask you to look at our website www.freelinc.com and the following link:

http://www2.electronicproducts.com/Nearfield_magnetic_communication_for_low-power_wireless_devices-article-FEBAUR1-FEB2003.aspx

The above linked article, and the references within it, provide authentication for FreeLinc's technology application and the Wikipedia articles previously submitted. This link could be added as a reference. However, I want to point out that the reference might not be considered "independent" because, as stated above, FreeLinc purchased the pertinent Near Field Magnetic Induction chip patents from Aura Communications in 2007 and Aura is cited in the above linked article. The article probably pre-dates FreeLinc's acquisition of Aura's patents.

Aura and FreeLinc implemented this unique application of Near Field Magnetic Induction Communication. FreeLinc won the unique innovative product award at the International Wireless Show in Las Vegas two years ago for our wireless near field magnetic speaker microphone. When a company and it's patent assignor originate the unique application of a technology it is difficult to provide "independent references." And an article referencing yourself tends to make the presentation look like advertising. It is a conundrum I do not know how to solve. However, the concepts and, I respectfully submit, the articles previously submitted, as edited, have intellectual value. Therefore, I hope Wikipedia will honor the articles with publication, as edited, because they provide such novel information. Thank you for your consideration of this request.

The way this is solved is to wait and allow the media to report on your product/service. If it really is notable, industry media will write about it. If time goes by, and no one thinks it's worth covering, then maybe you need to realize that the subject doesn't rise to the level of encyclopedic notability. The main point is, though, that it is inapppropriate for you to be writing about it here. AKRadecki^Speaketh 12:32, 31 October 2008 (UTC)[reply]

unref tag[edit]

I'm tagging this because all the given refs are company docs...this really needs some independent reliable sources. AKRadecki^Speaketh 22:54, 28 October 2008 (UTC)[reply]

News release tag[edit]

I tagged this page as 'news release', as the page contents are copied directly from a FreeLinc document, and all references are to FreeLinc pages or patents. It's an interesting article, but should be rewritten by someone other than the manufacturer, with some non-manufacturer references. w_hairst (unregistered) 13:48, 21 May 2010 (UTC) —Preceding unsigned comment added by 192.58.204.226 (talk)

Given Wikipedia already has Near_Field_Communication I wouldn't have thought it's worth keeping this page. 148.197.66.167 (talk) 11:23, 24 September 2010 (UTC)[reply]

Worst article ever?[edit]

this is quite possibly the worst article on Wikipedia I've seen yet. — Preceding unsigned comment added by 216.36.101.50 (talk) 01:17, 17 January 2014 (UTC)[reply]

Freelinc claims that they developed this technology. This is not true. Magnetic induction was used for hospital paging systems many years ago. From a personal experience, coils were installed in the ceilings and personnel carried simple inductive receivers with an AM detector and an audio amplifier. The system used 20 MHz. I know this because I had 20 MHz ultrasound systems that were interfered with by this paging system.

Inductive communication has been used long before 2008 by the military to program land mines. Smart land mines would be buried and it was desirable to reconfigure them (activate, deactivate, thresholds, etc.) without actually getting too close to the land mine (which was generally seen as a positive benefit by Army personnel).

Pacemakers have used inductive communications starting a few years after their introduction (1980's). All major pacemaker companies, including St. Jude, Boston Scientific, Medtronic, Biotronik, and others use inductive communications to configure the devices and obtain status and diagnostic data.

I think this article could be greatly improved without the need to refer to a specific company's involvement. This is just plain old physics with a history of use dating back to the 50's.

I'll come back later when I have more time and work on cleaning it up with a focus on physics and a number of practical applications.

How can a system = a layer?[edit]

Article says "A Near-Field Magnetic Induction communication system is a short range wireless physical layer". This seems to make no sense. Does the editor really mean "layer"? Please clarify. (PeacePeace (talk) 16:58, 21 February 2018 (UTC))[reply]

Over the air hack via NFMI[edit]

AFAIK is the first hack via NFMI. I was not able to find any other examples in extensive searching, and this attack has the only CVE mentioning NFMI. I'd add it to the article myself, but since it's my work... I assume that is frowned upon, like writing your own biography? So I'll leave some notes and links here instead.

In a nutshell, I was able to crash the DEF CON 27 badges remotely by sending crafted NFMI packets over-the-air and exploiting an off-by-one error, a race condition and a buffer overflow bug. (The first 2 bugs let me build an oversized packet in the badge's receiver buffer, then use that to overflow a buffer.) With a tweak to the badge firmware (to upload a tweak to the NFMI-chip firmware, to remove weird debug code that was mangling received bytes) I was able to demonstrate remote code execution, including writing text like "hello world" to the terminal and playing the Mario Brothers "1-Up" sound on the badge's speaker. I could have controlled the 6 LEDs on the badge as well.
