RFID antenna mounts for Laird Times-7 & MTI panels. How to choose? Weight limitations on Arcadian's EZ brackets

Posted on Wednesday, March 18th, 2015

This question has come up several times, and I would like to address it in detail.  See my notes below on each of the EZ mounts and what their maximum weight loads are.  Keep in mind that there are TWO ratings for each mount.

EZ-M6-COMBO - ARCADIAN INC.

A “static” rating, for antennas that will be mounted in a secure location and not be subjected to any vibration at all.

A “subject to vibration” rating, for antennas that will be mounted in a location that is subject to ANY shake or vibration.  That could be the obvious, like on a vehicle, or the less obvious, like next to a stamping machine, or next to a loading dock.

Here is my input:

We are no longer recommending the EZP4 in 2015.  With the popularity of the EZM6 (6 inch die cast aluminum RFID antenna mounting bracket) most customers are leaning towards spending a few extra dollars for this model, and we are spending more and more of our inventory dollars on stocking the EZM6 (wall, mast & combo)

Notes:

EZP4: 2 lbs. (static install) or 1 lb. (if subject to vibration)  Suitable for:

·        Laird 10x10” antennas in a static environment, but we are no longer recommending this in 2015)

EZM6: 5 lbs. (static install) or 2 lbs. (if subject to vibration)  Suitable for:

·        Laird 10x10” models (S9028PC, PAL902909, PAR90209)

·        MTI 12x12” models (MT-262006)

·        Times-7 smaller models (A6031, A6032)

EZM9: 10 lbs. (static install) or 5 lbs. (if subject to vibration)  Suitable for:

·        Laird 10x10” models (S9028PC, PAL902909, PAR90209)

·        Laird 10x20” model (PRL90209)

·        MTI 12x12” models (MT-262006)

·        Times-7 smaller models (A6031, A6032)

·        Times-7 larger models (A6034 & A6034S) *with or without the sheet metal mounting plate* 

If you are using the EZ mounts in conjuction with Times 7 antenna #'s, A6031, A6032, A6034 or A6034S, you will also require a Times 7 mounting plates.

Maximum load for A5530 / RTAS RFID race timing - chip timing ground mat antenna is No Problem!

Posted on Saturday, March 14th, 2015

We at Arcadian Inc. are in the business of selling RFID antennas, and over the years we have sold MANY of the Times-7 A5530 rugged RFID mat antennas, and it's sister - the Race Timing Antenna System (RTAS).  This model is a high-gain (10 dBiL) linearly polarized RFID antenna embedded in a blue, molded polyurethne "mat."  It has come to be the preferred choice of RFID antenna for our clients building chip timing, or RFID race timing systems. 

Why?  Becuase it is simply the fastest and easiest to deploy on race day.  In addition, we also have many clients who use these mats in conjuction with RFID systems used to track event or trade show attendees.  Well known to be extremely durable, with customer deployments growing rapidly since its debut in 2007, the Times-7’s A5530 / RTAS is a proven endurance performer. 

However, we have had MANY clients ask us..."can this antenna survive foot traffic, bike traffic, car traffic?  What about fire trucks, ambulances and 18 wheel tractor-trailor trucks running over the antennas?"

Well, until this year, Times-7 hadn’t attempted to measure and document the weight bearing characteristics of this RFID mat antenna.  So, recently they set out to do exactly that using an external specialist with equipment to validate what customers were already telling us...namely that this antenna can survive just about anything!

Working with a techinical university in their home country of New Zealand, the research team used a hydraulic press to emulate vehicle load.  The Times-7 ultra-low profile ground mat RFID antenna was compressed with a 10,000 lb. point load. The A5530 / RTAS mat withstood more than 600psi. By contrast, the maximum contact surface pressure of a 42,000 lb tandem axle garbage truck is 215psi.

In conclusion, I am happy to report that we can now say with confidence that the weight bearing properties for the A5530 / RTAS RFID ground mat antenna are in excess of any typical heavy commercial vehicle.

For information on using this antenna for your RFID race timing, or chip timing system, or in your trade show or event tracking system, please contact me or a member of the Arcadian Inc. team for assistance.  We are the antenna experts, and we are happy to help!

How to choose a mobile 3G/4G cellular multi-band antenna for in-vehicle applications (taxi, utility, etc)

Posted on Saturday, March 14th, 2015

Arcadian Inc. is the single largest suppier of vehicular multi-band antenns for taxi cabs in North America.  We have spent countless hours with our clients researching the best antennas for their in-taxi systems used for GPS tracking, infotainment & mobile credit card processing.  If you have an application where you are using in-vehicle 3G/4G cellular modems (like Sierra Wireless GX440 or Cradlepoint, contact me for antenna suggestions.)  

Recently, I was working with a potential client who was utilizing the Wilson 301106 antenna, which is now obsolete.  Of course, I was working to move them over to one of our antennas, and the client's argument was that the Wilson antenna was significantly cheaper thatn anything we could offer.  So I probed further, and asked "how is that antenna actually working out for you?"  The response was NOT so postive.  Apparently, this company was having ALOT of issues in the field with taxi cab drivers struggling to get a cellular connection, and thus being unable to process credit cards in a timely fashion.  

So, I sat down and spent some time digging into their situation, and theorized that the main problem was that they were operating their taxi cab fleet in a part of the city that was particularly densly packedwith tall buildings, thus creating so-called "urban canyons."  

In the end the antennas that I ended up recommending are LOWER gain than the Wilson antenna, (but much higher “efficiency”) and here is why that is a GOOD THING for people facing a similar technical dilemma, and suffering with issue of lack of 3G/4G cellular connectivity to their vehicular modems.  The issues may very well be the choice of antenna.  You see, most people that are not antenna "experts"  do a bit of research, and find that antenna "Gain" is the measurement of an antennas strength, or at least that is how most people understand it.  That leads them to belive that more gain is better, and is the cure all for any cellular connectivity problems.  Gain is typically measured in dBi or "decibals beyond the isotrope."  To over-simplify it, the highter the dBi, the farther the antenna's wireless signal will travel.  0 dBi gain is also known as "unity gain"  More on this below...

Unity gain or zero gain has a perfectly spherical shape, it transmits up, down, and sideways with equal power.  The antennas that I ultimately recommended for this applications are LOW GAIN for urban environments – why?  Because most of the Verizon, AT&T, and Sprint/T-Mobile 3G/4G cellular signals are coming from antennas mounted on towers or from the top of buildings, and you want an antenna that can not only reach “outward” but more importantly, reach “upward.”  The trade-off of designing the antenna in this way is that it has less “reach” from side to side.  However, in these metropolitan cities or "urban canyons" where there are huge buildings on every side, that gain basically goes to waste, as it simply bounces off the buildings and never makes a connection to the Verizon, AT&T or Sprint/T-Mobile antennas that are up on top of the buildings.

The previously mentioned Wilson antenna was designed for rural environments, where the cellular signal is typically far away, (but there are no large buildings providing interference) so what they do is they “compress” the middle of the signal of the antenna so that more energy reaches “outward” vs. “upward” 

So, in actuality, in an urban environment, you want to minimize the gain (sideways power) and by keeping the gain low, you maximize the upward reach of the antenna, which is what you want.  Take a look at the graph below.

Arcadian to begin phasing out EZ-P4 RFID antenna mount. EZ-M6 to be the planned replacement.

Posted on Wednesday, March 11th, 2015

Just a quick note to all of our RFID antenna clients...

For many years, we have been providing our "EZ" mounting solutions / RFID antenna brackets.  The have clearly become the RFID antenna mount of choice for OEM's and System Integrators using RFMAX and Laird / Cushcraft.  (These typically mate with 10x10" RFID panel antenna model #'s S9028PCL, S9028PCR, PAL90209 & PAR90209)

Recently, some shortcomings in the EZ-P4 model have come to our attention, and had us re-evaluate this mount.  In light of what we discovered in our own testing, we hvae chosen to phase out this RFID mounting solution.

We will no longer be bringing any additional EZ-P4 mounts into our stock.

Here is our current inventory situation, as of today (March 11, 2015) **ONLY 84 UNITS of EZ-P4 AVAILABLE FOR SALE**

The replacements / upgrades to the EZ-P4 series are our EZ-M6 mounts:

EZ-M6-COMBO - ARCADIAN INC.

EZ-M6-WALL: 6" wall mount

EZ-M6-MAST: 6" mast mount

EZ-M6-Combo: 6" wall and/or mast mount

Why the move? 

1.      The EZP4 is too short to fully articulate the antenna.

2.      Although it can hold the weight of one antenna,  it may be unable to handle the weight of antenna + a cable (depending on the cable type and length)

3.      The EZM6 is a more robust solution, that allows full articulation of the antenna, and can hold 2x the weight of the EZP4.

If you have any questions about this announcement, please contact your account manager directly, or email me at mikec@arcadianinc.com
