 Hi, let's start with the discussion of RFID technology and many other frequencies and markets that it covers RFID radio frequency identification can cover many frequency bands low frequency HF high frequency or UHF which stands for ultra high frequency So you may see Implementations and with low frequency and the 125 to 148 kilohertz band There's been applications there for animal tracking employee badges in some cases High frequency at 13.56 megahertz This is where you will also find NFC, which is a form of RFID Ultra high frequency at 433 megahertz. This is really an Area where we have powered active tags. So essentially you have a Two radios talking to each other and you can achieve distances much further up to a hundred meters in some cases and then ultra high frequency again, this is a we're rain RFID and we Resides and we're going to be talking about solutions here today And there are also other solutions in the 2.45 Five gigahertz range. So where does ST play in RFID? We play in a couple of areas in the high frequency area with NFC We have both readers and tags and we have other seminars You can attend that detail our solutions there and today we're going to concentrate on rain RFID solutions in the Ultra high frequency band Let's take a look at various wireless technologies that might be used for node tracking or gathering information in the IoT world So on the far right of the chart, we have various radios Bluetooth le Wi-Fi and Zigbee You know relatively mid-range expense on base stations and receivers But these are power devices. So there is not a passive receiver So that puts itself off and at a disadvantage for some markets where RFID technologies like NFC and rain RFID would be deployed NFC although relatively low cost Near field technology has a very short read range In that case rain RFID can read one to often 10 meters or more The cost of the base stations a little bit more, but the passive tag is a much lower cost and can be Deployed for many more tags in the field and often is a better choice for many markets that we'll go into today Let's take a look at rain RFID technology from a global perspective Although the reader design would be basically the same Everywhere What functions it performs like reading and writing from tags and the data that it may gather that stored in those tags It should be noted that this technology is not deployed the same frequency globally But you can use the STRU 3993 In all these different frequency bands around the globe Of course, there would be different certifications with different agencies per country that you designed your reader for Rain RFID readers can come in various forms They can be designed for different markets You could see They can be incorporated with a barcode reader for instance or attached to a mobile computer They can be dedicated devices or as in the lower right hand It could be a module that could be integrated into a more complex system Unlike the previous slide, which was mostly battery powered portable Readers for various markets the rain RFID can be fixed readers with the one to many antennas Which help increase coverage for the areas where they're deployed They might be designed with a power over ethernet Which makes it easier to install in that environment without the need to run electricity to the install point They could be designed for outdoor and rugged use as well Rain RFID is gaining popularity in many different markets and discovering new use cases every day You can see it in factory automation where you can optimize Manufacturing or tracking of components the retail industries had a big explosion of rain RFID deployment Inventory of items automatically with fixed readers is a popular use There's been recent deployments for automatic checkout and tracking of items Authentication and tolls has been a popular use over the years We've seen it in smart homes Transportation and tracking of items and containers and in health care, which will go into a little bit more detail Rain RFID has been deployed in the health care industry in recent years One of the most popular reasons is cost the control of medical cost and tracking of equipment reducing loss in the supply chain Due to tracking of items making sure medicines aren't expired Tracking of patient data making sure it's tested and evaluated officially Another industry that's seen deployment of rain RFID is the airlines For years the airlines have been looking for ways to reduce cost That's incurred due to loss baggage and then the IATA the International Air Transportation Association came up with resolution 753 Which to help force that along they were required to Track luggage at distinct points when the passenger handed over to the airline Loading on to the aircraft Delivering to the transfer area and return to the passenger and this is a case where the low cost of the rain RFID tags and The range that the readers could deploy Provided a perfect solution Let's look a little bit more at a rain RFID system as discussed previously when comparing different technologies the Rain reader emits energy which excites a tag or multiple tags in a field These tags can be used for various different applications for monitoring moisture light or power product exploration dates or Location location of a product the range which can be achieved can depend on the reader It can be dependent on the tag and we'll get into a little bit more detail of various factors The determined range on an upcoming slide the RFID system Encompasses both readers and tags. We've talked a lot about readers a little bit on tags So when we use the word tag, we're actually talking about a tag. I see That is designed with an antenna the antenna is on various different form factors could be paper could be the Clothing label could be as we discussed earlier in the trials for the aviation industry in a rugged tag That could be mounted on luggage They we've seen tags used For experimentation of tracking of small items. Obviously, this would be a small range could be designed into Other form factors that could be used in a more rugged environment So as I mentioned range is something I'm often asked about in a system and Want to direct answer and the answer is well, it depends the range that can be achieved has many factors one is we've talked about the power output of the Reader itself the type of antenna that's used with the reader could be a far field near field antenna It could be a linear polarized antenna with a more focused area Which might have a factor in coverage. It could be a circular polarized antenna So we've developed a tool to help you Figure out your RF coverage in your system where you can plug in the different factors of power And polarization and we're happy to share this with you to help optimize your system Now let's start to get into some of the exciting improvements to the ST RFID ecosystem solutions Let's start with the basic building block, which is the ST 25 R u 39 93 Which is a very flexible IC or system on a chip this suited for various different markets It provides multiple protocol support across the 840 to 960 megahertz UHF band It has support for frequency hopping low-level transmission coding low-level decode data framing and CRC checking and we'll get into a little bit more detail inside The ST 25 R u 39 93 integrated RFID reader is truly a system on a chip Has many features including internal LDOs for supply supply noise suppression It has a partially integrated loop filter can be designed with Different 20 megahertz external reference options for a TXO or low-cost crystal The receiver can be single-ended or differential as a spy interface Has debug pins to monitor receiving transmit communications and has a wide range of supply voltage for various applications Here's the pictorial view of the ST 25 R u 39 93 integrated architecture Highlighted some of the features on the previous slide on this slide. I'd like to point out There's a selectable either a zero DBM output out of the IC or a 20 DBM output There's integrated VCO and phase lock loop the framing Area for protocols and logic an on-board dual 24 byte FIFO direct access to the I and Q signals in the mixer And at ST we work with you we open up these registers and we allow complete access for Custom solutions that you might need to develop as you can see the 39 93 is an impressively integrated RFID reader solution but even with all that integration it performs very well on Power consumption you can see benchmarked against two of our chief competitors on a 3.3 volt 22 milli hundred amp battery for equal comparison how much better The IC performs and is well suited for portable reader design along with the IC a big part of the ecosystem that Brings your solution to market involves the evaluation boards and the enablement part of the enablements for the hardware starts with the software and We provide a pure Middleware software stack written in and CC that's compliant of course with the main UHF standard CPC UHF gen 2v2 ISO 6b the code is now common between Applications on the host and any embedded system. So this allows for easier debug and development and reproduction results This can be defined designed for multiple Systems including Windows could be Linux on a raspberry pi 3b board or it could be in As in the case of our development board on an embedded STM 32 device along with the software enablement we discussed the ST 25 are you 39 93 eval kit is available On board this kit has the STM 32 l 476 as discussed there's options to Have an external PA to have 29 dbm of power out or run off the internal PA for 18 dbm of power out Differential rx inputs are on the board There's the multiple antenna connectors and it is populated with both 20 megahertz tc xo and crystal Now let's get into some of the exciting performance improvements that are enabled by the ecosystem of the IC and the software solutions provided by ST We've made many improvements in our solution provided to improve performance least not of which is adaptive anti-collision algorithm Of course during a demo if you knew with a known population size You could have selected Q in advance for highest throughput, but a real-world environment you might encounter a situation with too many collisions Reducing throughput or too many empty slots, which is gives basically the same result so with previously we had a Static anti-collision algorithm now we have an advanced solution. That's optimized for throughput in In addition to anti-collision improvements other improvements were made also The UART speed was increased from 115 k bits to 3 megabits The firmware now has the ability to send available available data asynchronously This now this has given us the ability to increase the history on tags which allows you to have more inventory statistics tags timestamps and slot analysis counters Was employed with the different tari Gone from 25 Microsecond to 6.25 and so what does this do for you the end result is you want to be able to read tags faster and more Reliable, so with the movement from the 1.56 software to 1.88 or above We can exhibit a single tag reads Up to seven hundred and sixty tags per second and we can read 200 tags in a field In as little as five hundred and eighty five milliseconds So we're very excited to work with you enable your next reader design and Share with you these exciting performance enhancements so feel free to reach out to us and To close this Presentation today. We've prepared a short video that Highlights for you a little bit more detail these performance improvements and Included in that in the reference material will provide a link for this last little section.
