Innovations in Tracking High Value Assets

Today's high value assets can be tracked by delivery on-line in transit; but once it gets to it's destination the responsibility ends there

Inventory sometimes is lost upon receipt at the destination

Integra Systems, Inc. has developed a ecosystems IoT offering to track assets effectively at a very competitive price point. It is the first tracker of it's kind with NB-IoT, LTE-M, and GPS that has an extensive battery life.

Additionally this solution includes BLE (Bluetooth Low Energy), a motion accelerometer together with a temperature sensor; and to include a unique activated service button.

Finally, this is globally carrier qualified and built to industrial hardware requirements. The SIM is activated on the appropriate network, product is kitted, then shipped. Zero IT requirements from the user.

In other words, ready to go out of the box upon receipt to provide immediate business value.

The return on investment of this architected end to end solution is:

- Reducing potential theft and to allow the user to be in control of the knowledge and location awareness of any high value asset real time on a global basis
- Ensure temperature control on critical assets
- Detect movement to deter theft and validate the shipment
- Validate and verify potential shock to the shipment

All of this is accomplished through a managed portal that the customer has access to combined with customized geofencing and algorithms tailored to the user.

RTLS or now location tracking for 2020 - Integra Systems, Inc. offerings

Integra Systems, Inc. has been in around the RTLS space since 1999 and we have seen a lot of changes.

For the sake of now 2020, we will drop the nomenclature of RTLS because we consider this legacy. New business models have come onto the scene based upon the advancement in technology offerings. For example BLE with now 5.1 provides location accuracy never before obtained. Now there is also the release of BLE 5.2.

What are the challenges of asset tracking?

• There is no real time way of tracking high value assets during shipment
• How do you know where your actual asset is throughout the supply chain?
• How do you avoid theft?
• Movement cannot be monitored
• Often there is a need for high cost proprietary infrastructure.
• Temperature sensitive assets cannot be monitored.

BLE is now in every smart phone yet alone being incorporated into the leaders of the WLAN enterprise infrastructure thus we have an indoor solution that takes advantage of the technology changes.

As a result of all this is when standards prevail, costs drop, and then wide spread adoption comes.

Now the location tracking space with NB-IoT and LTE-M, location tracking has moved beyond walls of a building that literally can be anywhere on a global basis.

Integra Systems, Inc has the capabilities through our business partners to provide real business value add solutions for asset tracking throughout the enterprise space.

Our partner ecosystem is globally qualified, and has a strong market presence of 1,500,000 IoT kits deployed with over 50,000 unique configurations.

The solution described is a logistics tracking solution that is based upon cellular 4G which also supports BLE and Wi-Fi.

Positioning is provided by using Global Navigation Satellite System with the ability to provide measurement frequency for positioning and sensor data that can be viewed and changed at any point.

This architecture provides the basics of Geo Location, Interval, Temperature Alarm, and Shock detection alarm. This additionally includes a IoT platform for Alarm panel geo fencing, input of additional sensor data, as well as routing and sensor historical data.

All of this can be tied into a cloud solution via a API or web user client, with direct ERP integration.

IOT LTE-M and NB-IoT for application development

LTE-M

LTE-M (or eMTC or CatM1) is designed for low power applications requiring medium throughput. It has a narrower bandwidth of 1.4 MHz compared to 20 MHz for regular LTE, giving longer range, but less throughput. The throughput is 375 kbps downlink and 300 kbps uplink, providing 100 kbps application throughput running IP. It is suitable for TCP/TLS end-to-end secure connections. Mobility is fully supported, using the same cell handover features as in regular LTE. It is currently possible to roam with LTE-M, meaning it is suitable for applications that will roam across multiple regions. The latency is in the millisecond range offering real time communication for time critical applications. LTE-M is perfect for medium throughput applications requiring low power, low latency and/or mobility like asset tracking, wearables, medical, POS and home security applications.

NB-IoT

NB-IoT (also known as Cat-NB1) is a narrowband technology standard that does not use a traditional LTE physical layer, but is designed to operate in or around the LTE bands and co-exist with other LTE devices. It has a bandwidth of 200 kHz, giving it longer range and low throughput compared to LTE-M and LTE. The throughput is 60 kpps downlink and 30 kbps uplink. It is suitable for static, low power applications requiring low throughput. NB-Iot is perfect for static, low throughput applications requiring low power and long range, like smart metering, smart agriculture and smart city applications.

Enterprise Location Knowledge for 2020

Integra Systems, Inc. has been in and around the "Location Knowledge" space since 1999.

New models have now come onto the scene based upon the advancements in technology offerings in the business location tracking area. It is not about the technology in our opinion; but about the economic and process improvements by the use of the technology that can become realized.

For example; BLE with now 5.1 provides location accuracy never before obtained that will allow visibility of the client to change the game. This field location awareness will allow for potential new work flow and business improvements. See now also the release of BLE 5.2.

BLE is now in every smart phone; yet alone being incorporated into the WLAN AP enterprise infrastructure. This is a true convergence of use.

The bottom line is when standards prevail, costs drop, and adoption comes. Wi-Fi, BLE, and now the converged location knowledge space will provide major business value.

Now with NB-IoT and LTE-M, location tracking can also be provided inside and outside the walls of the enterprise taking advantage of 4G moving to 5G. A true location real time tracking ecosystem has now evolved for 2020 and beyond. When you now have the ability to have the data and mine this on real time basis, huge value is experienced to improve the overall business process.

IOT Location Tracking 2019 moving to 2020

A lot has changed in the location tracking space in the past twenty years.

It is 2019 now turning to 2020 and the technology landscape is now following industry standards.

Standards will drive down costs.

Just look at how Wi-Fi emerged from 802.11 DS and FH prior to 1999, then with the release of 802.11b in 1999, finally with the Wi-Fi Alliance being formed in 2000.

The rest is history.

What has changed?

BLE is now a part of the overall WLAN enterprise. BLE is now being built into the WLAN AP. As a result, location based data now can be provided on a real time basis to a cloud based business model.

Smartphones that incorporate BLE and with BLE based tags now can leverage the existing WLAN infrastructure as the backhaul. This will improve the ROI. Look to BLE 5.1 being part of every smart phone going forward.

Bluetooth 5.1

Advances have been made to provide very precise location accuracy.

Bluetooth direction finding is the major feature of the Bluetooth 5.1 Core Specification. It is designed to enhance location services where previously only signal strength based technology has been used with Received Signal Strength Indication (RSSI).

Bluetooth direction finding will offer new and improved use cases for Real Time Location Systems (RTLS) for asset tracking in a wide range of scenarios from logistics and warehousing to value asset security in healthcare. It also brings added user experiences in proximity-based scenarios for enterprise awareness and contextual information for enabling new business process improvements.

Bluetooth direction finding can be used to detect location in either 2D or 3D dependent on the complexity of its implementation.

Angle of Arrival (AoA) and Angle of Departure (AoD)
Bluetooth direction finding is based around the two key concepts of Angle of Arrival (AoA) and Angle of Departure (AoD). This makes use of the angular phase-shifts that occur between antennas as they receive (AoA) or transmit (AoD) RF signals.

With the use of antenna arrays at either side of the communication link phase shift data can be determined and from this, location can be calculated.

Which approach to choose?

Whether AoA or AoD is chosen for use depends much on the use case, both can be used effectively, but in certain circumstances one or the other will be more suitable given a range of considerations

AoA allows for use of very simple, low cost tags to act as the source device of which can be used to determine the location of the asset. This system would have more complex locator units mounted in an unobstructed manner in location to determine and calculate the position of items that are tagged.

Such scenarios might include:
• Asset tracking in warehouses
• Value asset tracking in hospitals; government, establishments etc.
• Identification of the location of people and staff

AoD requires more complex tags than AoA from a hardware and software perspective. In this scenario the locator device can be simpler in terms of hardware design but does have software complexity for the determination and calculation of the direction finding functionality.

AoD based direction finding has some strong use cases that include smartphones and wearables. At this time smartphones do not support Bluetooth 5.1 but it is expected they will at some point.

Such scenarios might include:
• Wayfinding in large spaces such as airports, hospitals etc.
• Point of interest assistance in shopping malls, exhibitions etc.
• Search and finding of items such as keys, remote controls etc.

Using 4G (Silicon on the Chip), SOC, drives down costs at the edge level.
When the WLAN may not be present, low cost 4G tags can provide location accuracy in and outside of any building environment that will provide this location data to the cloud.

The bottom line is that the technology advances in BLE, 4G, and now pending 5G will drive down cost in a major way to provide location based accuracy information to the enterprise client. This will enable new business process and improvements that will impact the bottom line.

Wireless Convergence - WLAN, BLE, 4G

View this photo

Over the past now twenty years since 802.11b came into the market in 1999 and the Wi-Fi Alliance was formed in 2000, it has been somewhat the “wild-wild west” in terms of integration of wireless in medical devices.

Manufactures of the SOC in concert with IEEE and the Wi-Fi Alliance have done a great job addressing not only security but also quality of service. This is evident by the global acceptance of Wi-Fi in our mobility world. The author was fortunate be a part of this on the ground floor starting in 1999 working for one of the founders of the Wi-Fi Alliance.

Integra Systems has advocated for over two decades the requirement that any medical device manufacture that decides to use Wi-Fi, conduct ecosystem testing.

This is the only way to validate and verify how the client device performs in a real world environment with security and the proper quality of service. We have written a white paper a couple of years back for www.ixiacom.com that is now a part of www.keysight.com surrounding this. We consider this best of practice that is required for deployments, but also see that is a requirement for regulatory approval.

More and more healthcare applications are using sensors that connect via BLE to a smart phone that often uploads this information to the cloud.

While this is not connected to the IT ecosystem; the Bluetooth SIG has really advanced work to address security and also quality of service.

In terms of BLE and Quality of Service

Robustness of the wireless link is provided by using adaptive frequency hopping, Lazy Acknowledgement, 24 bit CRC, 32-bit message integrity check with a latency of under 6 msec.

BLE Security

Security is provided by 128-bit AES in CCM mode and the application layer is user defined. The Advanced Encryption Standard is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST). AES has been adopted by the U.S. government and is now used worldwide. CCM is a mode of operation for cryptographic block ciphers. It is an authenticated encryption algorithm designed to provide both authentication and confidentiality. CRC (cyclic redundancy check) is used. It is an error detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached based upon the remainder of a polynomial division of their contents. On retrieval, the calculation is repeated and in the event the check values do not match, corrective action can be taken against data corruption. CRCs are good detecting potential errors caused by any noise in transmission channels.

The wireless industry to include manufactures and industry organizations have invested major league over the past twenty years to ensure the proper security and quality of service exists in the enterprise.

Firewalls & Data Diodes - Best Practices for CyberSecurity

Most are very familiar with a software firewall. They are a check off box for network security.

Data diodes were designed on uncompromising technology intended to stop all unauthorized access to nuclear weapon systems.

They enforce a physical separation or "air-gap" between network segments that is enforced by the laws of physics, which are immutable and absolute - data will never be able to flow in the opposite direction, and therefore attackers will never be able to access networks through a data diode.

Integra Systems, Inc. has partnered with Owl Cyber Defense to drive new solutions through the medical device and healthcare space. See attached "What the Difference Between Firewalls & Data Diodes and CyberSecurity Best Practices.
