Digi XBees Work to Transform Package Delivery with Connected Lockers

Posted on:

How many times have you missed an anticipated package delivery only to wait days for that one moment when the stars align and the delivery comes while your home? Or maybe that special moment never comes, and the package you’ve been waiting for is returned to its sender.

SmartBox Co., Ltd. is revolutionizing the distribution industry to solve that problem. The company, founded in 2013 and headquartered in Seoul, Korea, manufactures the “SmartBox,” a high-tech locker that applies IoT technology for unattended parcel delivery. It’s the world’s first Internet of Things-based delivery locker. And unlike traditional kiosk lockers, the SmartBox is more convenient, independent, and economical.

SmartBoxWhen parcel arrives, the delivery-person enters a mobile number and places the package in a secure locker. The recipient gets an SMS message with a password to open the secure locker.

Using Digi XBee® wireless modules and gateways, SmartBox can work with either unmanned delivery destinations or traditional lockers. Each SmartBox locker is equipped with an XBee module that provides connectivity and intelligence to permit/forbid access to lockers based on single-use codes. A single Digi XBee gateway carries backhaul traffic to SmartBox’s operations center where lockers can be monitored and maintained centrally. That gateway also sends SMS notifications to package recipients. More than 3,000 SmartBox lockers have been installed in apartments, college dormitories, public offices, office buildings, and subway stations across South Korea and Japan.

What Makes Thread a Secure Wireless Protocol?

Posted on:

With XBee Thread soon arriving, we’re fielding a lot of questions regarding the protocol’s touted security benefits. Not only does Thread provide a robust network with no single point of failure, but it also offers businesses and developers extremely secure wireless communication. Let’s look at a couple reasons why.Web

IP-based Security Protocols
Yes, it’s a low-powered network, not unlike ZigBee and other 802.15.4 radios, but it’s also IP-based. This is important because with an IP-based networking protocol, developers can tap into security protocols used when you’re browsing the internet. Some of the common ones are DTLS, TLS and SSL. These IP-based security protocols provide the network with secure end-to-end communication.

Commissioning
Another benefit of the Thread protocol is the commissioning process. Commissioning is the process of joining a new node to the Thread network. Previously, this could lead to network vulnerabilities and be overly complex. But, the creators of Thread have made it a straightforward and user-friendly experience by leveraging mobile technology and passphrases. This ensures no rogue nodes are able to join the network without being overly complex.

There are three ways to add a node to a Thread network, out-of-band commissioning, discovery, and through a commissioning application on a mobile device.

Out-of-band commissioning mode configures a node with the network credentials of the desired network. This makes the node behave like a partition of the network.  When it comes in range of the network, it will be like two partitions joining into a larger network creating a secure handoff.

When commissioning via discovery mode, the node searches for a network with matching credentials. For this, the security is simple, the network must be in range of the the node, the network must allow joining, and the node must be told to expect a node to be joining, identified by its EUI 64, or unique IPv6 MAC address.

Lastly, Thread introduces a third method, and arguably the easiest new way to commission a device, through a commissioning application installed on a device such as a smartphone, tablet, or laptop.  Thread describes this process as petitioning and joining.

Petitioning is the process of authenticating and authorizing the commissioning device (like your phone or laptop), which will run the Thread commissioning app. The device can then communicate with the Thread network either locally or via the internet through the network’s Border Router. This forms a secure TLS connection between the network’s Border Router and the user’s commissioning device.

So now that we’ve got our commissioning device authorized, how do we add a new node to the network? It’s pretty easy.

When a node wants to join the network it will send a request to the commissioning device where the user will be prompted to enter a key to authorize the node(s) to join the network. Once the key is entered, there is a secure DTLS handshake between the joining node and the Commissioner. The new node receives the network parameters and is all ready to function with the necessary rights and privileges.

This is just a brief look at why many IoT experts consider Thread a more secure wireless protocol based on its security features and commissioning process. Check out these resources to learn more about the Thread wireless protocol:

What Are the Differences Between DigiMesh® and ZigBee® Mesh?

Posted on:

Mesh networking is a powerful way to route data over an RF network. Range is extended by allowing data to hop node to node and reliability and resiliency is increased by “self-healing,” or the ability to create alternate paths when one node fails or a connection is lost.

One popular mesh networking protocol is ZigBee®, which is specifically designed for low-data rate, low-power applications. Digi offers several products based on the ZigBee protocol. Additionally, Digi has developed a similar mesh protocol named DigiMesh®. Both ZigBee and DigiMesh offer unique advantages important to different applications. The following chart highlights these differences:

ZigBee® Mesh DigiMesh®
Node types and their benefits Multiple: Coordinators, Routers, End Devices. End devices can sometimes be less expensive because of reduced functionality. Single: One homogeneous node type, with more flexibility to expand the network. DigiMesh simplifies network setup and reliability in
environments where routers may come and go due to interference or damage.
Battery Deployed Networks Coordinators and routers must be mains powered All nodes are capable of battery operation and can sleep. No single point of failure associated with relying on a gateway or coordinator to
maintain time synchronization.
Over-the-air firmware updates Yes Yes
Range Most ZigBee devices have range of less than 2 miles (3.2 km) for each hop. Available on XBee SX with range of up to 40+ miles for each hop.

Olsbergs Uses XBee to Make Construction Sites Safer

Posted on:

Olsbergs is a leading manufacturer of electro-hydraulic control systems for cranes. Olsbergs was looking to improve efficiency and safety for construction crane companies and crane operators. They wanted to turn to radio remote-controlled hydraulics. They needed a partner that would meet ETSI standards, as well as the high standards of their own company.

Digi was the company that they turned to. Olsbergs needed a radio module that would be risk-free and precise. With so many of their trucks being used in cities and other populated areas, risk had to be minimized as much as possible. It would have to utilize the entire ISM band to enable more channels and provide more security. The solution was the XBee 868 Low-Power RF module for Europe.

With their new remote controlled hydraulics, truck cranes which previously required two operators, a spotter and a driver, now only require one. With Digi’s help, Olsbergs has improved safety, accuracy, and reliability for crane operators, while reducing costs and saving money for construction companies.
