Embien has worked with leading communication technologies and has developed IoT gateways providing seamless connected experience.
Embien can choose the right technology based on power, range and pricing requirements
Bluetooth Classic, Bluetooth Low Energy (BLE), ZigBee, WiFi, LoRaWan, SigFox, NFC, simpliciTI, wirelessHART, 6LoWPAN etc.
Amazon AWS, Google AppEngine, Microsoft Azure, IBM BlueMix or proprietary PHP/MongoDB based custom servers
CoAP, LWM2M, HTTP, REST, MQTT, AMQP, STOMP, DDS, Thread, Google Protobufs, UDP etc
Developed customized solutions as well as on top of Intel Atom based designs, NXP iMX based ARM platforms
Smart phones are ideal choice as gateways when the IoT/Wearable device involves BLE connectivity
In the world of Internet of Things (IoT), the end devices are the source of information. These devices collect data from the field and some of them even perform some amount of processing by themselves. But it is important to bring the collected data to a central server application ("Internet" in "Internet of Things") and perform mode powerful calculations, with processing capabilities much larger than the end devices by order of magnitudes. Further data from one node may not give the whole picture where a central server processing data coming from multiple sensors can see them in a bird's eye view.
To transfer data from end device to central server running in cloud, communication interfaces are needed. Many connectivity technologies and protocols are being used or proposed for Internet of Thing communication. While many of today's end devices especially in the fitness wearable segment, have connectivity in form of BLE, this itself is not sufficient to push data to cloud. It needs a intermediate gateway in form of a smart phone. Similarly any communication technology needs a gateway for effective internet connectivity. It is the gateways' responsibility to provide a seamless and secure connectivity between the Cloud and End Device Nodes. It is quiet challenging task to design and develop such connectivity features for devices and gateways, which Embien has been repeatedly taking up and accomplishing successfully.
Since its inception, Embien has been actively using multiple communication technologies in the device designs. Our past experience covers connectivity using Bluetooth Classic, Bluetooth Low Energy (BLE), ZigBee, WiFi. Of late we have been using technologies in LoRaWan, SigFox, NFC, simpliciTI, wirelessHART, 6LoWPAN etc. With its rich experience, Embien can rightly choose the technology based on the power, range and pricing requirements on the design.
We also have worked with higher protocols like CoAP, LWM2M, HTTP, REST, MQTT, AMQP, STOMP, DDS, Thread etc. Our designs can eliminate unnecessary data overhead by using efficient encoding mechanisms and protocols like Google Protobufs, MQTT, CoAP, UDP etc.
It is essential for the IoT gateways to provide seamless connectivity even if the end unit is highly mobile. With careful antenna design both at the end device and at gateway, it is possible to extend the range as much as possible. Embien has worked on multiple gateway designs covering different communication technologies. In creating cases, we have leveraged many available platforms including Intel Atom based designs, NXP iMX based ARM platforms for rapid development of gateway. Third party tools like LinkLab LoRa Gateways are also incorporated in our designs. Embien has carried out extensive work with smart phones as gateways and developed mobile apps for Android and iOS to complete the last mile of connectivity with BLE.
Our gateway designs have been used to create bidirectional data transfer between end devices and Cloud platforms like Amazon AWS, Google AppEngine, Microsoft Azure, IBM BlueMix or proprietary PHP/MongoDB based custom servers. Embien ensure that right security measures are applied to make sure the data transferred is not subjected to malicious attacks. Our designs are tolerant of intermittent loss of connectivity which is unavoidable in field conditions and make sure that the data is not lost or at least source indicated of failure to delivery. In few cases, redundant communication channels are provided at gateway for assured internet connectivity.
Embien weaves together a smooth usage experience such that the devices are "Internet" enabled all the time irrespective of their place or position. Get in touch with us to design a seamless IoT Communication experience for you and your customers.
