The challenge of IoT and connected devices is getting data from the device sensor to the cloud, that is, getting access through the internet to where that data is used, processed, and stored. The ubiquitous use of WiFi and Bluetooth through smartphones, along with the widespread availability of cell towers and public WiFi access points, [...]
Cost, power, IP, and latency issues are driving IoT designers away from current standards like Zigbee and toward an emerging set of long-range wireless solutions. LoRa, an abbreviation of "Long Range", is one such technology that is gaining traction. LoRaWAN™ (Long Range WAN) is an emerging LPWAN specification developed by the LoRa® Alliance (www.lora-alliance.org). Like all [...]
With so many multiple wireless standards available, it is sometimes difficult for people to decide which approach is the best for their application, device, or business. At the beginning of each new project, we spend a lot of time understanding the context of the design to identify the important tradeoffs and parameters. This helps us to understand the [...]
As the number of wearable devices increases, the demand for smaller and longer-lasting devices, remote transmitters and transponders, and higher device intelligence will drive the quest for higher energy efficiency and capacity in the power sources of these devices. If we don't continuously improve our batteries, the wearable industry will power down. We are excited [...]
The biggest challenge in wireless medical device is battery life: how to maximize the length of time between charges given the anticipated level of use. One big factor is the power need to transmit the required data volume over the desired distance. To maximize battery life given a target form factor we conserve power by [...]
If you missed Voler Systems at Bay ACM's talk "Sensors, Wearable Devices and Internet of Things", Walt Maclay presented the latest trends and challenges he sees for sensors, wearable devices and IoT, he has a Wearable World News' article at http://wearableworldnews.com/2014/05/21/innovation-trends-sensors-wearable-devices/.
Overview The proliferation of clever apps for almost anything along with the availability of small, inexpensive radio modules and SOC’s (System on a Chip) is enabling and even driving the Internet of Things (IoT). This article deals with applications that require direct communication between the user’s mobile phone and small devices that are a reasonable distance [...]
There is a massive shift happening in tech, everything is getting connected to the Internet. The convenience and power of the Internet makes these products much more valuable, so clients are rushing to get their IoT (Internet of Things) products to market. They rely on Voler expertise in sensors, wireless communication and data collection technology to [...]
