Star and Mesh Networks

The most common configurations for connecting multiple devices are the star and mesh networks. Star Network In its simplest form, a star network consists of one central hub which acts as a conduit to transmit messages. In a star topology, every device is connected to a central hub. Advantages If one node or its connection [...]

Getting Data into the Cloud

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, [...]

LoRaWAN

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 [...]

IoT based on ARM processor and TI CC3200 Wifi Module

We recently delivered two different IoT projects that were both based on the TI CC3200 Wifi Module with an ARM Cortex-M4 processor. We selected the ARM Cortex-M4 because it's low-power 16-bit processor was ideal for our real-time application.  The TI module nicely integrates the ARM processor, wifi block, timers, the Analog-to-Digital Converter (ADC) channels, and [...]

ReadWrite: How Does Sensor Data Go From Device To Cloud?

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 [...]

Batteries Holding Back Wearable Devices Article Featured on ReadWrite

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 [...]

Power, Power, Power

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 [...]
