Amazon Sidewalk – A Low Bandwidth Network For Connecting Smart Devices and IoT

In 2019, Amazon introduced the Sidewalk with privacy and security at the core. Amazon Sidewalk a low-bandwidth, long-distance wireless protocol that is expected to provide a new way for devices to stay connected especially when smart devices leave their WiFi or Bluetooth coverage range by leveraging the 900 MHz spectrum. Amazon Sidewalk will most likely be an LPWAN type network since it is promising neighborhood-like device connectivity with is crowdsourcing initiative. It uses Bluetooth Low Energy (BLE) for short distances, the 900 MHz spectrum, and other frequencies for longer distance coverage. Sidewalk attempts to make sure your BLE devices can still connect to your home network even when you take a walk away from your home. According to Amazon, users can easily access the Sidewalk network using two types of devices: Sidewalk Bridges and Sidewalk-enabled devices. Amazon has now announced that compatible Echo devices can now act as bridges and also some […]

MIOTY Silicon Vendor Agnostic, Scalable LPWAN Standard to Take on LoRaWAN, NB-IoT

[April 6th update: The article was updated to reflect Fraunhofer invented the technology] There are plenty of LPWAN (Low Power Wide Area Networks) standards designed for low power, low bitrate and long-range connectivity with the most popular currently being NB-IoT and LoRaWAN. But Texas Instruments has joined other smaller companies (Fraunhofer, Ragsol, STACKFORCE, WIKA…) to form the MIOTY alliance in order to develop and promote a new LPWAN standard operating in the sub-GHz range called MIOTY. Texas Instruments explains MIOTY was born due to a lack of scalability and robustness (interferences issues) of current LPWAN solutions. But just like other similar low power WAN standards, it aims to support long-range while achieving long battery life, but MIOTY is also supposed to help IoT developers mitigate performance degradation in high-node-count networks. MIOTY works in the same license-free bands (868 MHz, 915 MHz …) as LoRa radios with no costs involved to […]

reMarkable 2 is a $399 e-Paper Tablet with Pressure Sensitive Pen

reMarkable digital notepad and e-reader was unveiled in 2016, and designed to feel like using actual paper sheets. The device came with a single-core Cortex-A9 processor, a 10.3″ E-Ink display with 1872×1404 resolution, and WiFi connectivity to backup your notes and/or drawings to the cloud or mobile phone. The company is now back with reMarkable 2 e-Paper tablet equipped with a faster and more efficient dual-core Cortex-A7 processor, 1GB RAM, a second-generation CANVAS 10.3″ e-Paper display with the same 1872×1404 resolution but lower latency. The second-generation e-Paper tablet also benefits from a thinner design and much-improved battery life. reMarkable 2 specifications: SoC – Dual-core Arm processor @ 1.2 GHz (possibly NXP i.MX 7Dual processor) System Memory – 1GB LPDDR3 RAM Storage – 8GB internal storage good for around 100,000 pages Display – 10.3″ monochrome digital paper “CANVAS” capacitive touch display partially based on E-Ink Carta technology with 1872×1404 resolution (226 […]

XMOS launches Xcore.AI, a scalable AI processor for the Edge

XMOS, known for its high-performance voice interfaces, is joining the AIoT bandwagon with the announcement of the Xcore.ai, a flexible and economical processor delivering high-performance AI, DSP, control, and I/O’s in a single device. IoT and AI have been one of the most trending topics and fields in the last decade. Both areas have seen large innovations in between them. Deep neural networks have become better, IoT deployment cost has also been greatly reduced, and most importantly, they both have a significant impact on multiple industries. An interesting trend recently is the emergence of applications merging AI and IoT together to form so-called AIoT applications. IoT will be the digital nervous system, while AI will become the brain that makes all the critical decisions which will control the whole system. AIoT has led to the development and deployment of what we call AI processors or AI modules that can be […]
