Bluetooth 5 Promises Four times the Range, Twice the Speed of Bluetooth 4.0 LE Transmissions

The Bluetooth SIG is about to officially unveil Bluetooth 5 on June 16 during a media event in London. One change on the marketing side is that they dropped the point number, so it won’t be called Bluetooth 5.0 like in Bluetooth 4.0, but just Bluetooth 5. The decision has been made allegedly to “simplifying marketing, and communicating user benefits more effectively”. On the technical side, Bluetooth 5 will double the speed and quadruple the range of low energy Bluetooth transmissions compared to Bluetooth 4.x, which could be important for IoT applications where nodes are connected throughout the house. Bluetooth 5 will also allow connectionless services to add location-relevant information and navigation. The specifications have not been publicly released yet, and made they will be on June 16. Eventually, you’ll be able to download them on Bluetooth “adopted specifications” page. Via XDA developers Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in […]

802.11ax WiFi Aims to Deliver Higher Throughput (Up to 10 Gbps), Better Handle High Density Scenarios

802.11ax WiFi, also known as High-Efficiency Wireless (HEW), aims to improve the average throughput per user by a factor of at least 4 times in dense user environments, with a total bandwidth of 10 Gbps over 2.4 and 5.0 GHz . The new standard is still work in progress and is expected to be published in 2019. 802.11ax WiFi key features include: Backwards compatible with 802.11a/b/g/n/ac Increase 4x the average throughput per user in high-density scenarios, such as train stations, airports and stadiums. Data rates and channel widths similar to 802.11ac, with the exception of new Modulation and Coding Sets (MCS 10 and 11) with 1024-QAM. Specified for downlink and uplink multi-user operation by means of MU-MIMO and Orthogonal Frequency Division Multiple Access (OFDMA) technology. Larger OFDM FFT sizes (4x larger), narrower subcarrier spacing (4x closer), and longer symbol time (4x) for improved robustness and performance in multipath fading environments […]

OpenThread is an Open Source Implementation of Thread IoT Networking Protocol

Thread was announced about two years ago, as a new IP-based wireless protocol based on 6LoWPAN and 802.15.4 standards and targeting IoT applications. Nest Labs, an Alphabet company, has now released OpenThread open-source implementation of the networking protocol under a BSD license. The source code (C++) for OpenThread includes supports for End Device, Router, Leader & Border Router roles, and can be found on Github. The implementation is said to be OS and platform agnostic with a radio abstraction layer, have a small footprint, and implement all Thread networking layers, namely IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, and Mesh Routing. To quickly get started, you may want to read the Examples README which explains how to build the code, start two nodes, and ping them. Interestingly, while the code is there for everybody to use, only paid members ($2,500 to $100,00) of the Thread group can […]

The USB Type-C Authentication Specification Aims to Prevent Damage from Non-Compliant Cables and Adapters

The new USB Type-C standard is great, as cables are reversible so it does not matter if you connect them up or down, it can handle USB 3.1 data speed, as well as carrying video and up to 100W power thanks to USB-C power delivery. In theory all is great, but in practice, many USB-C cables are not compliant, and Benson Leung, a Google employee, has found that many USB-C cable sold on Amazon were not compliant, with even one damaging his Pixel 2 laptop and two USB PD analyzers. His reviews on Amazon, as well as customer complaints, probably lead the company to ban the sale of non-compliant cable or adapter, but to really mitigate the issue, a technical solution was needed, and that’s why the USB 3.0 Promoter Group has defined the Authentication Protocol for USB Type-C as part of the USB Power Delivery 3.0 specifications. Key […]

M2.COM is a Standard for IoT Sensors Based on M.2 Form Factor

The IoT ecosystem really feels like a jungle now, not because of a lack of standards, but because everybody thinks about doing their own, so we’ve ended up with a wide range of communication protocols, initiatives, and consortia, and it will take some time until the winners and losers are sorted out. One the of the latest standard is M2.COM platform form factor for sensors that “adopts the standardized M.2 form factor and is defined as an evolutionary module that combines general wireless connectivity with additional built-in computing ability powered by MCU”. M2.COM architecture diagram above describes both software and hardware requirements, but the specifications themselves only define the form factor, as well as mechanical and electrical characteristics: Consistent with M.2 standard Module size: 22 mm x 30 mm PCB thickness: 0.8 mm ± 10% Pin count: 75 pins Module input voltage: 3.3V DC-in Connector mating force: 30N Maximum Connector […]

DisplayPort 1.4 To Support 8K Displays over USB-C, 4K@120 Hz, 32 Audio Channels

Just as 4K UHD televisions are getting more affordable with prices ever closer to their Full HD equivalent, the Video Electronics Standards Association (VESA) has published DisplayPort 1.4 specifications with support for 8K QUHD (7680 x 4320) resolution, High Dynamic Range (HDR), video compression and more. Some of the key enhancements or new features of the new specifications include: Up to 8Kp60Hz HDR deep color and 4Kp120Hz HDR deep color Display Stream Compression (DSC) – DSC 1.2 natively supports YCbCr 4:2:0 and 4:2:2 coding, and offers nearly lossless 3:1 compression ratio Forward Error Correction – FEC, which overlays the DSC 1.2 transport, addresses the transport error resiliency needed for compressed video transport to external displays. HDR meta transport – HDR meta transport uses the “secondary data packet” transport inherent in the DisplayPort standard to provide support for the current CTA 861.3 standard, which is useful for DP to HDMI 2.0a protocol […]

WAVIoT LPWAN Technology Powers Low Cost Smart Water and Electricity Meters

With the rise of IoT and M2M applications, more and more Low Power Wide Area Network (LPWAN) standards have been launched or being worked on, such as Sigfox, LoRa, 802.11ah “Hallow”, Weightless, etc… with all promising long range, low power consumption, and support for a high number of nodes. WAVIoT, a US startup founded in 2011, has decided to create its own solution called WAVIoT Nb-Fi (Narrowband Fidelity) that works in ISM bands, offers up to 50km line-of-sight range, supports up to 2 million nodes by gateway, lasts over 20 years on a small battery, and with WAVIoT said to cost as low as $2 per node. The technology is already available in smart electricity and water meters, and modules as shown in the picture below. Here are some of WAVIoT Nb-Fi technical specifications: DBPSK on physical layer of signal transmission; End-nodes transmit radio signal in 10-500 kHz bandwidth Minimum […]

Wi-Fi HaLow is the Consumer Name for 802.11ah Low Power Long Range WiFi

For some reasons, people who decide to name things like to give one name for technical people, and another for consumers. A few years ago, I went to buy a 1080p TV, but at first the seller was confused when I asked, and then I talked about resolution, and when he asked “Full HD” or “HD Ready”? It was my turn to me confused. There are several other example such as Bluetooth Low Energy for geeks may be Bluetooth Smart for consumers, and now the Wi-Fi alliance has just announced that IoT devices and gateway featuring the latest 802.11ah standard will be designed as Wi-Fi HaLow devices. They have not come up with a Wi-Fi Halow logo yet… Nevertheless, apart from the name, nothing appears to have changed. HaLow/802.11ah is still the same Wi-FI standard operating at 900MHz targeting IoT applications with low power, long range (up to 1km), and […]
