Sigfox Targets Worldwide Coverage with Satellite Launch

Sigfox Satellite

LPWAN technologies such as NB-IoT, Sigfox, and LoRa deliver low power, long range communication at low bitrate and can be used for asset tracking, environmental monitoring, water & electricity meters, and so on. The line-of-sight range between the closest gateway and nodes is usually 10 to 20 km, and coverage can be expanded by connecting several gateways to form a network. However, this is not workable in all locations worldwide, so Sigfox plans to launch a Sigfox satellite in collaboration with Eutelsat in order to provide coverage in places like large deserts such as the Sahara desert, the two poles, as well as oceans as explained by Franck Siegel, chief operating officer at Sigfox. This will for instance enable tracking and monitoring of oil platforms and vessels. The press release does not explains much except Sigfox and Eutelsat will test the first Satellite in H2 2019 before the commercial launch of the “ELO” constellation in 2020.

GearBest Database Was Left Unsecured For 2 Weeks

gearbest unsecured database

GearBest is one of the most popular Chinese online stores, and we often feature products sold by the company on the website. However, VPNMentor research team headed by Noam Rotem, a  hat hacker and activist, discovered a serious security breach in Gearbest, where their database was completely unsecured for a period of time. Specifically the research team was able to access the following databases in March 2019: Orders database with products purchased, shipping address and postcode, customer name, email address, phone number Payments and invoices database with order number, payment type, payment information, email address, name, IP address Members database with name, address, date of birth, phone number, (unencrypted) email address, IP address, national ID and passport information, (unencrypted) account password They discovered 1.5+ million records in total. They managed to login successfully to two accounts from the database breach for testing. Payment information included data related Boleta (used in Brazil) and Oxxo (used in Mexico) which would allow potential …

How to Import Google+ Account and Communities to MeWe

Google+ Export Data

Google+ for consumers is going to definitely shutdown on April 2nd, and as written previously I had been looking for an alternative, and ended-up going with MeWe Ad-free, Privacy Focused Social Network. I created my own account, as well as two groups for development boards & SBCs and mini PCs & TV boxes. Many users have joined MeWe because of Google+ upcoming closure, so it made sense for the company to create an importer so that all posts, and communities can be imported from Google+ into MeWe. Mark Weinstein, MeWe CEO & founder, has now announced the release of Google+ Importer and instructions in a PDF sadly written in Microsoft Word… The steps are fairly simple: Go to https://takeout.google.com and click on “Deselect All” Select Google+ Circles, Google+ Communities, and Google+ Stream (apparently Google+ Likes is not needed), and make sure to check the format to JSON whenever possible as shown in the screenshot below. Click Next Step, and make …

Cost of Mobile Data Around the World

Cost of mobile internet per country

The price of products often vary around the world due to taxes, regulations, and cost of living. In many cases, that’s just a few tens of percents, but in some others the price may vary a lot more, as in many folds. For example, medicines are usually way more expensive in developed countries – and harder to buy -,  and based on a study by Cable.co.uk, the price of 1GB mobile data varies massively across the world with India having the cheapest average cost of $0.26 US, and Zimbabwe the highest at $75.20. Price varies a lot even for neighboring countries. So if you live in Geneva in Switzerland where the average price for 1GB is $20.22, it may pay off to get signal from France (if possible) where the average cost is only $2.99. One should bear in mind that determining the average price of 1GB of mobile data is not that easy. The company gathered information from retail …

Cellular Forecasts for 2024 – 1.5 Billion 5G Subscriptions, 4 Billion Cellular IoT Devices

Mobile subscription forecast 2024

5G has yet to really take off, as it’s only available in a few cities,  but a recent report publishes by Ericsson provides some forecasts for the future of 5G and cellular IoT connectivity, as well as interesting numbers of the current state of cellular networks. There are now 7.9 billion mobile subscriptions, more than humans, including 5.7 billion mobile broadband subscription, with Asia clearly dominating the field due to its much larger population. Asia also accounts for most of the recent growth in subscriptions, and interestingly people in Central and Eastern Europe (including Russia) especially appears to need more than one mobile subscription with 142% penetration, which means on average one person has 1.4 mobile subscriptions. There are more subscriptions than people in most of the continents/countries, but to a lesser extent, and India (87%) and Africa (82%) are the only exceptions. The chart above allows us to look at both the current trends and the future. We can …

MeWe is an Ad-free, Privacy Focused Social Network

MeWe CNX Software

This post will be fairly off-topic, but recently Google announced they’d be closing Google+ for consumers. CNX Software has a community about TV boxes and mini PCs with over 12,000 members on the site, and that means it will go away eventually. So Google+ is going away, Facebook is very popular – and we have our own page – but many people have privacy concerns, don’t like the way the company handles their data, and/or for sensitive subjects, censorship appears to have come into play recently. Twitter is another option which I also use, but there’s no such things as groups or communities. But the other day, I noticed people on Google+ complained about the lack of activity in a specific community, and a person replied that everybody moved to MeWe… OK, so what is MeWe? As described on the website: Engineered with privacy-by-design, MeWe turns the table on Facebook and other social media companies with a revolutionary service that …

1NCE to Offer a 10 Euros Plan for 10-Year of Cellular IoT Connectivity in Europe

For the Internet of Things to be successful, prices need to come down sharply, and eventually LPWAN connectivity should be possible with $1 to $2 modules, $5 to $10 development boards like we can get for WiFi today. Cellular IoT hardware is likely to be a bit more expensive – even when using NB-IoT – but hardware prices have to come down to acceptable levels, and so is connectivity. 1NCE brings us in the right direction for the latter with a SIM card selling for 10 Euros offering 10-year of 2G/3G/NB-IoT connectivity (1 Euro per year) with 500MB data included.  That’s about 140KB of data per day, which should be OK for applications like smart meters. There are no other fees, except if your device goes over the limit,  but the company has not provided any pricing details for the extra data. The service will cover 30 countries in Europe. The SIM cards will start selling in August 2018, and …

Khronos Group Releases Neural Network Exchange Format (NNEF) 1.0 Specification

The Khronos Group, the organization behind widely used standards for graphics, parallel computing, or vision processing such as OpenGL, Vulkan, or OpenCL, has recently published NNEF 1.0 (Neural Network Exchange Format) provisional specification for universal exchange of trained neural networks between training frameworks and inference engines. NNEF aims to reduce machine learning deployment fragmentation by enabling data scientists and engineers to easily transfer trained networks from their chosen training framework into various inference engines via a single standardized exchange format. NNEF encapsulates a complete description of the structure, operations and parameters of a trained neural network, independent of the training tools used to produce it and the inference engine used to execute it. The new format has already been tested with tools such as TensorFlow, Caffe2, Theano, Chainer, MXNet, and PyTorch. Khronos has also released open source tools to manipulate NNEF files, including a NNEF syntax parser/validator, and example exporters, which can be found on NNEF Tools github repository. The provisional NNEF …
