Android’s 3D mapping aided GPS enables improved urban GPS accuracy

One of the best features of smartphones is GNSS location with standards like GPS that allows you to get directions or share your location with friends or business contacts. It works great in most cases, but getting an accurate location may be challenging in urban areas due to tall buildings that block the signal to the satellites and create reflections. This can be an issue for ride-sharing apps for example, as the applications may detect the wrong side of the street you are on, either forcing the client to cross the street (when possible) or the driver to take a detour to reach your location. This problem may soon go away in Android phone thanks to 3D mapping aided GPS corrections. So how does that work exactly? Google explains: The 3D mapping aided corrections module includes tiles of 3D building models that Google has for more than 3850 cities around the world. Google Play services 3D mapping aided corrections currently […]

Raspberry Pi Gets 5G Cellular Connectivity with Snapdragon X55 Powered HAT

The Raspberry Pi board has long been able to connect to cellular networks either via USB dongles or 3G or 4G LTE HATs that often include GPS as a bonus. But you can now connect your Raspberry Pi 4 or other RPI SBC with a 40-pin header to 5G networks thanks to Waveshare SIM8200EA-M2 5G HAT for Raspberry Pi powered by Qualcomm Snapdragon X55 multi-mode multi-band modem offering 5G/4G/3G cellular connectivity. As we can see from the photo, the 5G add-on comes as part of a cool-looking kit with bottom and top acrylic plates, spacers, a cooling fan plus five antennas for cellular and GNSS connectivity. But the HAT itself integrates a SimCOM SIM8200EA-M2 M.2 module and offers the following specifications: Compatibility – Works with Raspberry Pi boards with a 40-pin GPIO extension header Cellular Connectivity SIM8200EA-M2 core module based on Qualcomm Snapdragon X55 platform with multi-mode multi-band support 5G/4G/3G networks support SIM card slot compatible with 1.8V / 3V […]

Tiny, Waterproof AirBolt GPS Tracker Works with LTE-M and NB-IoT Cellular Networks (Crowdfunding)

We’ve previously covered small waterproof LTE Cat M1 and NB-IoT GPS trackers such as Mictrack MT825, but AirBolt GPS tracker offers another option and promises an even longer battery life of up to 12 months. At 37 x 34 x 11mm, AirBolt GPS may also be the world’s smallest waterproof GPS tracker on the market, as well as the lightest at just 21 grams, both of which are characteristics that make the tracker especially suitable for pets like cats and dogs, as well as track luggage, keys, bicycles, etc… AirBolt GPS tracker key features and specifications: SoC(s) Unnamed, but considering Nordic Semi is listed as a partner it should be nRF9160 SiP with Arm Cortex-M33 MCU core, 1024 KB flash, 256 KB SRAM, NB-IoT, LTE Cat M1, and GPS connectivity There’s also Bluetooth 5.1 so one of the nRF52 chips might also be included. Connectivity Bluetooth 5.1 with long-range and direction-finding support Cellular – Worldwide support via NB-IoT and LTE […]

Review of FamiSafe Phone Tracking & Parental Control App (Sponsored)

CNXSoft here. I’ve been tasked with reviewing Famisafe parental control app for Android and iOS acting both as a parental control app and phone tracker app and designed for parents who want to track their kids’ location and better control when to use the phone and what content they may access. The first thing to get started is to download the free trial on either Android or iOS. I actually downloaded both versions for FamiSafe for this review, since I used Huawei Y9 Prime 2019 (Android 10) as the “parent” smartphone, and an iPhone 6 as the “kid” phone. Famisafe Initial Configuration We’ll have to start with the “parent” phone. After a welcome screen explaining some of the main features including offensive content detection, device & app usage rules, web filter, etc.. you’ll be asked to select whether it’s the parent or kid device. Once we select “Parent” we’ll be shown the differences between the Free and Premium version. The […]
