Hologram LTE Software-Defined Global Network for Cellular IoT Projects Starts at $0.40 per Month per Device

July 26th, 2017 15 comments

Cellular connectivity can be rather expensive, and in the IoT realms, new LTE standards are still evolving and you may want to manage your own mini cellular network, so ideally we would need a provider that offers both low cost and flexibility. Hologram LTE network does both as it’s a software-defined network, and pricing starts at $5 for the SIM card and $0.40 per month per device.

Global IoT SIM Card

The company also just announced that their network was available for global deployment with the service available in more than 170 countries via partnerships through over 200 cellular carriers. The SIM card supports automatic roaming and carrier switching, and spacebridge inbound tunnel access allows for secure remote programming and device management.

The SIM card specifications are as follows:

  • 2G/GPRS, 3G HSPDA, 4G LTE
  • Read/Write Cycles: Min. 500,000
  • Operating Temperature: -25°C ~ 85°C
  • Data Retention: Min. 25 years at 25°C
  • Triple-cut for Mini, Micro, and Nano SIM formats
    • Mini: 15 x 25mm
    • Micro: 12 x 15mm
    • Nano: 8.8 x 12.3mm

Pricing is divided into zone 1 (cyan) and zone 2 (purple blue) depending in the country where the SIM card operates, with the latter being more expensive.

Within each zone there are two pricing methods, with pay-as-you-go plans with a fixed platform fee per month plus a charge per megabyte, or monthly  plans with a fixed amount of data. For example, a SIM card in zone 1 would cost a $0.40 platform fee per month plus $0.60 per megabyte (charged per KB), or $3.99 for 10MB of data, while a SIM card operating in zone 2 would be $0.40 platform fee per month plus $0.85 per MB, or $6.99 for a monthly 10MB plan. You can also choose monthly plans with less or more data up to 500MB per month, except in the US where the company offers high bandwidth monthly plans up to 5GB per month. Inbound SMS are free, and outbound SMS cost $0.19 per MB or $0.30 per MB depending on your zone. You’ll find all details on the pricing page.

While the SIM card costs $5, you can try the service for free by “purchasing” a developer SIM card that comes with 1MB data per month. I ordered one with DEVPLANBLASTOFF promo code for free shipping. I’ll see if I ever receive it, and whether I can use it where I live, since in theory all SIM cards must be registered with an ID card or passport to work, and mandatory fingerprinting is coming next year.

You can certainly use the SIM card on your own hardware, but the company can also provide Hologram Dash board based on Ublox Sara-U260 2G/3G module, and kits such as the one above with components, sensors, cables, and other accessories. The documentation explains how to get started with Dash board, the SIM card, and cloud messaging and APIs.

Hologram is not the only company offering pay-as-you-go and monthly plans for cellular IoT, as Particle (previously Spark) has offered an inexpensive monthly plan for a little while, but it does not relies on an SDN implemtation. You’ll find further information and details on Hologram website.

mangOH Red hardware design is fully open source with BoM, schematics (PDF an Allegro/OrCAD), PCB Layout (Intercept Pantheon), Gerber, and mechanical files available for download in the resources section, where you’ll also find other documentation and getting started guides for users and developers.  The CF3 modules run Legato Linux developed by Sierra Wireless, and open source with the source code on Github. Code specific to MangOH Red + WP8548 was also upstreamed in Linux 4.10.

The company also offers Sierra Wireless Smart SIM with up to 100 MB free data, but you can use the board any commercially available SIM car. The board also supports AirVantage IoT Platform to create, deploy and manage solutions in the cloud.

MangOH Red board can be purchased as a bareboard, but most people will probably want to get a Starter Kit with MangOH Red plus Air Prime WP8548, WP7502 or WP7504 sold on Digikey. I’m very confused by the price list, as $99 is shown for both the bare board, and kits including the board and a CF3 module. So I’ll assume $99 is for mangOH board only, and you’d likely have to pay $200+ for a board plus a CF3 module with the total price depending on the selected module. You may find additional details on MangOH Red product page.

Samsung S-Patch3 Wearable Health Tracker Based on Samsung Bio-Processor Hits the FCC

June 9th, 2017 No comments

At the end of 2015, Samsung unveiled their S3FBP5A Bio-Processor comprised of an ARM Cortex-M4 MCU, a DSP, and sensors for PPG, ECG (electrocardiography), Skin temperature, BIA, and GSR to have a single package to design tracker able to monitor your health condition. The company demonstrated an early prototype called S-Patch at CES 2016 (See embedded video at the end of this post), and now S-Patch3 wearable health monitoring system has just hit the FCC.

The system has two round shapes case connected via a cable, with one for the battery compartment, and the other containing the Bio Processors, and meant to be placed on your chest. The device can then synchronize the data with your smartphone in real-time over Bluetooth. People with heart conditions may benefit from the system, as if they wish to do so, they could share the data with their doctor. Few documents are publicly available on the FCC website, and while we don’t know the expect launch date of the device itself, the user’s manual and photos will be released on December 3rd, 2017 on the FCC website, which should roughly correspond to the launch date, or at least the official announcement date from Samsung.

8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

May 23rd, 2017 No comments

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted.  That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon.

8Power LTE NB-IoT GPS Tracker (Left) and MEMS Sensor (Right)

The company has recently announced their Track 100 family of LPWAN GPS tracker, such as Track 100XL relying on LTE NB-IoT, but they also have models supporting LTE Cat M1 and LoRaWAN. The IP67 devices include vibration energy harvesting technology, as well as optionally a solar panel. The company also provides a “secure cloud hosted data platform to provide dashboards, analytics, device management, security and application API access to manage fleets of devices”. There’s no battery, and no need for (battery related) maintenance. Track 100 trackers are powered through the vibration generated by trucks, trains, or other vehicles.

The company is also working on integrating the technology into MEMS sensors that consume very little power (10 mW) in continuous operations. Beside leveraging vibrations from the transportation industry, and 8Power technology can also generate power from vibrations from  infrastructure (bridges, embankments, transmission lines) or machinery (high-power motors and rotating equipment), and the technology has already been validated through a experiment to monitor the structure of an older bridge in Scotland.

The company showcased their technology and latest products at IDTechEx 2017.
