Q: What is the range of Sub 1-ghz devices ? how much will the range be greater then Wi-Fi?
Sub-1 GHz devices have much greater ranges than Wi-Fi devices. The Range of the sub-1 GHz devices can be over 1 km while Wi-Fi range is closer to 100m.
Q: If I want to use Sub 1GHz on my MCU/edge device, what do I need to transfer data from the edge device and eg a Linux based gateway device? Thx. I mean what do I need on the gateway?
Here is software information for TI’s Sub 1GHz solution - http://www.ti.com/lsds/ti/wireless_connectivity/sub-1_ghz/tools_software.page#simpliciti
Q: Are there any GMS based products focused on IoT (low power)?
TI has many wireless technologies including Wi-Fi, Bluetooth, Zigbee, 6LowPAN, Sub 1Ghz and more. GSM is not supported in our portfolio.
Q: Does TI have any portfolio of sensor's like moisture, humidity or some chemical sensors for farming applications ?
TI does have moisture/humidity, temperature, and chemical sensors. We also have reference designs that are targeted at similar applications to farming. For example, The Gas Sensor Platform Reference design with Bluetooth low-energy (BLE) is intended as a reference design that customers can use to develop end-products for consumer and industrial applications to monitor gases like carbon monoxide (CO), oxygen (O2), ammonia, fluorine, chlorine dioxide and others. For more information see TI’s web - http://www.ti.com/lsds/ti/analog/sensors/overview.page
Q: I am currently programming on TI Tiva C series mcu's. What are the difference in programming CC3200 and TI Tiva C processor?
Both the CC3200 and the Tiva contain ARM-M4 processors so they have a lot in common. However, there are software tools designed specifically for the CC3200, but the IDE tools were derived from Tiva tools so there are several similarities.
Q: What LaunchPad / MCU would you suggest for application which want to use Wi-fi and sensor mesh network ( much like Zig bee) but not as costly as Zig bee?
The only other mesh network that TI offers is 6LoWPAN. However, I would strongly urge you to consider ZigBee. TI already has a Wi-Fi to ZigBee gateway designed that is much easier to build off of. Here is a link: http://ap-fpdsp-swapps.dal.design.ti.com/index.php/Low_Cost_ZigBee_WiFi_GW
Q: Regarding on both ends (edge and gateway) the Sub 1GHz, if I want a Linux based gateway are drivers provided that support Linux?
Linux drivers are not provided today, but stack is available online for MCU - http://www.ti.com/lsds/ti/wireless_connectivity/sub-1_ghz/tools_software.page#software
Q: Great presentation! Is there a (low memory footprint) 6LoWPAN stack you recommend, for MSP430 microcontrollers?
Here are some options. Look at TI web for how to get started – look down the page for getting started section - http://www.ti.com/lsds/ti/wireless_connectivity/6lowpan/overview.page
Q: What connectivity model would you recommend for highly mobile applications? 10+ kms
Sub-1 GHz has the greatest range, and can support ranges in over 10km. Another option might be to look at cellular.
Q: When using Wifi based MCU/edge devices I would think MQTT is a good option. What do you recommend for other communication means?
MQTT is good communication means. TI has a great cloud ecosystem where our partners have communication solutions built on TI products. http://www.ti.com/lsds/ti/wireless_connectivity/support.page?keyMatch=cloud%20ecosystem&tisearch=Search-EN#cloudecosystem
Q: Any particular recommendations for the sub1 or cellular (What are the advantages / disadvantages of each?)
Sub-1 GHz can run on very low power, and enables a relatively low throughput. The sub-1 GHz frequency band is less crowded. It requires a larger antenna and there are restrictions on duty cycles at certain frequencies. You basically create your own network with both nodes and network and services. This solution is supported with standard products available for TI and distribution.
Cellular is owned by carriers so you would need to work with them to leverage their network and any services.
