The case for Long Range in Smart City : Zigbee or LoRa?

#Discussion(IoTStack) [ via IoTForIndiaGroup ]

Start-ups using Zigbee report range up to 3Km?

Is that good-to-go for Smart City and Comemrcial implementaions?

The Zolertia ReMote platform is unique in that it provides both a 2.4 GHz SoC (TI CC2538) and a sub-GHz radio chip (TI CC1120). This makes it possible to use it both for shorter range 2.4 GHz communication and long-range sub-GHz networking. For example, in this test, the ReMote was able to achieve an impressive 3.14159 kilometer transmission range.

The ReMote platform also has a number of expansion ports, including two Phidget ports for external sensors and other devices.
Revolutionary feature: Contiki mesh + Bluetooth beacons
The TI CC26xx platform is the dual IEEE 802.15.4 and Bluetooth radio, which makes it possible to do both Contiki IPv6 meshing and Bluetooth beacons – at the same time. Bluetooth beacons can be picked up by iOS and Android apps.

This allows Contiki devices to be discovered with an iOS or Android smartphone app, without any additional hardware or software. This is revolutionary as it makes user onboarding both quicker than ever before, but also significantly more secure.

The Thingsquare platform, a commercial connected product platform that uses Contiki, use this to securely discover and authenticate nearby devices which then use the low-power mesh for data access, through a smartphone app.
