With the generational change of Internet of Things, new ways and needs of intercommunicating devices have appeared. Until recently, wireless technologies were designed to transmit through a big bandwidth and without taking account of power consumption. The new paradigm of IoT devices, that require low bandwidth and power consumption, has facilitated the emergence of new wireless technologies that completely fit the needs of these devices.

Below, we detail the main advantages and disadvantages of the best technologies of connectivity of Internet of Things:

 

Technology Advantages Disavantages
 NB-IoT  Very low power
 Low cost of modules and chipsets
 Excellent indoor penetration
 Encrypted
 Dedicated bandwidth
 Not interoperable with any existing infrastructure
 LTE-M (CAT-M1)  Interoperable with existing 4G devices and networks
 Prepared for roaming devices
 Encrypted
 Optimized for bigger bandwidth
 Moderately expensive
 LoRa  Allows private networks with radius of 15 km
 Bidirectional communications
 Encrypted
 Very low data rates for some applications
 Not ideal for moving applications
 Sigfox  Lowest bandwidth costs
 Lowest power requirements
 Limited to Sigfox networks (mostly Europe)
 Not bidirectional
 Not suitable for mobility apps
 No encryption
 BLE  Low power consumption
 Lower cost of modules and chipsets
 Complete integration with smartphones
 Bidirectional communications
 Encrypted
 Range limitation similar to Wi-Fi
 Not suitable for mobility apps

 

These technologies have been designed to led to a large number of business and innovation opportunities and each one has their strengths and weakness, so the best IoT technology will depend on the application and key features needed on the field.

Pay attention when choosing your IoT technology; and if you're thinking about developing your own IoT device and you have doubts about the best technology then first contact us! We will be very glad to help you.
