When designing a “smart” device for the Internet of Things (IoT), you need to ensure that consumers are able to monitor and control their devices from the internet regardless of where its location may be. 

You will need to determine whether your device will use WiFi, cellular, Bluetooth or LoRa. Additionally, there are four technology rating categories to consider: transmission speed, effective distance, power requirement and setup complexity. 

Transmission speed- Transmission speed is the maximum speed that any device will be able to send and receive data. High speeds are critical for transmissions with high data rates such as pictures and video, but less important for low-data streams like text.

Effective distance– Effective distance measures how far from the router the product can be and still be able to send data to it as well as receive data from the server. When designing this product, it is important to know how far it is intended to be from the router while still effectively receiving data.

Power Requirement- Different communication technologies have different power requirements, such as batteries or AC chargers. In some cases, large battery packs or rechargeables may be an option.

Setup Complexity- With some products, especially consumer products, there’s an expectation that any user can take them out of the box, connect them, and be ready to go. However, there are IoT implementations that require a knowledgeable setup team.

Sound Economic FutureWhich IoT Communication Technology Is Best?

WiFi has a high transmission speed and can adequately cover the area of most homes, small business or industrial buildings. It’s a top choice for data-intense streaming. Most devices usually need Alternating Current (AC) power and the setup for it can be done relatively easy, especially if WiFi is already present.

Mesh networks such as Zigbee cost more than simple WiFi and require experts to set up. They have constant power-on requirements and are slower than WiFi but cover more distance, as signals can hop from device to device across the network. Although Bluetooth does not cover much distance, it is inexpensive, simple and battery-operated.Using low power radio-waves bluetooth and bluetooth compatible devices need to be within close proximity of one another to work.

LTE cellular, the technology in smartphones, sets up easily and has high transmission speed. It has to be on a network, so costs can soar with high usage. You would need frequent recharge or massive batteries. LTE cellular covers a lot more distance and is great for remote devices on the move. NB IoT, or narrow band, is cellular that’s more like a landline in that it can’t travel. Since it’s a narrower band it won’t handle as much data as LTE does. It runs best on AC and is good in a non-mobile remote site such as a wind farm.

LoRa (long range radio) is fairly new, and can be thought of as the cable version of cellular. It consumes less power and covers more distance but its bandwidth is limited. The distance can be a little better than cellular and there’s an advantage over cellular and WiFi in that LoRa can travel through metal.
