Smart home: I believe we are no longer strangers to it! Then we choose a smart home when in the end should choose with WiFi module or Bluetooth module?
Look at your home have what smart home it?
1, morning and evening a key to switch the curtains, 2, remote cooking, 3, remote switch air conditioning, 4, a key to open the door, 5, 6, ……….
In these smart homes to go to use its functions, basically can not be separated from the WiFi module and Bluetooth module!
Then we choose the smart home in the end should choose with WiFi module or Bluetooth module?
We judge from the following 6 points
A power consumption
Bluetooth 5.0 transmitting power and standby power consumption is low compared to WiFi, in standby mode, with 1 device sharing, Wi-Fi sharing an hour average power consumption of 10%, but Bluetooth power consumption is WIFI 1/3.
Bluetooth also provides two layers of password protection, while the security risk of WiFi is the same as other networks, once someone obtains partial access to the entire network. In terms of security, Bluetooth 5.0 is better than WiFi.
Three communication distance
Traditional Bluetooth effective distance of about 10 meters, Bluetooth 5.0 can reach up to 150 meters; WiFi effective distance is generally 50 ~ 100 meters. So in terms of distance WiFi effective distance wins over traditional Bluetooth!
Bluetooth 5.0 small size, low cost than WiFi module.
Five mutual interference
Bluetooth 5.0 has a stronger anti-interference ability, especially for Wi-Fi and LTE signals, to a certain extent to avoid the limited space “signal blockage”, mutual interference is lower than WiFi. however, Bluetooth and WiFi are using the 2.4GHz band, the band is quite crowded. To reduce signal interference, many users will choose the 5GHz band Wi-Fi instead of 2.4GHz.
Six transmission speed
Bluetooth 5.0 because of the low-power design, the biggest drawback is that the transmission speed of about 1 ~ 3Mbps, compared to Wi-Fi (fourth generation 802.11n) can use 2.4GHz or 5GHz, 20 and 40MHz bandwidth at the fastest 72 and 150Mbps, the speed of the two has a significant gap. Therefore, the transmission speed of Bluetooth 5.0 is not suitable for film or large file data transmission.
So in this point WiFi function or win with the Bluetooth module!
From the above six points, WiFi module Bluetooth module have their own advantages. So, before choosing the right module, we still have to according to our own needs and the positioning of the product, like now there are many modules are WiFi Bluetooth at the same time, and finally choose the right module; let their products to maximize the use!
Finally, we think the smart home in the end is to choose WiFi module is good, or Bluetooth module is good, or WiFi Bluetooth both smart module?
