Rangeīluetooth typically has a smaller range than Wi-Fi. (We’re talking an estimate that’s accurate not within inches, but perhaps within dozens of feet.) 5. The proximity data provided by BLE is much more accurate than Wi-Fi, but still not very accurate either.
WIFI VS BLUETOOTH HEADSET BLUETOOTH
Both Wi-Fi and Bluetooth can provide accurate location information, although Bluetooth may be somewhat more reliable in certain instances. The right answer here will depend on the accuracy and precision required from your use case. Wi-Fi can add an additional layer of security by using a security protocol such as WEP, WPA, WPA2, and WPA3 (the latest and preferred version of WPA). However, using Wi-Fi can help if you’re concerned about sensitive data transmission. The security in Bluetooth is sufficient for most purposes, although it’s not intended to be a secure protocol in and of itself. Wi-Fi, on the other hand, is better for sending large data files, such as videos and photos. As a result, Bluetooth is typically used for transferring small chunks of data, such as the numerical values from IoT sensors. Wi-Fi has a maximum speed that is much faster than Bluetooth: at least 54 Mbps for Wi-Fi, vs.

Now that we’ve discussed the basics of both Bluetooth and Wi-Fi, let’s go over how the two technologies stack up in terms of different features. To use Wi-Fi, an IoT device needs to be close to a Wi-Fi access point (i.e.

Generally, IoT devices that use Wi-Fi are large, stationary hubs, although they can be smaller devices as well. However, in practice you also need firmware to manage the device’s Wi-Fi credentials, since Wi-Fi is a very large attack vector for malicious actors. In order to use Wi-Fi on an IoT device, you just need a microchip, which is easy and cheap to obtain. All modern computers and smartphones come with built-in Wi-Fi capability.

Wi-Fi is a wireless networking technology that uses various bands of radio waves to transmit information between devices.

Second, Bluetooth requires much less energy than Wi-Fi, so it works better for low-power IoT devices such as basic sensors. First, Bluetooth usually requires physical proximity to initiate a signal broadcast, so there is no possibility of remote attacks. There are several reasons why developers might choose to use Bluetooth instead of Wi-Fi for IoT devices. The Bluetooth protocol actually has two different versions commonly used by IoT devices that cannot directly communicate with each other: Bluetooth Classic and Bluetooth Low Energy (BLE), which is designed for devices that need to consume low amounts of power. In order to be compatible with Bluetooth, an IoT device must have a microprocessor that can handle Bluetooth, as well as a second device to pair with it. The Bluetooth standard uses UHF (ultra high frequency) radio waves between 2.400 and 2.485 GHz, which can extend a maximum of 164 feet between two devices.Įxamples of Bluetooth technology include Apple’s wireless headphones AirPods, as well as many wireless devices such as speakers, computer mice, and keyboards. Wi-Fi as it pertains to IoT.īluetooth is a wireless technology protocol that relies on physical proximity in order to manage the connections between devices, without the need for a password. In this article, we’ll discuss the question of Bluetooth vs. Both Bluetooth and Wi-Fi are commonly used for IoT devices, but there are advantages and drawbacks to both choices because they operate in different ways.
