Compared to Bluetooth, WiFi is a high-speed (transmission rate), high bandwidth wireless communication technology.īluetooth technology is commonly used in IoT product development due to its low power consumption as well as the reduced risk of remote attacks. IEEE 802.11a standard WiFi communication offers a 54 Mbps data transmission rate, whereas IEEE 802.11n gives 600 Mbps.
WiFi comes under the IEEE 802.11 network specification. WiFi offers greater bandwidth in data transfer and is faster than Bluetooth. BandwidthĮven though Bluetooth and WiFi use radio waves for data transfers over short distances without a wire connection, they are different in terms of transmission rate and bandwidth. In general, Bluetooth technology offers low bandwidth communication. BLE uses 40 channels, each with 2 MHz bandwidth. In Bluetooth low-energy, the bandwidth is double that of Bluetooth classic. Each of these channels are separated by 1 MHz, and this defines the bandwidth of the Bluetooth classic channel. Data packets are transmitted over 79 designated Bluetooth channels. Bluetooth technology uses the frequency hopping spread spectrum technique to spread data, which is transmitted as packets. While we discuss the possible transmission rates of various Bluetooth versions that transmit data within the 2.4 GHz band, we must also examine the meaning of bandwidth in Bluetooth. There are several other versions of Bluetooth available, and the table below gives their data transmission rates. Since the transmission rate is higher than that of Bluetooth classic, BLE reduces power consumption and is significant in IoT applications. The data rate is enhanced up to 24 Mbps in Bluetooth low-energy (BLE). When using frequency-shift keying modulation, the transmission rate of Bluetooth classic is about 1Mbps. With a faster transmission rate, the frequency of the intermittent transmitter turn-offs increase, resulting in reduced power consumption.Ĭonsidering the concept of transmission rates using Bluetooth as an example, we can describe this wireless technology as one with a low transmission rate. In wireless communications, the transmission rate depends on several factors: the frequency band of the technology, modulation techniques, and the complexity of the transceiver.Īs the transmission rate increases, it is possible to turn off the transmitter when not in use. The transmission rate is the metric that indicates which technology is the fastest. The transmission rate determines the speed of the communication link or channel and varies with different wireless technologies such as Bluetooth, WiFi, ZigBee, etc. It is usually expressed in baud or bits per second (bps). The transmission rate is the volume of data transmitted over a transmission channel within a specified duration of time. bandwidth requirements of an application helps designers choose between Bluetooth classic or Bluetooth low energy to best optimize the IoT system of interest. Understanding the difference between the transmission rate vs. Before deciding on whether to use Bluetooth classic or low energy, it is necessary to consider other parameters such as the transmission rate, bandwidth, and throughput. To save power, Bluetooth low energy is used in battery-operated IoT devices. In IoT devices, Bluetooth technology is used for short-range communication.
