1.蓝牙:
蓝牙是一种短程无线通信技术,它使用无线电波来传输信息。无需电缆连接即可无线连接小工具是一种高速,低功耗的通信技术。
它用于在短距离内在固定和移动设备/计算机之间交换数据。当范围扩大而无法保持连接性时,它可以在短距离内很好地使设备保持连接状态。如今,蓝牙已在许多便携式电子设备(如笔记本电脑,PDA,扬声器,智能手机和平板电脑等)中普遍使用。蓝牙的范围和传输速度通常低于Wi-Fi。
2.光线保真度(LiFi):
LiFi代表Light Fidelity。 LiFi是一种无线通信技术,它使用光而不是像蓝牙这样的射频来传输数据。意味着它利用光波来传递数据。这就是为什么它也被称为无线光网络技术。 LiFi提供的速度比WiFi高。 LiFi使用配备有芯片的LiFi灯泡,该芯片可对光进行不可见的调制,以进行光学数据传输,并且LiFi数据通过LiFi灯泡传输并由感光器接收。它是完全联网的双向高速无线技术。如果将LiFi技术用于建筑物内和建筑物周围的所有灯光,则与单个WiFi路由器相比,它可以提供更大的覆盖范围。
蓝牙和LiFi之间的区别:
S.No. | Bluetooth | LiFi |
---|---|---|
01. | Bluetooth uses radio waves to transmit data. | LiFi uses light waves to transmit data. |
02. | It does not require any LED bulbs for data transmission. But a LED can be Bluetooth enabled for communication. | It requires LiFi enabled LED bulbs for data transmission. |
03. | Frequency range of bluetooth is in between 2.4 and 2.485 GHz. | As it uses Light so Light does not require frequency. |
04. | The most common type class 2 Bluetooth can operate upto 10 m range. | Li-Fi has a range of approximately 10 meters but it depends upon LED light connection. |
05. | Bluetooth can pass through walls and any solid objects. | But LiFi can not pass through any walls or any solid objects. |
06. | Bluetooth can be availed only in a Wireless Personal Area Network (WPAN). | LiFi can be availed only upto which the LiFi LEDs are connected means wherever light is available. |
07. | It provides a standard data transfer rate of 800 Kbps. | It provides a data transfer rate of greater than 1 Gbps. |
08. | Power consumption rate of Bluetooth is low. | Power consumption rate of LiFi is medium. |
09. | Bluetooth is less secure than LiFi. | LiFi is more secure than Bluetooth. |
10. | It operates at 2.5 MHz. | It operates at visible light band. |
11. | Development started in 1998. | Development started in 2011. |
12. | Bluetooth works in less dense environment. | LiFi works in high dense environment. |
13. | Bluetooth works on the concept of Master Slave. | LiFi works on the concept of direct binary data serving. |
