蓝牙和 LiFi 的区别

1.蓝牙：
蓝牙是一种使用无线电波传输信息的短距离无线通信技术。它是一种高速、低功耗的通信技术，无需电缆连接即可无线连接小工具。

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。当范围扩展而无法保持连接时，它可以在短距离内很好地使设备保持连接。现在蓝牙在许多便携式电子设备中很常见，例如笔记本电脑、PDA、扬声器、智能手机和平板电脑等。蓝牙的范围和传输速度通常低于 Wi-Fi。

2. 光保真(LiFi)：
LiFi 代表光保真度。 LiFi 是一种无线通信技术，它使用光来传输数据，而不是像蓝牙那样使用无线电频率。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 提供比 WiFi 更高的速度。 LiFi 使用配备有芯片的 LiFi 灯泡，该芯片可在不知不觉中调制光以进行光学数据传输，LiFi 数据通过 LiFi 灯泡传输并由光感受器接收。它是完全联网的双向高速无线技术。当 LiFi 技术用于建筑物内外的所有灯光时，它提供的覆盖范围比单个 WiFi 路由器大。

蓝牙和 LiFi 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.
