蓝牙是在 IEEE 802.15.1 下开发的，用于通过无线电信号提供无线通信。而UWB代表使用 BPSK 和 QPSK 调制技术的超宽带。
蓝牙和UWB最大的区别在于空中接口。在蓝牙中使用通用方法进行通信，而在 UWB 中使用脉冲指导进行通信。另一个区别是蓝牙使用2GHz(双千兆周期)载波，而超宽带使用脉冲，使用信息测量(1-40GHz)一到四十个千兆周期或很多。
我们来看看蓝牙和UWB的区别：
| S.NO | Bluetooth | UWB |
|---|---|---|
| 1. | Bluetooth has no full form. | While UWB stands for Ultra-Wide Band. |
| 2. | The frequency range supported in bluetooth vary from 2.4 GHz to 2.483 GHz. | While the frequency range supported in UWB vary from 2.4 GHz to 2.483 GHz. |
| 3. | There are seventy nine RF channels in bluetooth. | While there are 1 to 15 RF channel in UWB. |
| 4. | It uses GFSK modulation technique. | Whereas it uses BPSK and QPSK modulation techniques. |
| 5. | There is maximum of 8 cell nodes in bluetooth. | Whereas there is also maximum of 8 cell nodes in UWB. |
| 6. | Bluetooth require low bandwidth. | While it requires high bandwidth. |
| 7. | The radio signal range of bluetooth is ten meters. | Whereas in UWB this range is also ten meters. |
| 8. | Bluetooth was developed under IEEE 802.15.1. | Whereas it was developed under IEEE 802.15.3a. |
