White-Fi和Wi-Fi HaLow是低于1 GHz的标准，旨在支持IoT应用程序的要求。两种WiFi标准都旨在提供远距离和低功率运行。
1.白色保真
White-fi是用于表示Wi-Fi的IEEE 802.11af版本的通用名称。 White-Fi通常被称为超级Wi-Fi或空白Wi-Fi。它的设计方式是在非常高的频段和超高频段的下端使用电视频道的未使用空间或空白空间。它非常适合远程设备。 White-Fi的主要缺点之一是，它需要特定于频段的昂贵硬件组件。
2. Wi-Fi HaLow
IoT传感器需要以较低的数据速率进行远程数据传输。引入Wi-Fi HaLow可以满足此类要求。它是通用名称，用于表示Wi-Fi的IEEE 802.11ah版本。 Wi-Fi HaLow能够穿透墙壁和物体。它可以被认为是突发和短数据的理想候选者。该标准的应用很少，包括数字医疗市场，智慧城市和智慧家庭等。
White-Fi和Wi-Fi HaLow之间的区别：
| S.No | White-Fi | Wi-Fi HaLow |
|---|---|---|
| 1. | IEEE 802.11af version of Wi-Fi | IEEE 802.11ah version of Wi-Fi |
| 2. | It was released in 2014. | It was released in 2016. |
| 3. | Operates in the 54 to 790 MHz frequency band. | Operates in the 900 MHz frequency band |
| 4. | It works with channels having bandwidths of 6, 7, and 8 MHz. | It works with channels having bandwidths of 1, 2, 4, 8, and 16 MHz. |
| 5. | The maximum data rate is 26.7 Mbps. | The data rate of 100 kb/s are possible in a 1-MHz channel and up to several hundred Mb/s are achievable in a 16-MHz channel. |
| 6. | It promises a coverage range greater than 1 km. | It promises a coverage range upto 1 km. |
| 7. | Operates in the TV white spaces | Transmits in the unlicensed frequency band at 900 MHz |
| 8. | With a low transmit power of just 100 mW for mobile user stations and 4 W for base stations or access points, there’s an opportunity to use battery-operated equipment communicating over White-Fi. | Power Consumption is low. |
