1. 802.16:
802.16 是 IEEE 标准,它定义了微波接入 (WiMAX) 技术产品的无线互操作性。它涵盖了所有WiMAX系列产品。它针对 50 公里进行了优化。它在整个覆盖区域提供服务以实现连续连接。这个 802.16 标准从可用性的角度提供了更多的可扩展性。

2. 802.11:
802.11 是定义无线局域网 (WLAN) 或 WiFi 的 IEEE 标准。它涵盖了所有WLAN系列产品。它针对近 100 米进行了优化。它不提供整个覆盖区域的服务以实现连续连接。从可用性的角度来看,此 802.11 标准提供的可扩展性较差。

802.16 和 802.11 之间的区别:

S.No. 802.16 802.11
01. IEEE 802.16 standard defines WiMAX. IEEE 802.11 standard defines WLAN or WiFi.
02. It is designed for long distance/wide area. It is designed for limited area.
03. It provides a coverage range of 7 km to 50 km. It provides a coverage range of 30 m to 100m.
04. 802.16 standard is used for outdoor usage. 802.11 standard is used for indoor usage.
05. It operates on frequencies of 2.4 GHz, 5 GHz. It operates on frequencies of 2.5 GHz, 3.5 GHz, 5.8GHz.
06. Standard variants of 802.16 are 802.16a, 802.16d, 802.16e, 802.16m etc. Standard variants of 802.11 are 802.11a, 11b, 11g, 11n, 11ac, 11ad etc.
07. It provides a data rate of 100 Mbps in a 20 MHz channel. It provides a data rate of  54 Mbps in 20 MHz channel.
08. Large number of customers are connected to this as it covers a wide area. Limited number of customers/devices are connected which are with in the limited range.
09. For encryption purpose it uses Data Encryption Standard with Advanced Encryption Standard. For encryption purpose it uses Rivest Cipher 4.
10. Different QoS options are available like UGS, rtPS, nrtPS, BE, etc It does not provide any QoS but Supported in IEEE 802.11e.
11. Bandwidths varies dynamically as per user requirement from 1.5 to 28 MHz. Bandwidth variants are 20 MHz, 40MHz, 80MHz and 160 MHz.
