The following are the iPad Wi-Fi specification details. The categories are:

802.11 compatibility and frequency band: 802.11ax (Wi-Fi 6 and Wi-Fi 6E), 802.11ac (Wi-Fi 5), 802.11n (Wi-Fi 4), 802.11a, 802.11b/g and 2.4 GHz or 5 GHz.
Apple platforms supporting Wi-Fi 6E can join Wi-Fi 6E networks that are discoverable on 2.4 GHz or 5 GHz channels, and on 6 GHz Preferred Scanning Channels where 6 GHz is allowed by regulatory domain.
Note: Wi‑Fi 6E isn’t available in mainland China.
Physical layer (PHY) data rate: The highest rate at which a client can transmit data over Wi-Fi.
Channel bandwidth: The maximum channel bandwidth that is supported. Beginning with 802.11n, channels can be combined to create a wider channel that allows for more data to be transmitted during a single transmission. With 802.11n for 5 GHz band, two 20 MHz channels can be combined to create a 40 MHz channel. With 802.11ac for 5 GHz band, four 20 MHz channels can be combined to create an 80 MHz channel.
MCS index: The Modulation and Coding Scheme (MCS) index defines the maximum transmission rate at which 802.11ac/n devices can communicate. 802.11ac uses Very High Throughput (VHT) and 802.11n uses High Throughput (HT) frames.
Spatial streams/SISO/MIMO: Each radio can send a specific number of independent data streams, called spatial streams, at the same time, which can increase overall throughput. Single input single output (SISO) uses a single radio and antenna and multiple input multiple output (MIMO) uses multiple radios and antennas.

The table below details the Wi-Fi specifications for these iPad Pro, iPad Air, iPad mini, and iPad models:

802.11 standard, name, frequency	Maximum PHY data rate	Maximum channel bandwidth	Maximum MCS index	Maximum spatial streams
ax@6 GHz Supported on the following models: 12.9-inch iPad Pro (6th generation) 11-inch iPad Pro (4th generation)	2400 Mbps	160 MHz	11 (HE)	2/MIMO
ax@5 GHz	1200 Mbps	80 MHz	11 (HE)	2/MIMO
ac@5 GHz	866 Mbps	80 MHz	9 (VHT)	2/MIMO
a/n@5 GHz	300 Mbps	40 MHz	7 (HT)	2/MIMO
ax@2.4 GHz	299 Mbps	20 MHz	9 (HE)	2/MIMO
b/g/n@2.4 GHz	144 Mbps	20 MHz	7 (HT)	2/MIMO

The table below details the Wi-Fi specifications for these models:

802.11 standard, name, frequency	Maximum PHY data rate	Maximum channel bandwidth	Maximum MCS index	Maximum spatial streams
ac@5 GHz	866 Mbps	80 MHz	9 (VHT)	2/MIMO
a/n@5 GHz	300 Mbps	40 MHz	7 (HT)	2/MIMO
