Routers can operate in two frequency bands - 2.4 GHz and 5 GHz. The 2.4 GHz frequency is most often used to connect smartphones and office equipment. The USB WIFI camera ap module provides a more stable connection.
It is useful when working with video - for example, for wirelessly connecting a TV or set-top box. Sometimes it becomes necessary to connect the device via 5 GHz, but the ap module only allows connection to 2.4 GHz: in such cases, an external Wi-Fi ap module is used.
The maximum possible speed of data exchange between the router and devices (PCs, laptops, smartphones, and others) depends on it. Now used:
There is backward compatibility between these standards: devices with an outdated standard can connect to a more modern USB WIFI camera ap module, but the speed will correspond to the old standard, not the new one.
Moreover, if you have a more modern, high-speed router and an older laptop that doesn't support the new standard's maximum speed, then an external Wi-Fi ap module may be useful.
External ap modules come in several form factors.
There are three models in this format.
The first one is ESP8266 wifi module. It supports wireless data transmission at 2.4 GHz via WIFI standard IEEE 802.11 b/g/n at a maximum speed of 150 Mb/s and has a USB 2.0 connection interface.
Moreover, two more models are ESP8266 wifi module and SKW100. USB WIFI camera ap module supports wireless data transmission at a frequency of 2.4 / 5 GHz via WIFI standard IEEE 802.11 a / b / g / n / ac at a maximum speed of 867 Mb / s, USB 3.0 connection interface.
All models have a USB 2.0 connection interface.
The ap module supports wireless data transmission at a frequency of 2.4 GHz via WIFI standard IEEE 802.11 b / g / n at a maximum speed of 150 Mb / s.
USB WIFI camera ap module operates at a maximum speed of 300 Mb/s and support 2.4 GHz wireless data transmission over the IEEE 802.11 b/g/n WIFI standard.
The highest speed is 433 Mb/s. This speed possesses by the ESP8266 wifi module models, which support wireless data transmission at a frequency of 2.4 / 5 GHz via WIFI standard IEEE 802.11 a / b / g / n / ac.
Moreover, both compact ap modules have similar features. ESP8266 wifi module support wireless data transmission at 2.4 GHz via WIFI standard IEEE 802.11 b/g/n at a maximum speed of 150 Mb/s and have a USB 2.0 connection interface.
The next two models’ places on a table and have antennas. Models connect to the computer via a cable.

This is a device for connecting to a wireless network in a specific frequency range. Its main purpose is to receive / transmit a block of data transmitted over the network in packet mode.
Moreover, to catch and transmit a signal, the device equips with an antenna - external or internal. Each device has software. You also need to install the correct firmware (driver).
Now I’ll tell you more simply what a USB WIFI camera ap module is. Routers, smartphones, laptops, tablets, TVs have an integrated module. It acts as a receiver (it picks up a signal from the router) and / or a transmitter (it can distribute a signal as an access point). This I think everyone knows.
All equipment that works with Wi-Fi wireless technology equips with a network ap module!
If a PC or any other device does not have a network module, we can purchase separately. Moreover, an external (portable) Wi-Fi ap module plugs into a USB port. Works the same as built-in - receives and transmits a radio signal.
There is another type of network device for connecting to a wireless network - a PCI ap module. It comes inside the system unit, connected to the motherboard using a PCI slot. As a rule, such devices are equipped with an external antenna, which is installed outside the "system unit". Why do you need such a Wi-Fi ap module? It also receives a wireless signal and connects to the network.
On laptops, it can be turned on with “hot keys” -fn+ one of the function keys (most often with the Wi-Fi icon). Moreover, another way is through the Device Manager. We go to the "Network ap modules" section, find the USB WIFI camera ap module, press RMB, select "Enable device". We connect to the network.
We connect to the USB port, install the drivers. To connect, you can use the Utility that is installed with the software, or through the Windows system tray (wireless connection icon).
PCI ap module
We connect the device itself to the motherboard, install the antennas. Further, as with the external one, we install the drivers, we connect through the Utility.
