Wi-Fi 6 AX6600 wireless netwrok, Bluetooth

The AP661 is designed to transmit Wi-Fi 6 wireless networks, supporting IEEE 802.11 b/g/n/ax protocols in the 2.4 GHz band and IEEE 802.11 a/n/ac/ax protocols in the 5 GHz band. The device can simultaneously conduct 3 radio transmissions: 2.4 GHz 2x2 MIMO, 5 GHz 2x2 MIMO, and 5 GHz 4x4 MIMO - 2 + 2 + 4. Consequently, the maximum theoretical throughput is 574 Mb/s in 2.4 GHz, 1201 Mb/s in 5 GHz 2x2 MIMO, and 4804 Mb/s in 5 GHz 4x4 MIMO. Such high speed is particularly suitable for locations intended for multiple users simultaneously. The AP661 will provide sufficient throughput in situations where standard APs would not be able to deliver transmissions to clients at a fast enough speed.

The access point also utilizes several additional features that positively impact network quality. MU-MIMO allows simultaneous transmission and reception of data from multiple clients, eliminating data queuing. Beamforming shapes the beam to improve connection with devices at the edge of the coverage area, while TWT (Target Wake Time) conserves energy by waking connected devices only when a transmission is initiated.

Additionally, the device supports Bluetooth transmission (BLE 5.2), which you can utilize for remote management, localization, or IoT applications, among others.

2.5G Ethernet port, 1G Ethernet port, USB port, PoE / DC in

The offered product is equipped with one 2.5G Ethernet port (10/100/1000/2500 Mb/s) and one gigabit Ethernet port (10/100/1000 Mb/s). The 2.5G port also serves as the input for IEEE 802.3at PoE power, and power can also be supplied through a standard DC socket (12 V). The maximum power consumption, excluding USB, is 21.2 W.

The manufacturer has included a USB port with the intention of using it to connect an external modem for IoT support, such as ZigBee or RFID.

Smart antennas

The access point features Smart antennas, consisting of multiple elements that can work independently. Depending on the requirements, antenna elements can modify the shape of the main beam to provide the best coverage to connected clients. The device adapts to radio conditions and provides significantly better signal coverage than APs equipped with standard omnidirectional antennas. The gain is 4 dBi in the 2.4 GHz band and 5 dBi in the 5 GHz band.

Up to 1536 clients

The Huawei AP661 can support up to 1536 clients (512 per radio) and is designed for very challenging locations, such as exhibition halls or concert venues. The manufacturer suggests that the access point should ideally serve a maximum of 300 clients simultaneously. In this configuration, it can deliver approximately 22 Mb/s throughput to each client, which is sufficient for standard internet usage. The system supports load balancing and smart roaming, so if one access point becomes overloaded, users are switched to others.

The DFA (Dynamic Frequency Allocation) algorithm is used for automatically detecting wireless channel usage and identifying overlapping transmissions. In the case of multiple access points, they operate in a way to avoid interfering with each other. Additionally, technologies such as EDCA (Enhanced Distributed Channel Access) and airtime scheduling allow for scheduling the channel utilization by client devices, ensuring equal access to the network for each of them.

A significant advantage of the system based on eKitEngine APs is the optimization of network utilization by client devices. Clients with low signal strength or connection speed are automatically disconnected to improve overall transmission quality. Additionally, the AP661 features a 5G-prior function - client devices are primarily connected in the 5 GHz band to provide them with the best possible throughput. This significantly reduces the load and interference in the 2.4 GHz band.

Advanced wireless system

The offered product is designed to operate in a large wireless system composed of multiple access points. Such a network can cover even very large areas, depending on the number of devices used. The system supports data roaming, allowing users to be automatically switched between individual access points without losing connection.

Huawei's solutions offer a wide range of features related to bandwidth control, improving transmission quality, and security. For user authentication, you can utilize methods such as 802.1x, MAC address, or captive portal. An advanced management and monitoring system will allow you to reduce the time spent on network administration, for example, through automatic detection and recognition of various types of errors.

Four operating modes

Access points can operate in four modes:

• Fat AP - the access point operates independently, and configuring and managing it resembles the process for standard wireless routers. It's suitable for small networks where you use only one AP.
• Leader AP - It allows configuring the device as a "leader," thereby taking on the role of a controller in the network. You can connect other access points to the device in Leader AP mode to create an expanded system. This mode is best suited for small networks, such as offices or restaurants, and helps reduce costs associated with purchasing additional controllers.
• Cloud AP -  in this mode, the access point can be managed from a cloud-based platform. This platform significantly simplifies monitoring and conducting initial configurations, eliminating the need for additional management devices.
• Fit AP - this is the basic mode of operation in which the access point connects to a controller.

Multiple uses

The Huawei AP661 is best suited for locations where you expect a large number of simultaneous users, such as concert halls or exhibition halls. Its high throughput capability ensures that even with numerous clients, the device can deliver each transmission at sufficient speed. AP661 supports numerous modern features and can handle very challenging locations where the performance of other access points may be insufficient.
