YealinkWF50 Dual-Band Wireless USB Adapter for Compatible IP Phones

YealinkWF50 Dual-Band Wireless USB Adapter
The YealinkWF50 is a compact USB wireless adapter designed to provide network connectivity for compatible IP phones. It supports dual-band wireless operation across the 2.4 GHz and 5 GHz frequency ranges, offering flexibility when connecting compatible communication equipment to an available wireless network.
Dual-band connectivity supports different network environments. The 2.4 GHz band supports transmission rates up to 150 Mbps, while the 5 GHz band supports rates up to 433 Mbps under the specified wireless standards. Actual performance depends on the selected frequency, network configuration, signal conditions, and the capabilities of the connected network equipment.
The adapter uses a USB 2.0 interface and an integrated antenna. Its compact construction measures approximately 52 × 27 × 8 mm, making it suitable for use as a small wireless connectivity accessory rather than a standalone networking device. It is designed to work with supported phone models and should be checked against the phone's firmware requirements before installation.
Compatibility includes selected T-series phone models, including T27G, T41S, T42S, T46S, T48S, T42U, T43U, T44U, T46U, T48U, T52S, T54S, and T53. The manufacturer specifies firmware requirements for supported models, so compatibility should be confirmed for the exact phone model and software version. Not every phone with a USB port is necessarily compatible with this adapter.
The adapter supports multiple wireless security configurations, including WEP, WPA/WPA2, WPA-PSK/WPA2-PSK, and WPA2-Enterprise. Select a security configuration supported by both the wireless network and the connected device. Network security also depends on the access point configuration and the security settings in use.
The plug-in design provides a straightforward way to add wireless connectivity to a supported phone without routing an Ethernet cable directly to that device. It can be useful in office environments, reception areas, and workspaces where a compatible phone needs wireless network access and a suitable wired connection is unavailable.
The adapter operates at 5.0 V DC ±5% and is specified for operating temperatures from 32°F to 104°F. The listed operating humidity range is 10% to 90%, non-condensing. These specifications describe the operating conditions provided in the manufacturer's datasheet.
The package contents are listed as one WF50 adapter and one user guide. A separate power adapter is not listed as an included component. The product is a wireless connectivity accessory and does not function as a standalone telephone or wireless router.
Before purchasing, verify the exact phone model, firmware version, available USB interface, and wireless network requirements. This helps ensure that the adapter is appropriate for the intended installation.
