Extending your wireless network access

The HPE Aruba Networking 501 Wireless Client Bridge enables you to easily integrate devices with no native wireless support into a wireless LAN (WLAN). It provides strong enterprise-class layered security features, including an IEEE 802.1X supplicant, to protect the network from intrusions.

The 501 Wireless Client Bridge can bridge up to 15 Ethernet client devices running a legacy networking protocol to the WLAN – extending wireless network access to a wide range of protocols. An integrated serial to TCP/IP converter enables a RS-232 asynchronous terminal device to communicate with a compatible station on the network. Hardwareaccelerated encryption provides higher performance when using WPA2/AES security.

This bridge provides the benefits of wireless mobility for devices like electronic cash registers, scales, servers, printers, medical equipment and other devices. It can be deployed in any location where a WLAN signal is available – saving the time and expense of installing Ethernet cables for wired network access.

The 501 Wireless Client Bridge integrates into the Aruba Mobile First solution architecture and is interoperable with the IEEE 802.11a/b/g/n/ac wireless network infrastructure in a multi-vendor environment.
