Technical specifications
Features: a full set of wireless router features:
Support AP (wireless access point), Client (wireless client), Repeater (wireless relay), Bridge (wireless bridge), Router (wireless router) five working modesAP mode - default mode of operation. The device is a wireless access point in this mode, support plug and play, no configuration.Router mode - the device is equivalent to a wireless router, wired interface as WAN, wireless LAN. Multiple wireless clients can share a broadband line to the Internet.Repeater mode - the use of equipment, wireless relay function to achieve the wireless signal relay and amplification, and the formation of a new wireless coverage area, and ultimately to extend the scope of the coverage of the wireless network.Bridge mode - the use of equipment bridging function, first RM04 and front-end wireless network to establish a wireless connection, and then send their own wireless signal to form a new wireless coverage, can effectively solve the signal weak and signal blind spots and other wireless coverage problems.Client mode - the AP that works in this mode is a wireless client for the primary AP, which is equivalent to a wireless network card.HLK-RM04 size as shown below:
This product provides the pins shown above, as defined below:
