Power over Ethernet, or PoE, is a technology that allows devices to be powered by Ethernet cables. PoE is an excellent alternative to traditional power outlets because it allows you to place devices wherever you won’t find a power outlet. PoE devices come in two different power device types: power sourcing equipment (PSE) and powered device (PD). PSE devices are responsible for providing power to PDs. 

 The standard PoE 802.3.af technology can be customized to add on R520, that is WLINK R520-P. With PoE technology, R520-P can delivers electrical power to PoE-enabled devices using a CATx network cable. WLINK R520-P is the most common type of PSE device, it allows you to quickly add PoE power to your network system. R520-P 4G LTE PoE Routers offer a simple and efficient way to power PoE devices like IP cameras, PoE access points or other Edge equipment.

 R520-P 4G router is an ideal wireless data transmission device for applications that transmit large data load because of ultimately fast transfer speed in 4G network reaching up to 150M download and up to 50M upload. VPN features also can be configured in WLINK router, allowing you to utilize virtual private network service through a 4G/3G wireless router and built for stresses and workload of a modern industrial or commercial environment.

 With dual SIM optional, R520-P series router could backup network between the two SIM cards to ensure continuous connection. The router also option with GPS capability, enable it ideal for fleet tracking or access management.
