What is PoE sim card router?

Now we heared PoE more and more often, and the sim card router with PoE are widely used in vary kinds of M2M applications.

What is PoE on earth? Power over Ethernet (PoE) is a networking feature defined by the IEEE 802.3af and 802.3at standards. PoE lets Ethernet cables supply power to network devices over the existing data connection.

PoE-capable devices can be power sourcing equipment (PSE), powered devices (PDs). The device that transmits power is a PSE, while the device that is powered is a PD. Most PSEs are either network switches or PoE injectors intended for use with non-PoE switches. Common examples of PDs include VoIP phones, wireless access points, and IP cameras.

What can we benefit from PoE?

1)Because PoE allows you to use one cable for both power and data transmission, PoE saves you money on purchasing and running cable for networking equipment and VoIP phones.

2)PoE makes installing or expanding a network much simpler and cheaper in buildings where it is too expensive or inconvenient to install new power lines.

3)Using PoE lets you mount devices in places where it would be impractical to install power, such as drop ceilings.

4)Using PoE can reduce the number of cables and electrical outlets needed in a crowded equipment room or wiring closet.

And what is PoE+?

The latest update to PoE is the IEEE 802.3at standard, known as PoE+. The major difference between 802.3af (PoE) and 802.3at (PoE+) is that PoE+ PSEs can provide almost twice as much power over a single Ethernet cable.

PoE+ PSEs can supply power to both PoE and PoE+ PDs, but PoE PSEs can only supply power to PoE PDs. PoE+ PDs require more power than PoE PSEs can provide.

Can I mix PoE and non-PoE sim card router in my network?

PoE devices can be mixed in a network with non-PoE devices, but non-PoE devices cannot provide power for PDs or be powered by PSEs. The non-PoE devices must have a separate source of power.

Can industrial 4g router support PoE?

Considering PoE’s advantages, some sim card router support POE. Often the PoE sim card router router connects with POE Switch and IP Cameras.

Some excellent PoE industrial 4g routers are available in market.

Accompany with IoT’s development, there comes out many PoE industrial routers. You can choose E-Lins Technology’s indoor or outdoor PoE sim card router, which have been widely used worldwide. For more information, you can check with E-Lins Technology Co., Limited
