The SXT R is an integrated low-cost 10.5dBi LTE antenna WITHOUT LTE modem (free miniPCI-e slot). In the case, if for any reason you don't want to use one of our own LTE modems, you can simply buy the SXT R and install the modem of your choice. The SXT R is a device for remote locations that are within cellular network coverage. However, due to it’s professional LTE chip design and high gain antenna, it can provide connectivity for your building even where cell phones can’t. The unit is equipped with two Ethernet ports (the second port has PoE-out functionality), so you can use it to power up another device. The unit includes a 24 V power supply, but can support full range of 12-57 V and 18-57 V with PoE-Out and is 802.3af/at compliant.
