Wireless Sensor + Ethernet Wiring + USB connection combination without any microcontroller

Hi, In company shipping container we were using analog temperature sensor but we are now switching those sensors with a wireless temperature sensor which has long range and good battery management.

The sensor is making the wireless sensor network but for the precaution purpose, we are looking for the secondary support system also. 

whole industry is wired with an ethernet cable so I need the suggestions about how can make the data of these sensors serially at longer distances?

I need some advice in using the IC packages which will help me to travel the data at a longer distance to my gateway device by making the connection between USB and ethernet without any microcontroller any kind of suggestions will be a great help.
