I am a student, I want to run a test for wifi and lte small cell . is anyone can help where to start?

It would be better to tell us what exactly you would like to achieve. LTE and Wi-Fi are totally different technologies. 
To start learning about wi-fi i suggest you read the respected CWNA book. After you have wrestled yourself through this you will know a lot more about Wi-Fi 

Appreciate your reply.
I had a course for Wi-Fi, and I am attending a course for LTE. I want to run a test for the coexiatence of Wi-Fi and LTE, and get the throughput for LAA and LWA and then compare them, using NS3. do you think I need test bed?

I don't think any equipment is available yet for LAA and LWA and LTE-U .. It still has to be finalized in 3GG rel 13 . 

Thanks, You are right,
But do you know how I can differentiate between uplink and downlink?
I mean I have an idea, I want to test if I send uplink using LTE and downlink using WiFi, what the throughput of the system would be.
I dont know how I can test this idea?  do you have any suggestions?

For the moment i have no idea on how to test this. You might contact vendors who are working on this. I'd say Qualcomm perhaps.
