This is in regards to wireless internet, so Ill assume you meant if your wireless internet will work at your school. 

If you mean your own personal wireless internet you have setup at home, then the answer is no.  The wireless connection at your home will only be sent in areas very close to your home. 

Some locations , including schools, will have wireless internet for you to use.  However, the university I went to didnt have wireless for everyone to use and we had to get our own internet connection.
But places like libraries and coffee shops may have wireless internet for you to use for free, but you would have to be in or near those locations to use their connection..

Hope this helps, if not go ahead and explain your question more..
