Hi, firstly sorry for my english.

I would like to learn about which specificarion of mobile wifi router's determines receiving signal distances. I will use mobile wifi router at ship. I dont need too much output wifi signal distance because i am using router in small room but receiving signal is more important for me because sometimes our ship is very far from land and we can not get any signal. I hope you understand my problem. I need more receiving signal for my mobile wifi router, speed or something else is not important for me . I choose m 7350 model to use but i dont know anything about receiving signal property. Can i use some signal booster for that model. Please enlighten me for my problem. Thank you in advence.
