cell phone signal booster , basements, brick walls?

how can I put a homemade cell signal booster together for my basement apt.? what will be needed for the frequencies adjustment? Can I use an old rooter or ?

DIY cell phone booster isn't going to be doable. You would need some vary expensive and specialized equipment to help in designing and building the transmitter and receiver. Your would be better off talking to your cell carrier about buying a signal booster or getting an in home antenna. The latter typically comes with added fees and is typically just a receiver that connects through your internet/phone line back to the cell company. Rather than trying to transmit through walls and what not back to the nearest tower.
