The Wireless Scanner is a tool that Hackers can buy for $10,000 in game. The Wireless Scanner is used to scan for money printers that can be hacked. It can be blown up like anything else, so watch out for it, you do not get a notification if it has been destroyed, so if the money printer IPs have stopped coming, then you might wanna go check on the scanner. Once you buy a Wireless Scanner place it by someones base or somewhere with printers, but be careful and don't be seen. Then when the Wireless Scanner is placed, get on a Hacking Terminal and type "scan" that will scan for money printers both nearby you, and money printers near the Wireless Scanner. To see a hacking guide, go to the GWOS page and it has detailed instructions on how to hack your first device.
