The Scenario:
The Baypoint Group (TBG) needs your help with a WLAN proposal. GHS is a chain of sporting good stores that cater to the sport of soccer. Because GHS has grown in popularity, it now has nine stores in the area.GHS is considering implementing a wireless technology that will link all of its stores through wireless broadband service.
