On the sales floor, the wireless communication service allows a clerk to check inventory for a customer or promptly call the manager. When holding an even or exhibition, or when changing the sales floor layout, the wireless service requires no cable laying or transfer, so telephone installation and removal are simple.

At hotels and resorts, the wireless communication service can be used between the front desk and the rest of the complex and for communications and instructions between staff members of an event in the complex. Assign each security guard a handy phone set, and you can realize more systematic reporting and higher mobility, as well as higher security in the event of an emergency.
