In recent years, the uses of wireless technologies (cell phones, global positioning system (gps) technology, pdas with internet access, smartphones, and tablet computers) have expanded in monumental ways. a great number of people use these technologies for personal reasons why use wireless technologies in health care

Wireless technology is the future of health care. Wireless technology in health care allows for more efficient patient care and experience. They can also be used to better understand and improve workflow in hospitals. For example, nurses are usually fast-paced and extremely busy. Florida's Hospitals Celebration Health provides and equips nurse ID badges with a radio frequency identification (RFID) that works with the hospital's wifi network. Tracking medical equipment is crucial to the hospital's patients and medical practitioners. That's why hospitals are now using a wide range of expensive, highly specialized equipment such as IV pumps, beds, wheelchairs, and canes, which are always being moved from place to place. Keeping track of all this equipment and knowing where it is and making sure it's in the right spot at all times is very difficult and time-consuming for the hospital's staff. Therefore, wireless technology is an immense help to health care.
