You are right
wireless communication has evolved greatly and today we can no longer do with them. Businesses have improved so much as well as the health sectors.

Wireless communication has helped to improve the way we communicate with our friends, families, and loved ones. And technology is aiming at changing our lives in more ways than we can imagine.
