Now-a-days we are living in a technical era where almost all electrical products are functioning wirelessly. There are different types of protocol used for wireless communication. In this paper I am going describe about some wireless protocols use all over the world. At first we have to know what protocol is. And why it is important for communication pattern. Then I tell about drawbacks and finally there will be my assumption about different protocols.

A protocol is a set of rules or agreed upon guidelines for communication. When communicating it is important to agree on how to do so. If one party speaks French and one German the communications will most likely fail. If they both agree on a single language communications will work. For this reason there must have some rules and policies. In brief those are called protocols.

On the Internet the set of communications protocols used is called TCP/IP. TCP/IP is actually a collection of various protocols that each has their own special function or purpose. These protocols have been established by international standards bodies and are used in almost all platforms and around the globe to ensure that all devices on the Internet can communicate successfully.

IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6, 5 and 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments. These standards provide the basis for wireless network products using the Wi-Fi brand.

The most prevalent is 802.11b. Equipment using 802.11b is comparatively inexpensive. The 802.11b wireless communication standard operates in the unregulated 2.4 GHz frequency range. Unfortunately, so do many other devices such as cordless phones and baby monitors which...
