Recent technologies of Wireless
communication
With the advancement of the technology recent
means of communication has invented for the
wireless communication. Some of these are-
•RDIF (Radio Frequency Identification)
•NFC (Near Field Communication)
•Bluetooth
•Wi-Fi direct

Details about the technologies used in the wireless network:
RFID:
•It is a Automated Data Collection technology.
•It uses radio frequency to transfer data between reader and
movable item to identify and track the object
NFC (Near field communication)
•NFC is also based on the RFID technology.
•It is a short range communication technology .
•It is generally used in mobile devices.
•Though there are certain benefits of using NFC, however the
main concern in this communication is the security issue.

Bluetooth:
•It is a wireless technology that enables of exchanging the data between
the two devices in a short distance.
•Bluetooth is managed by Bluetooth Special Interest Group.
• The IEEE standardization of the Bluetooth is IEEE 802.15.1, but it no
longer maintains the standard.
•It uses frequency hopping spread spectrum.
•It follows a packed based protocol using master/slave architecture.
Wi-Fi direct:
•It is a Wi-Fi standard that enables the connection of two devices
without any wireless access point.
•It is a single hop radio communication.
•One advantage of the Wi-Fi direct is that it can make the connection
between two devices even they are made by the different manufactures.

Possible dominant technologies in the future:
It can be assumed from the discussion that all the technologies
can become useful technology for the future but on the implementation
of a certain technology must be dependent on the requirements of the
organization.
In an organization, which is run by the local engineers, the use of
Wi-Fi direct can be useful as , the workings in the organization requires
more frequent data exchange between various devices. Those devices
can be made of different manufactures and as per advantage of the Wi-Fi
direct the , the data communication between two devices from the
different manufactures can be done without any local wireless access
point. This kind of implementation can lead the advancement of the
communication system which eventually help in the organizational
growth.
