NFC and Bluetooth

Scope of topic

There is a huge scope of this research. This research allows deep understanding of the world most commonly used communication technologies. It provides the depth comparison of Near Field Communication (NFC) and Bluetooth technology and also defines the areas in which these technologies are preferably used and what their limitations in the field are. As this research study also includes the way in which these technologies can be implemented therefore it is also very helpful in implementing these technologies in various field and applications. This research is also very helpful for various mobile manufacturing companies so that they can understand and use the most effective technology for their upcoming mobile phone models.

Basics of Near Field Communication (NFC)

Near Field communication (NFC) is considered as short range technology as it is designed for performing wireless communication at ultra-short range. This technology uses help of magnetic field induction to provide, enable and also for maintaining the connectivity between the connected devices, only when these devices comes in physical contact with each other or within a small few centimeters range. NFC in today world is emerging as an efficient and effective technology for performing communication between different consumer electronic devices. The most similar application of NFC is RFID in which it is used is network topologies which are done from the convergence process of contactless identification (Rackley, 2008, P 22, 24-26). The basic aims of NFC is to ensure simple and efficient peer to peer communication or networking through automatic configuration and connection.

NFC is compatible with RFID. The major differences present between communication of standard RF wireless module and NFC are that in RFID the signal travels from transmitter to receiver over a long range of area while in NFC the range is very limited and short and communication only takes place when physical contact between devices are made. Standard communication of RFID are like Wi-Fi systems which is considered as far field communication in which range depends on the hurdles present between transmitter and receiver and also on antenna size. On the other side, NFC, does not depend on antenna, it is depend on the magnetic field to connect other device with first device. In summarized way, NFC relies on direct magnetic or electrostatic coupling between components within the communicating devices rather than free space propagation of radio waves (Palenchar, 2012, P 2-3).

The benefits of NFC

When using NFC technology for communication, we can achieve following benefits:

Due to short range communication, there is no concept of buying license for frequency band as it is very short range communication and can be used any frequency band.

The power consumption of NFC is very reasonable and limited as it is short range and does not requires high ...
