Near Field Communication Support, NFC
Support Device Smartphones Phones Technology Mobile apps applications
Smart-phones standards are defines by
the NFC, it used to established 2 way radio communications for
transmitting little amount of records for short small distance, for
example an inch or two → Like we can use this NFC for the
transactions of monetary, simplified setup and data exchanges of more
difficult communication such like Wi -Fi
Requirement of NFC is only provider and
one target. The providers generate one RF field which can provide
power to passive target. Following are the two ways, how to configure
NFC:

→ Passive communications: The
provider devices create one RF carrier field and the target devices
will answer by modulating the existing fields. With this mode, Target
devices will draw operating power from the field of provider, like as
in between the an unpowered NFC tag and smartphones. Tags can be read
only or read writable. The simulators can be emulates a target as
describe in the NFC tag emulation mode and smartposter mode section
below.
→ Active Communications:
Communication of two devices as peers as described in NFC P2P below
section, by two simulators running concurrently. Each and all
simulators alternate between acting as a providers (their own
transmitting fields generation) and a target (disabling the fields
related to it while listening).
That Simulator have three components as
follows →
→ Simulation Provider:
SimNFCProvider simulate OpenNFCProvider and the driver of device. The
related implement of NFC Providers API's, and communicate with the
another 2 NFC component in the quite same ways as OpenNFCProvider.
→ NFC Simulation GUI: The
related GUI provide a mean to simulates the peer device in one NFC
simulations:
- During Tag simulating, The reader / writer on devices, then GUI will act as a tag.
- While simulating the tag emulation on the devices, Then GUI will act as a tag reader / writer.
The GUI will also permit us to
configure NFC simulation and control in the NFC simulation.
→ Simulation Connector: The
connectors simulate the NFC connections and event between the devices
and related peer in NFC simulations. For Tag reader / writer and tags
emulations, With the help of GUI it simply connect to the simulator.
It will connect 2 simulators with each other during the simulations
of peer to peer – P2P.
