RFID Site Survey

SATCOM has all the expertise, experience and T & M instruments required to perform a RFID site survey to identify optimal locations for the RFID tags on the products, as well as the optimal locations for readers so the RFID processes work satisfactorily at customerís premises.

In an indoor environment, the RF propagation is uncertain (typical propagation models are empirically generated) to a large extent. This is due to multi-path scattering. Such uncertainty coupled with obvious ďnullĒ patterns seen in commercial tags leads to a lot of heartburn in the customerís mind. It has been observed many a times that large scale RFID deployment in an enterprise, in spite of its greater value, has been scrapped because of the failure of the system integrators to grasp the finer nuances of physical medium. To overcome this problem, RFID Site Survey is required.

An RFID site survey identifies optimal locations for the RFID tags on the products, as well as the optimal locations for readers so the RFID processes work satisfactorily at customerís premises. The objective of an RFID site survey is to gather enough information and data to determine the number and placement of your work points that will provide the total coverage required. Coverage required generally means the support of a minimum data rate in a given area.
