ePix Power Mapper 3


Power Mapper

With the ePix Power Mapper, you are no longer working in the dark. This meter is specially designed to show nulls in the UHF radio field at large distances from the antenna. You will find it hard to believe how large the signal variation can be, even quite close to the antenna. The meter will show polarisation effects and destructive null cancelations, ground and water absorption. The meter relies on the power in the radio waves, so it cannot give a fails reading or have a flat battery. Almost 100% of the signal on at the antenna is shown on the meter, giving a massive 10+ meters (30+ feet) range.

Testimonial:
"The ePix Power Mapper helps get the best possible results from any reader. All readers are affected by metals and fluids. Until now, it has been impossible to visualize the RF field and how the reflections become additive or subtractive in different environments. With the ePix Power Mapper, combined with a state-of-the-art enterprise reader such as the Alien ALR-9900+, we can now evaluate a site. Then using the Alien reader's simple setting and antenna angles, we can now avoid problems before the system goes live." -- Alien Technologies

Basic instructions:
Hold the Power-Mapper between your finger and thumb then move the meter slowly around the area you want to test. In general RFID tags take about 1uW to power up, so when mapping the RF field a reading on the power-Mapper of less than 1 indicates that a standard Gen 2 tag may not be readable. Rotate the power meter 90 Degrees to measure power in the horizontal polarisation plane. Use a resistor between the two terminals to calibrate your meter for close proximity measurements.

This meter is very sensitive and is capable of showing clearly the constructive and destructive interference patterns caused by ground bounce or metal objects within the RFID field. Test circular polarised antennas for dead spots using the meter horizontally at 3 to 5 meters range the normal dead zone can be measured. An Oscilloscope can be connected across the data out terminals to show the signal modulation.

In the United States, a meter reading of 100 at three feet of range with the 12dB attenuator switched on indicates approximately 4W EIRP.
 
In Europe, a meter reading of 100 at one meter range with the 12dB attenuator switched on indicates approximately 2W ERP.

Also available from ePix ltd is the Power-Ranger. A pocket size indicator for simple quick antenna set-up and testing; five meter range. Usually left at every installation for antenna and system verification. Safety Regulations state that you should not work within 25cm of a 2W ERP transmission.

The Power Ranger can be returned to ePix Ltd for disposal. RoHs compliant. EN60950 safety compliant.

!D Gate

The !D Gate is a modern, open pedestal that is mounted on the floor. Because it is an integrated reader, both the reader and antennae are included. It supports processes like goods receiving, transition from stock room to sales floor and anti-theft (EAS). Depending on the role, the optimum RFID parameters are chosen automatically.

!D Hand 2 - RAIN RFID handheld reader

The !D Hand 2 is Nedap’s 2nd generation RAIN RFID handheld reader, especially designed for in-store retail applications. Its high reading performance in combination with its intuitive, fashionable design make it the ideal device for store staff to work with.

!D POS

The !D POS is an integrated reader to be used for reading items at the point-of-sale station. It has a small, rugged casing that can be mounted under the cash desk. The antenna only reads items on top of the reader, while ignoring items below or next to the antenna, due to the built-in shielding. It can be connected via USB or Ethernet, while the power can be supplied by a local power supply.

!D Top

The !D Top is a state-of-the-art integrated reader that can easily be mounted on the wall or to the ceiling - using almost invisible steel cables. Its elegant, compact design blends into every store, keeping the entrance of the store or the passage to the stock room wide open. At the store entrance, the !D Top can be used stand-alone as RFID-based EAS system or used as an addition to existing traditional EAS systems.
