What’s Your RF IQ?

Feb. 9, 2006
Think you’re in the know about RFID? Let’s see. Take our quiz, provided by the Computing Technology Industry Association.

The following quiz comes courtesy of CompTIA (the Computing Technology Industry Association, www.comptia.org), which offers RFID courses and certification. 

# 1 – The three types of RFID tags are:

  1. Ultra low frequency, low frequency and ultra high frequency (UHF).

  2. Real Time Locating System (RTLS), active and passive.

  3. Active, battery assisted active and passive.

  4. Active, passive, and semi-active.

# 2 – When assisting with a site analysis for a passive high frequency (HF) smart shelf system, which of the following should have the LEAST affect upon design consideration?

  1. Shelves made of metal

  2. Tagging multiple items

  3. Tagging materials that are RF absorbent

  4. Tagging materials that are made of metal.

# 3 – Lower frequency (LF) radio waves travel:

  1. Farther and penetrate solid substances more effectively.

  2. Less distance and have poor penetration on any solid substance.

  3. Farther but do not penetrate solid substances.

  4. Less distance but are highly effective on penetrating metal.

# 4 – A systems architect is required to configure an active RFID system composed of interrogators placed to ensure coverage for all the RFID-tagged assets in a staging area. If the interrogators are placed too close together, this will create:

  1. An effective use of the real estate.

  2. A pre-positioning of extra interrogators should one become inoperable.

  3. Over interrogation of the tagged assets and unnecessary communication to and from the network.

  4. A redundant interrogation system necessary to assure all of the tagged assets have been read and reported via the network to the server.

# 5 – Placement of a passive ultra high frequency (UHF) tag on the bottom of a metal container loaded on a pallet will cause which of the following read results?

  1. The tag will only be read if the bottom of the container is oriented to the antenna.

  2. The tag can only be read by a hand-held interrogator.

  3. The tag will be read regardless of orientation to the antenna.

  4. The tag can be read by a dock door portal interrogator.
