Long Range Access Control Readers Tutorial

Author: Brian Rhodes, Published on Nov 10, 2017

One of the classic challenges for access control are parking lots and garages, where the user's credential is far from the reader. With modern access systems, the basic methods of increasing the read distance mean using special readers, credentials, or a combination of the two.

In this note, we look at the options for reading access credentials long distances apart (enhancing readers or credentials). We also cover the importance of physically designing reading points and discuss using different frequencies to gain range (UHF/Microwaves). Finally, we contrast option costs, and list their relative weaknesses compared to standard card readers.

Inside we address these aspects and more:

  • Are Boosted Cards or Long Range Readers Better?
  • How Specific Project Requirement Impact Choices
  • Credentials Often Determine Range
  • Overview of Long-Range UHF/Microwave Formats
  • Uncommon, But Effective Cellphone Dialers
  • A Comparison Table Contrasting Options
