Table 5.5. demonstrates the impact of Thw on response time and
battery life for a YARD Management concept, where a seal is
constantly exposed to a reader 24 hours a day.
As mentioned previously, the reader in some cases should carry out
a number of Reader Sessions to achieve the required performance.
A group of Reader Sessions is a System Session. The frequency
in which the system performs System Sessions is a System Cycle
