Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The majority of wireless local area network (WLAN) technologies, including the wireless fidelity (WiFi) standard IEEE 802.11, is characterized by the use of a single shared channel. The use of a single channel is very different from most wireless cellular technologies [for example, Global System for Mobile communications (GSM)], where communications simultaneously occur in independent wireless channels deployed in different time slots and frequency bands. Indeed, the use of a shared channel necessitates the specification of some access rules to guarantee that terminals transmit in different time intervals without collision. These rules are defined in the medium access control (MAC) layer, which represents a fundamental part of every WLAN standard. © 2009 IEEE.
