distance between Access Point RLMs can be selected for
environments where stations experience slow network response times
even though the quality of radio communications is rated as excellent. The
slow response times might be experienced in areas where:
• A high number of wireless stations is located close to one another,
causing other stations to defer data transmissions.
• A number of wireless stations engaged in heavy network traffic is
causing other stations to defer data transmissions.
• The setting
/DUJH
creates overlapping radio cells, which may cause
stations in one cell to defer data transmission for stations located in the
neighboring cell.
You should only select 6PDOO distance between Radio Link Modules when
you are designing a wireless infrastructure that will include a high
concentration of Access Point RLMs: i.e. the total cost of hardware
investments is less critical than the maximum data throughput per cell.
