When designing a WLAN network to support both voice and context-aware services, there are certain design principles that should be followed to ensure optimal network performance and user experience.
Option A suggests that a voice and context-aware site survey can be conducted together, and both deployment recommendations can be implemented. However, this option also suggests that APs that are not serving clients should be in monitor mode, which may not be ideal for a WLAN network supporting voice and context-aware services. Therefore, option A may not be the best choice.
Option B recommends deploying more APs for context-aware services due to the requirement for perimeter coverage and coverage in all four corners of a floor. However, voice deployment recommendations should be prioritized due to the mission-critical nature of voice traffic. This option may be suitable for WLAN networks where voice is the primary service, and context-aware services are secondary.
Option C suggests that both voice and context-aware services can be surveyed together, but voice deployment recommendations should take precedence over context-aware deployment recommendations. This is because the context-aware survey may recommend too many APs, which could introduce too much co-channel interference, negatively affecting voice quality. Therefore, this option may be suitable for WLAN networks where voice is the primary service, and context-aware services are secondary.
Option D suggests that both voice and context-aware services can be surveyed together, but context-aware deployment recommendations should take precedence over voice deployment recommendations. This is because context-aware services require at least four APs to hear clients or tags at -75 dBm, whereas an AP can provide adequate coverage to voice clients with acceptable signal-to-noise ratio (SNR). Therefore, this option may be suitable for WLAN networks where context-aware services are the primary service, and voice is secondary.
Option E suggests that both voice and context-aware services can be surveyed together, but voice deployment recommendations should take precedence over context-aware deployment recommendations. This is because context-aware surveys may recommend too many APs, and APs need to be in local mode because APs in monitor mode spend too much time listening and not enough time transmitting, which can negatively impact voice quality. This option may be suitable for WLAN networks where voice is the primary service, and context-aware services are secondary.
In summary, the best set of design principles to follow when designing a WLAN network to support both voice and context-aware services depend on the primary service of the WLAN network. If voice is the primary service, then options B, C, or E may be suitable. However, if context-aware services are the primary service, then option D may be the best choice.
