IEEE 802.11ac is the latest WiFi standard that operates in 5GHz frequency band and promises high data rate than IEEE 802.11n. In this paper, the authors carry out experiments using commercial off-the-shelf equipment in a typical home environment and quantify the gain provided by IEEE 802.11ac compared to IEEE 802.11n. Their experimental results obtained in a typical home environment show that in 5GHz frequency band with a 2x2 MIMO configuration, IEEE 802.11ac provides much higher throughput than IEEE 802.11n. IEEE 802.11ac provides an average throughput gain of 94% and 91% at a distance of 3.6m and 8.5m from the wireless router, respectively. The authors further investigate the gain in average throughput that is provided by IEEE 802.11ac when the transmit antenna diversity on the wireless router is increased from two to three. They note that IEEE 802.11ac with a 3x2 MIMO configuration helps to combat multipath fading effect present in residential home environment and provides higher average throughput than 2x2 MIMO e.g. at a distance of 11m from the wireless router, 3x2 MIMO configuration provides a gain of 15.13% than the 2x2 MIMO configuration. The authors conclude based on their results (obtained via experiments in a typical home environment) that although IEEE 802.11ac wireless routers are more expensive than IEEE 802.11n wireless routers however, high throughput provided by IEEE 802.11ac justifies the high cost associated with its routers.

Response Consistency

Purpose Miniaturization of digital technologies has created new opportunities for remote health care and neuroscientific fieldwork. The current study assesses comparisons between in-home auditory brainstem response (ABR) recordings and recordings obtained in a traditional lab setting. Method Click-evoked and speech-evoked ABRs were recorded in 12 normal-hearing, young adult participants over three test sessions in (a) a shielded sound booth within a research lab, (b) a simulated home environment, and (c) the research lab once more. The same single-family house was used for all home testing. Results Analyses of ABR latencies, a common clinical metric, showed high repeatability between the home and lab environments across both the click-evoked and speech-evoked ABRs. Like ABR latencies, response consistency and signal-to-noise ratio (SNR) were robust both in the lab and in the home and did not show significant differences between locations, although variability between the home and lab was higher than latencies, with two participants influencing this lower repeatability between locations. Response consistency and SNR also patterned together, with a trend for higher SNRs to pair with more consistent responses in both the home and lab environments. Conclusions Our findings demonstrate the feasibility of obtaining high-quality ABR recordings within a simulated home environment that closely approximate those recorded in a more traditional recording environment. This line of work may open doors to greater accessibility to underserved clinical and research populations.
