- Analyze the transitional impact of WiFi design quality : We observe the impact of transitioning from low quality WiFi at the mobile device (Nexus S) to significantly improved WiFi with newer handset models, all the while with the campus WiFi infrastructure relatively unchanged. In contrast to our prior work4 which noted potential roadblocks for WiFi, we find in this work that device design plays a tremendous role in WiFi offloading with new handsets delivering an order of magnitude more consumption versus the Nexus S bringing performance back in line and even beyond prior results3. The potential impact of low-quality WiFi in the handset could have significant implications for bargain or low-cost cellular providers (ex. MVNOs) aiming to reduce handset costs.
