Differentiated Services architecture (Diffserv) is the most widely deployed IP QOS architecture and hence most router QOS implementations are optimized for Diffserv deployments.
Figure 7 shows the cdf of the doses over a time frame of one hour for traditional and optimized deployment for three uplink usages (0%, 10%, and 100% of the time), for the LTE data scenario.
Figure 4 shows the cdf of the doses over a time frame of one hour for the traditional and optimized deployment for three uplink usages (0%, 10%, and 100% of the time), now for a WiFi throughput of 18 Mbps.
Figure 5 shows the cdf of the doses over a time frame of one hour for the traditional and optimized deployment for three uplink usages (0%, 10%, and 100% of the time) for the UMTS voice call scenario, where the mobile device is held to the right side of the head.
Figure 3 shows the cumulative distribution function (cdf) of the whole-body doses over a time frame of one hour for the traditional and optimized deployment for three uplink usages (0%, 10%, and 100% of the time) for WiFi with a downlink throughput of 54 Mbps.
For the optimized deployment, UL becomes dominant for usages around 1000 s (see logscale in Figure 8).
For 100% uplink usage, the total dose for the optimized deployment (2.75 · 10−5 J/kg) is a factor 19 smaller than the total dose for the traditional deployment without UL usage (5.21 · 10−4 J/kg).
For the optimized deployment, the UL dose is 2.7 times higher.
For the optimized deployment, locations close to the FBS have lower downlink doses, thanks to the lower FBS EIRP, and locations far from the FBS have lower uplink doses thanks to the presence of the additional FBS. Figure 6 clearly shows that the high doses (lighter colors) are lowered for the optimized deployment.
Due to the lack of power control, uplink usages of only a few seconds suffice to make the uplink dose higher than the downlink dose, limiting the reductions of the optimized deployment for longer uplink usages.
Figure 5 and Table 2 show that even when calling the entire time (100% UL usage), the whole-body total dose for the optimized deployment (3.46 · 10−6 J/kg) still remains below the whole-body total dose for the traditional deployment without UL usage (3.72 · 10−6 J/kg).
