A typical dual band 802.11n wireless network which supports both the 2.4 GHz and 5 GHz
frequency bands simultaneously is shown in Figure 7. When the wireless router supports 5 GHz
frequency band operation, the DCX is able to a full rate high definition program
for a wireless IP
client in addition to transcoded programming content for other wireless video devices in the
home such as tablets and smartphones. This increased capability to share programming content
is due to the fact that the 5 GHz frequency band supports much greater data transfer rates and
is much less susceptible to degradation from other wireless devices in the home.
