802.11n will help with overall mobile connectivity in terms of distance and speed. By being able to have that improved distance and speed capability, 802.11n is going to bring wireless technology closer to actual wire speed and wire-based reliability, which is one of the biggest lacking factors of 802.11b and 802.11g. A lot of networks -- Microsoft, NAS directories and so on --- are extremely network intensive, and if there are network interruptions, you're going to get all sorts of weird things happening. That makes having a wireless network for a LAN iffy unless the network is really built up the right way. 802.11n opens up the opportunity for a more reliable, high-speed infrastructure to support wireless LANs on clients and domains. In terms of increased use of real-time applications -- video, VoIP -- the additional speed and bandwidth of 802.11n can only help with the contention for bandwidth that can result in jitter and other quality degradation.
