They then analyze how the remaining major cost components, switching and transmission for both types of networks and interconnecting with the switched circuit network for the IP-based networks, change with the change in technology.

Freed from these obligations, telcos could deploy these resources to higher value services, including expanding the reach of their IP-based networks.

FORBES: It's Time to Modernize Communications Policy

IP-based networks cannot guarantee instantaneous communication, so a substantial amount of buffering (several seconds) was used to smooth out any hiccups.

Chip vendors will be building more device chips and cell site radio chips, infrastructure companies are selling more cell site equipment, and since WiMAX and LTE are both IP-based networks, network back-ends will be converted from traditional switches to routers so there are opportunities for companies that make routers.

Their conclusion is that the switching and transmission costs for IP-based telephone networks are much lower than for switched circuit telephone networks.

CNN: IP telephony is the "in" thing these days, but should it be?

Further, since 4G is an IP-based technology, back-end systems will be upgraded to IP-capable networks and this will provide opportunities for Cisco and other companies in the IP router and infrastructure business.
