Suppose you are installing Ubuntu on a bunch of identical computers, and you already know the answers to certain questions (what country and time zone you’re in, what keyboard you have, how the network should be configured, how you want to partition the hard disk, etc). You can “preseed” the answers to these questions in a very simple configuration file.

At the floor, there will be a live demo using Android phones, as the Full-HD Voice codec AAC-ELD has been integrated. There’s an LTE network being set up at the show specifically for this demo. Unlike in mobile communications, Full-HD Voice is already established in several VoIP, video telephony and conferencing systems. “Every day, millions of users already make Full-HD Voice calls over IP connections,” said Harald Popp, head of the department Multimedia Realtime Systems at Fraunhofer IIS, “With the introduction of LTE, now is the perfect time to introduce Full-HD Voice to mobile communications as well. Our AAC-ELD audio codec is the perfect solution for all upcoming mobile Full-HD Voice services.”

3GPP Long Term Evolution, usually referred to as LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using new modulation techniques.[1][2] The standard is developed by the 3GPP (3rd Generation Partnership Project).

Although commonly referred to as a type of 4G wireless service, LTE release 8 currently in use does not satisfy the requirements set forth by the ITU-R organization. Future releases of LTE (referred to as LTE Advanced) are expected to satisfy the requirements to be considered 4G.

ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) is an IPv6 transition mechanism meant to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network.
Unlike 6over4 (an older similar protocol using IPv4 multicast), ISATAP uses IPv4 as a virtual nonbroadcast multiple-access network (NBMA) data link layer, so that it does not require the underlying IPv4 network infrastructure to support multicast.
via ISATAP – Wikipedia, the free encyclopedia.
How ISATAP works
ISATAP defines a method for generating a link-local IPv6 address from an IPv4 address, and a mechanism to perform Neighbor Discovery on top of IPv4.
