Mobile Communications Over IP
MoIP, or mobile communications over Internet Protocol, is the mobilization of peer-to-peer communications including chat and talk using Internet Protocol via standard mobile communications applications including 3G, GPRS, Wi-Fi as well as WiMax. Unlike mobile VoIP, MoIP is not a VoIP program made accessible from mobile phones or a switchboard application using VoIP in the background. It is rather a native mobile application on users’ handsets and used to conduct talk and chat over the internet connection as its primary channel. How MoIP (mobile) works MoIP applications typically work without any proprietary hardware, are enhanced with real-time contact availability (presence) and save the users money by utilizing free Wi-Fi internet access or fixed internet data plans instead of GSM The Global System for Mobile Communications (GSM) is a family of standards to describe the protocols for second-generation (2G) digital cellular networks, as used by mobile devices such as mobi ...

Mobile VoIP
Mobile VoIP or simply mVoIP is an extension of mobility to a voice over IP network. Two types of communication are generally supported: cordless telephones using DECT or PCS protocols for short range or campus communications where all base stations are linked into the same LAN, and wider area communications using 3G, 4G, or 5G protocols. There are several methodologies that allow a mobile handset to be integrated into a VoIP network. One implementation turns the mobile device into a standard SIP client, which then uses a data network to send and receive SIP messaging, and to send and receive RTP for the voice path. This methodology of turning a mobile handset into a standard SIP client requires that the mobile handset support, at minimum, high speed IP communications. In this application, standard VoIP protocols (typically SIP) are used over any broadband IP-capable wireless network connection such as EVDO rev A (which is symmetrical high speed — both high speed up and dow ...

Modem Over VoIP
Modem over VoIP (sometimes abbreviated as ''MoIP'') is the use of voice over IP (VoIP) to carry analog modem signals, which are then in turn used to carry a two-way digital data link. G.711 passthrough Since most VoIP codecs are designed only to carry speech signals, successful modem-over-VoIP operation generally requires the use of G.711 coding on the VoIP audio link, emulating the channel capabilities of a digital PSTN connection. ITU-T V.152 describes one way of implementing G.711 passthrough. G.711 uses 8 bits per sample, either μ-law and A-law encoded, at a sample rate of 8 kHz, and signals carried over G.711 have historically been associated with a maximum practical modem speed of 56 kbps, based on the ITU-T V.92 standard. This use of G.711 coding is sometimes called 'fax pass-through' as it enables analog fax Fax (short for facsimile), sometimes called telecopying or telefax (short for telefacsimile), is the telephonic transmission of scanned printed material (bo ...

Professional Video Over IP
Professional video over IP systems use some existing standard video codec to reduce the program material to a bitstream (e.g., an MPEG transport stream), and then use an Internet Protocol (IP) network to carry that bitstream encapsulated in a stream of IP packets. This is typically accomplished using some variant of the RTP protocol. Carrying professional video over IP networks has special challenges compared to most non-time-critical IP traffic. Many of these problems are similar to those encountered in voice over IP, but to more stringent engineering requirements. In particular, there are very strict quality of service requirements that must be fulfilled for use in professional broadcast environments. Packet loss Since even well-engineered IP networks tend to have a small residual packet loss rate caused by low-probability statistical congestion events and amplification of bit errors in the underlying hardware, most professional solutions use some kind of forward error corr ...
