Mobile VoIP
VoIP Mobile requires a mobile handset that supports, at minimum, high speed IP
communications. Most commonly this is using Voice over Wi-Fi or VoWi-Fi, but the
same protocols (typically SIP or Jabber) can be used over any broadband IP-capable
wireless network connection such as the various 3G standards, EVDO rev A (which is
synchronously high speed - both high speed up and down), HSDPA or potentially WiMAX.
VoIP Mobile will require a compromise between economy and mobility. For example,
Voice over Wi-Fi offers free service but is only available within the coverage area of a
Wi-Fi Access Point. High speed services from mobile operators using EVDO rev A or
HSPDA will probably have better audio quality and capabilities for metropolitan-wide
coverage including fast handoffs among mobile base stations, yet it will cost more than
the typical Wi-Fi-based VoIP service.
VoIP Mobile will become an important service in the coming years as device
manufacturers exploit more powerful processors and less costly memory to meet user
needs for ever-more 'power in their pocket'. Smartphones in mid-2006 are capable of
sending and receiving email, browsing the web (albeit at low rates) and in some cases
allowing a user to watch TV.
The challenge for the mobile operator industry is to deliver the benefits and innovations of
IP without losing control of the network service. Users like the Internet to be free and high
speed without extra charges for visiting specific sites. Such a service challenges the most
valuable service in the telecommunications industry - voice - and adversely (or favorably,
depending on your views) affects the pace of innovation in the global communications
industry.
Mobile VoIP relies on two main technologies:
UMA - the Unlicensed Mobile Access Generic Access Network, designed to allow
VoIP to run over the GSM cellular backbone SIP - the standard used by most VoIP
services, and now being implemented on mobile handsets
Recent developments VoIP Mobile industry is estimated to grow to 12 Billion Dollars by
2010 in Europe alone. Four technologies are required for mobile VoIP functionality: a
device, client software, a wireless network and a VoIP service.
Throughout the early 2000s, Hewlett-Packard, Symbol Technologies and others have
been innovators in Wi-Fi-based hand-held devices, as Personal digital assistant or
hand-held computers for warehousing and other applications. As successive generations
of these devices gained in processing power and battery life, their potential use as a
platform for mobile VoIP became practical. Using Microsoft Windows CE operating
systems, in the summer of 2005 companies delivered practical client software to run on
these class of Wi-Fi only, Windows-based PDAs.
In the summer of 2006 SIP (Session Initiation Protocol) stack was introduced and a VoIP
client in the E-series dual-mode Wi-Fi handsets (Nokia E60, Nokia E61, Nokia E70).
From a Wi-Fi network perspective there are several innovations, imbedded in the most
current vendor Wi-Fi networking equipment for the enterprise and municipal service
provider, that makes them particularly powerful in a mobile VoIP context. These
innovations include support for strong encryption making the conversation in a Wi-Fi
context quite private (IEEE_802.11i), support for Quality of Service for real-time services
such as mobile VoIP (see IEEE_802.11e) and in some cases support for wireless access
point to access point call hand-off.
VoIP server vendors, upon which VoIP service providers create the service have
announced support, as early as January 2006 for dual-mode phones and the VoIP
client from FirstHand Technologies, known as Mobile Console. Enterprise IP PBX
vendors have developed, tested and announced capabilities for mobile VoIP users
interacting with their business IP-based phone systems. Sylantro Systems has recently
experienced high turnover, including the loss of CTO, CMO, CFO, CEO in the last few
months. Broadsoft continues to be gaining in customers, partners and revenue, and is
has indicated their intent to go public.
Fixed mobile convergence brings the mobile VoIP element together with the public mobile
phone service in a way that enables seamless roaming across these devices. Standards
and alliances have been developed and technologies have been demonstrated as early
as December 2005. Cisco and FirstHand Technologies demonstrated a Wi-Fi to GSM
handoff in San Jose, December 5, 2005.
WiFiMobile, founded in 2002 were one of the first mobile VoIP providers with their own
self developed VoIP client compatible with all Nokia E and Nseries smartphones.
Recently T-Mobile blocked the access to pure mobile VoIP numbers, which were issued
by Truphone for the first time. The issue was widely discussed in the press and although
Truphone won an injunction, the case is still in the courts while T-Mobile pay only a
nominal termination fee.
