Initially just a device. A wireless SIP phone that could make use of WiFi networks.
Increasingly a WiFi Phone is a device and a service. How much independence these phones
retain remains to be seen. Of course in one sense this is nothing new. Any SIP phone
can be used through a WiFi network provided an appropriate interface is available.
The focus of this page is self contained WiFi SIP Phones and services. This may be
important because it may help to create a business model that will drive ubiquitous WiFi access.

Unlicenced Mobile Access ( UMA ) Phones
Nokia's Take on UMA
"That's the basic idea behind UMA. It connects your mobile device to your GSM/GPRS
services through WLAN (802.11) and allows you to handle calls, send and receive messages,
check your email - basically, it lets you do what you already do with your mobile phone,
this time through a wireless broadband Internet connection. When you're not in range of
such a connection, of course, the cellular network takes over. The automatic switch from
cellular to broadband is as simple as walking in your front door - you won't even notice
ZyXEL P-2000W v.2: 802,11b/g Wireless Sip Phone
"It allows users to make or receive phone calls as long as they are in the coverage of
IEEE 802.11b or 11g wireless Access Points.
It is not only an ideal alternative for ITSPs
(IP Telephony Service Providers) to deploy their VoIP services; it can also be the wireless handset,
which is applied in corporate IP-PBX centric VoIP environment.
By configuring a remote IP address
in the built-in phone book, the Prestige 2000W provides a direct IP-to-IP call feature when there is no
intermediate SIP proxy server available in the network. The Prestige 2000W can also establish an 802.11
ad-hoc network (computer-to-computer network without Access Point), which allows users to use the handsets
as wireless intercoms. "

Unlicenced Mobile Access ( UMA ) now part of
Generic Access to A/Gb Interfaces ( 3GPP )
"Unlicensed Mobile Access (UMA) technology provides access to GSM and GPRS mobile
services over unlicensed spectrum technologies, including Bluetooth and 802.11.
By deploying UMA technology, service providers can enable subscribers to roam and
handover between cellular networks and unlicensed wireless networks..."
"...with UMA, mobile operators maintain control of their subscribers
and services when connected via Wi-Fi. With UMA, a secure, managed IP
connection is established between the mobile handset and the operator's
core network. All of an operator's mobile services (voice, data, and IMS)
are available to the subscriber when connected via Wi-Fi. In addition,
with UMA active voice calls and data sessions are automatically handed
over between networks as subscribers come in and out of range of WLANs."
The 3rd Generation Partnership Project (3GPP)
"The original scope of 3GPP was to produce globally applicable Technical
Specifications and Technical Reports for a 3rd Generation Mobile System based on
evolved GSM core networks and the radio access technologies that they support
(i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD)
and Time Division Duplex (TDD) modes). The scope was subsequently amended to include
the maintenance and development of the Global System for Mobile communication (GSM)
Technical Specifications and Technical Reports including evolved radio access technologies
(e.g. General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE))."
"Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) mobile phone technologies.
It uses W-CDMA as the underlying standard, is standardized by the 3GPP, and represents the European/Japanese answer
to the ITU IMT-2000 requirements for 3G Cellular radio systems."
FON: Funded by Google & eBay/Skype
"FON is a Global Community of people who share WiFi.
Share your WiFi broadband access at home/work and enjoy WiFi all over the world! FON: small cost, great benefit!
If you'd like to join the FON Community, register with us at www.fon.com. You can select the user profile that most suits you.
FON is now working in a Beta phase and is only available for Linus. A Linus is any user who shares his/her WiFi in exchange for
free access throughout the Community wherever there is coverage. In the future, FON will also be available for Bills.
Instead of roaming for free, Bills are users who prefer to keep a percentage of the fees that FON charges to Aliens.
And Aliens are those guys who pay to connect."

Wi-Fi & WiMax Phones in Development
SamSung: WiBro: H1000 & M8000 Mobile Phones:
"Samsung will demonstrate WiBro (Wireless Broadband; Korean brand name of Mobile WiMAX) mobile phones.
As WiBro gets prepared to be fully implemented and utilized in the market next year, Samsung will put on display both the mobile phone-typed H1000 and the PDA-typed M8000.
The H1000 is a clamshell designed phone that can be opened both horizontally and vertically with a QWERTY key pad.
It has 2.2 inch LCD screen to enhance email and internet capabilities. The H1000 also has dual cameras (2 megapixel
and VGA level) and TV Output function. The M8000 is a smart phone equipped with a QWERTY key pad for easy email usage.
Additionally, Samsung will feature a WiBro PCMCIA card that can be used in laptops and Tablet PCs.
WiBro is a homegrown South Korean technology jointly developed by Samsung Electronics and the Electronics and
Telecommunications Research Institute (ETRI) based on Intel Corp's WiMAX high-speed Internet standard.
Motorola, Intel team on mobile WiMax:
"WiMax is considered a promising next-generation wireless technology because it supports high data rates and has a
long transmission reach. The technology supports data speeds from 1 megabit per second to 5mbps, and it can be
transmitted over a 20-mile radius. This is much farther than Wi-Fi technology based on
802.11 standards, which typically transmits signals only up to 50 feet.
WiMax is also believed to be cheaper than comparable cellular technology because it requires fewer network elements.
Motorola sees WiMax as a key piece of its mobility strategy and plans to introduce an 802.16e WiMax phone in early 2007.
The company also plans to build a dual-mode phone that supports WiMax and cellular to allow people to roam in and out
of the two networks for maximum wireless coverage. Motorola already sells a dual-mode Wi-Fi and cellular phone."

Beyond WiMax. Food for Thought
xG Technology: xMax:
a new low power, long range broadband technology called xMax.
xMax is a novel modulation and encoding technology that boosts the range and power
efficiency of all wired and wireless communications. xMax is not a compression technique,
but rather a synergistic mix of two well-established communication approaches that dramatically
improves spectrum utilization.
xMax delivers broadband data rates orders of magnitude farther than other technologies
operating at the same frequency and power level. Conversely, xMax achieves equal range with
far less power, thereby improving battery life. Because product designed to operate using
xMax show improved range, significantly less infrastructure is required to cover a given service area. "

WiFi Phone Service Offerings
Skype and Vonage: thank you, and goodnight:
"3GSM It's small, it's boring and won't turn any heads - but it probably spells the end of the road for Skype,
Vonage and any other hopeful independent VoIP companies. It's Nokia's 6136 phone, which allows you to make
calls over your home or office Wi-Fi network, as well as on a regular cellular network. UMA, or unlicensed
mobile access, is the mobile operators' answer to the threat of VoIP - and now it's reality."
VON: Voice Over WiFi: A Work In Progress:
"You can buy VoFI today, for use in your home, on the road, or in your office, that’s clear. You can see it in use, in hospitals and other places.
Given the still-in-progress standards, hacks to jigger bandwidth availability, QoS, seamless roaming, and handset rollouts, it all seems still in the “needs experts” stage."
VoWLAN Business Models: How the wireless VoIP market catalyses fixed-mobile convergence:
"The study provides rigorous argument and detailed quantitative forecasts of the future of VoWLAN.
It assesses residential and corporate usage cases, both standalone and in “dual-mode” form with cellular telephony.
The report examines the role of VoWLAN in driving forward various fixed-mobile convergence (FMC) business models."
