Cisco + Android + VoIP 2.0 = Unified Communications?

Cisco to Combine Google’s Android, UC and Enterprise 2.0 by ZDNet’s Dave Greenfield — I met with Cisco’s distinguished engineer Cullen Jennings for unified communications last week, where he showed me a new concept demo that lays out where Cisco is going with mobility and Unified Communications (UC). Think Google’s Android pro ject for the enterprise and you wouldn’t be that far off. Amongst other things, the demo shows […] how the company hopes to become a major player in the enteprise application space. […]

Good Voice vs. Bad Voice and Customer Ditching

What happens when voice calls break down into static or loud noises? Users care - of course. Users ditch the service provider with poor quality. Ditech Networks watched users fleeing poor service providers with bad voice and moving to service providers with better voice quality:

1. Ambient Noise–affected up to half of all calls in some regions.
2. Acoustic echo from headset or phone affected 11% of calls and results from calls being made in such small spaces as automobiles.
3. Voice level mismatch, where volume is set too high or too low causing one caller to shout while another is whispering, happens in 28% of all calls.

Ditech Networks, a provider of voice quality solutions globally, conducted an audit to measure the level of mobile phone voice quality that currently exists, and found a whopping 39% of all calls were deemed “unacceptable” or likely to cause churn to another carrier. In mature markets, 23% of all calls fell below industry minimums and in rapid growth markets, 59% of calls fell into the same category.
[…] The cost of the churn is estimated at $23.6 billion.

– “Why more than 182,420 mobile subscribers a day left service providers”, Carolyn Mathas, Mobile Handset DesignLine

Unified communications means different handheld devices will support voice. In this environment, each handheld guarantees optimal voice quality across all conditions. This means careful engineering for FMC products!

Open Access for Handsets Wins Victory

Ever wonder why your cell phone can’t do certain things: like send instant messages? Or synchronize your calendar with the calendar on another device? Or upload a new photo to your favorite online photo site?

Much of this has to do with “open access,” or lack of open access. Cellular service providers use competitive practices to “lock out” application providers from allowing the phone to do what users want to do - this ensures the cellular provider makes more $ from the user.

The market is changing with the new rules from the FCC, which is opening up new frequencies (which will be used in next generation cellular handsets) with a special rule: companies who use the frequency must allow competing devices to also use the frequency. This is known as open access.

With open access, customers will have the ability to choose the device which does the things they want to do — unimpeded by a provider’s service-blocking. This ultimately forces providers to open up their own systems, under pressure of market competition — no one wants to buy a device that is “blocked from access” compared to a device which allows for “open access.”

The following article from Wired explains the technical details: FCC Auction Ensures Open Access — If in Name Only, By Bryan Gardiner

Open-access proponents let out a collective sigh of relief in late January when an anonymous bidder with a fat purse exceeded the $4.6 billion reserve price for the nationwide C-block of 700-MHz spectrum.

The still-sealed $4.71 billion bid, which came during the auction’s 17th round, means that the Federal Communications Commission’s open-access stipulations will be all but ensured when a future network based on C-block spectrum is built out. Google and other companies fought hard for these open-access requirements in the months leading up to the auction.

“I think this is ultimately a good sign,” said Gregory Attiyeh, managing director of FTI Consulting. “Even though we won’t see an open-access network for a while, it reinforces the fact that open access is the thing of the future: It gets the ball rolling.”

The open-access conditions attached to the national C-block of spectrum ostensibly mean that the eventual winner of the licenses must allow all compatible devices and applications to run on the network. That’s in marked contrast to the way most cellular networks work today, where the owners of the spectrum — the carriers — have virtually total control over the handsets and applications that use their networks.

Open-access proponents see the change as necessary to encourage innovation and competition in a wireless-devices industry that has long been stifled by U.S. carriers’ unwillingness to relinquish control.

The end result is features like VCC, FMC, mCue, VoIP, can compete within the marketplace. The technology has an available spectrum for users to communicate with each other in the ways they want to communicate: anywhere, at any time, in any medium (video, voice, text, photos, files, VoIP..).

Open Handset Alliance Phone

Next generation handset designs as proposed by the Open Handset Alliance and Google Android intend to take full advantage of the open access rules.

iPhone May Become Open to New Applications Soon

The iPhone may become more open soon.

iPod Touch

How open the environment is depends on the support they provide in the new release, as discussed in the Forbes article below:

Macworld may be over, but for a group of developers the most important Apple news has yet to be unveiled: the much-anticipated iPhone software development kit (SDK).
Developers say they can’t wait to get their hands on the SDK, which is expected to be released in late February and will allow third-party developers to create native applications for Apple’s (nasdaq: AAPL - news - people ) iPhone.
http://www.forbes.com/technology/2008/01/26/iphone-apple-developers-tech-wire-cx_ew_0128iphone.html

This follows the trend of communication products allowing third-party applications and developers, sometimes with low barrier to entry to the third-parties. Google Android, Nokia, Symbian, and now Apple have available environments for creating new applications. This provides new opportunities for unified communications products like mCUE which have, in the era of Web 2.0, come from unlikely sources and small startup companies (such as digg.com, facebook.com, skype.com, and others).

Google CEO Eric Schmidt Comments on the Next Generation Unified Web

According to Google CEO Eric Schmidt, in the video below, the future of the Web, and communications, uses many applications which fit together using internet data stored on multiple servers in many sources (”in the cloud”).

(Paraphrased) “Applications are small, data is in the cloud, applications can run on any device, PC or mobile phone, applications are very fast, and customizable. Applications are distributed by social networks, email, forwarded between users, virally. This is a very different method than implemented previously… very different from the mainframe era.”

The hallmark of unified communications and fixed-mobile convergence is running communications applications on any device, in any location, and using services from any source. For this to occur, the user needs application frameworks smart enough to simplify the multiple protocol problem which now faces most application developers. There are many protocols involved in communicating between anyone and anywhere. Multi-session and Multi-protocol frameworks are a way to make this happen.

Accessible From Anywhere

FMC and synergy means network access (browse Google Maps) and voice communications (check voice mail and send texts) while mobile, from a unified communications device.

Google is leading the way with mobile initiatives, like the Google mobile phone platform (”android“). The vision is to allow accessibility, anywhere, to Google’s services. Using voice communications technology, such as FMC technology, becomes seamless (the network is always connected) for other application providers.

Technology insiders call this technologyIMS-SIP/VCC for Seamless Mobility Between VoWiFi and Cellular Networks“. More easily said, it means: voice, video, text, email, and more, accessible from anywhere.What other technologies also pave the way? Add a comment, let us know.

CEO專訪-D2 Technologies執行長王爾仁博士 從寬頻、Mobile到IP communication 由VoIP到Mobile Unified Communication 全新溝通世

陳昌博/台北

D2 Technologies執行長王爾仁博士表示,無法創造新營收加上維修成本日高,傳統電話系統10年內就會消失,特別是在已開發國家如台灣、日本及韓 國,carriers從傳統電話獲得的收入愈來愈少,而另一方面,寬頻通訊與應用的業務則不斷提高。現已成為通訊技術主流的VoIP,在未來五年,可預見 大幅成長的主要推力將來自傳統電信業者。

以日本來說,目前VoIP的普及率(即寬頻到戶再接上VoIP)已達50%,美國的Cable Modem附帶VoIP,加上光纖到戶部份,約有500萬至1,000萬VoIP用戶。王爾仁說,對傳統電信業者而言,會維修舊電話系統的人愈來愈少,而 且電話放在網路上,會產生很多服務與應用,如留言會轉成簡訊到手機上,也就是說,VoIP不擔心電話接不到。還有,在IP網路上,距離是沒有價值的,所謂 長途電話也失去意義。

所以,無論就減少成本、增加競爭及營收,傳統電信業者都即將會力推VoIP。另外,VoIP最終會取代傳統電話系統的原因還源自於大量IP communication裝置的上市,如從CPE終端用戶設備/產品到IP phone再到行動多節點IP手持式裝置。

從 學者投入產業,堪稱是VoIP商業應用技術領域先驅之一的王爾仁,於80年代即成立第一家研發DSP O/S公司,後來被TI併購。接著於1993年成立 D2 Technologies,歷經Virata和GlobespanVirata併購,D2 Technologies 於2003年Spin-off後重新投入VoIP發展。

由於當時VoIP的局端業務成長有限,但用戶端還有很 多商機,特別是台灣是CPE的ODM/OEM設計製造重鎮,可以很快將D2 Technologies獨具、以embedded軟體取代一顆VoIP之硬體DSP技術特性與應用做充份展現。因此,D2 Technologies旋即於2004年來台設立辦事處。

Embedded VoIP軟體可以讓ODM/OEM製造商得以運用先進的通訊硬體平台與IC,快速且具成本效益地發展廣泛的VoIP通訊裝置,包括從局端設備到無線IP電 話。D2 Technologies的embedded軟體已為下一代匯流多節點IP手持裝置與設備提供解決方案。

回想4年前,D2 Technologies向CPE客戶推介其embedded vPort軟體時,要費力解釋此軟體取代硬體DSP的功能。到現在,由於IC速度愈來愈快,且許多公司基於硬體成本,客戶已經不要DSP硬體了。

王 爾仁指出,軟體DSP只要幾週就可以建置到產品中,但硬體的DSP卻要幾個月。CPE客戶端會要求晶片廠如TI、Broadcom及NXP等,提供 embedded軟體建置,但一家CPE客戶若用不同大廠的solutions,由於各自的embedded軟體不同,還要費時調整。所以業界就出現要求 晶片大廠的晶片內建D2 Technologies軟體的趨勢,未來更可能成為一種產業標準。如歐洲大廠Thomson日前宣佈,在其DSL晶片中embedded D2的VoIP軟體。

談到D2 Technologies市場佈局,王爾仁說,將與寬頻服務商如電信業者合作,支援VoIP發展,藉由傳統電信業者亟欲將不利情勢扭轉為有利情勢的力道, 與電信業者共同佈局行動通訊技術及應用。檢視行動通訊的全球化發展,是從歐洲帶頭,再來是亞洲、然後美國。D2 Technologies在Mobile的佈局會先從與手機製造商及較小的電信業者合作開始,如美國的Sprint,未來再順勢與大型電信業者合作。

台灣合作夥伴包括寬頻VoIP整合製造商如Alpha Network、Tecom、Accton、SerComm、E28等,下一階段將與英華達及E28合作雙頻手機,及與E-LAN合作的IP phone。

在 與晶片商的合作部份,D2 Technologies的解決方案可減少使用昂貴的數位訊號處理晶片DSP。藉由單CPU晶片整合方案,在低功耗與高效能的表現上,已優於多核心及多晶 片的網路語音產品。D2 Technologies已和Infineon、TI、NXP、Cavium Networks、Thomson擁有長久之合作關係。

藉由將軟體層獨立於底層的硬體架構,D2 Technologies能讓產品製造商專注於產品與品牌經營,並兼顧軟體、作業系統及晶片元件。面對各種設計需求,D2 Technologies的高度模組化方案可相容於各種處理器、硬體或作業系統,提供先進的功能和通話品質。目前D2 Technologies的軟體,在市場上已達每月處理億萬分鐘語音流量於各種不同類型的語音產品。

王爾仁表示,Voice只是VoIP 中的一個功能之一,所謂IP Communication的涵蓋範圍其實相當廣。我們現在對電話號碼的概念在未來也將改變,將來只要一個ID number,就能與外界溝通連絡,且與所在的位址無關,而不同時候的身份,只要log-in,就可以access。這種溝通的改變,在5至10年之後, 就會愈來愈明顯。

從寬頻、Mobile到IP Communication,由VoIP一直演化到Mobile Unified Communication的溝通新世界,將在2008年中初現雛形。王爾仁說,D2 Technologies對Mobile Unified Communication的解決方案,會將IM、Email、Text Message、Voice Mail、VoIP等功能整合進來。為增加研發能量,D2 Technologies除在美國波士頓總部設有Mobile研發中心、新竹辦公室負責CPE應用技術研發,在中國亦投資兩家公司軟體開發公司。未來並將 規畫台灣的管理人才去負責中國的研發團隊。

關於D2 Technologies的vPort產品系列中,vPort是一套完整的VoIP軟體解決方案。vPort以先進的SoftDSP軟體模組取代硬體 DSP,並可支援三方通話會議功能,以及call forward,call transfer,call waiting、caller ID等電話的運用。vPort以D2的vTSP為模組,含相關語音的Algorithm,語音處理 (echo cancellation、voice compression、DTMF generation等),以及語音通訊協定 (SIP、XMPP、IMS-SIP, VCC等)及時封包、緩衝器(RTP、Jitter Buffer)、telephony drivers及全雙工免提通話等功能,並藉由VoIP reference application layer能與多種網路裝置做連結。

D2的vPort能夠取代硬體DSP的效能,將DSP 移植在OS上,提供客戶更經濟,更有效率簡便的SOC,除能達到與傳統電信業者的通話品質標準99.999%一樣優異的通話標準之外,更能滿足Time- to-Market 的要求。目前已有vPort 1.3 Release,根據產品路線規劃,vPort將陸續會有更多功能如 IMS-Client、Unified Communication整合於vPort 系列。

The Unified Communications Future

How has unified communications changed your business?

“Avaya began rolling out unified communications to our most mobile employees – executives and sales – in 2003. The solutions enabled a single interface from which staff members could access voice and email, check calendars, launch calls and conference calls and more through voice commands from any device. They were also equipped with our ground-breaking Extension to Cellular application that simultaneously bridged calls made to their business extensions to their cell phones. This provided “single number access” to the user, with greater security and privacy for those who regularly used cell phones for business. We found the time saved on an average amounted to 15 days per year per user. Since then, we have continued to lead the market in innovative, unified communications applications that enable seamless access to converged real-time and non-real-time communications delivered over any device, any network to users in any location.” — Stuart Wells, President, Global Communications Solutions at Avaya

Unified communications technologies such as Voice Call Continuity in mobile handsets allows dual-mode phones to take advantage of local data networks. This allows convergence between cellular networks and local data networks and is the primary first step for FMC.

FMC Mobile Phones Due to Arrive “Soon”

Mobile phones which include FMC technology are due to arrive soon. Of course we are all eagerly anticipating this technology, which innovates past voice vs. data vs. accessibility complaints.

“It’s apparent that in order for FMC to really take off, there needs to exist a reasonable variety of handsets that provide the functionality and user experience that we’ve all come to know and love.” — FMC technologist

FMC requires only a few items to hit the marketplace in force:

  • An open mobile handset platform, for third party application development
  • A service provider which supports open access to the third party applications or integrated applications, with an upgraded network
  • Users who request– or, demand– the convergent features (such as, the freedom to roam seamlessly between service platforms such as the ability to send voice instant messages to corporate-level coworkers from a personal mobile phone while laying on a beach in Santa Barbara)

“Soon” depends on only these factors.

Infonetics: 80% of Providers to Offer FMC by April ‘08

An Infonetics report, “Service Provider Plans for Next Gen Voice & IMS,” based on formal interviews conducted by senior analysts with 24 North American, European, Asia Pacific, and Latin American-Caribbean service providers, shows over two-thirds of responding service providers plan to offer fixed-mobile convergence (FMC) services within 8 months.

Primary reasons for providers to adopt VoIP are reducing operating costs and overhead, growing revenue, and adding more profitable services. These features are enabled by increasing broadband penetration and the latest generation of voice technology.

The latest generation of voice technology includes softDSP voice engines for VoIP and VCC such as those found in currently shipping products by D2 Technologies and others. Offering FMC means enabling mobile phones to communicate seamlessly according to the goals of unified communications.

Dual Mode (Cellular/ VoIP over Wi-Fi) Mobile Handsets to Drive to $82B by 2012

According to a new report by Juniper Research, worldwide VoIP over Wi-Fi equipment revenues are expected to reach over $82bn by 2012 with North America leading the market at $35bn in revenues, EMEA (Europe, Middle East & Africa) with $23bn and Asia Pacific with $21bn.

Report Author, Basharat Hamid Ashai, says that “the dual mode handset market will pick up much faster in the coming years than the single mode Wi-Fi handset sector. The handset market is moving to a stage where no one wants to carry two or three devices in their pocket, so the ability to have a single device for all calls is a compelling proposition. Most single mode VoIP over Wi-Fi handset manufactures are actively either designing or planning to ship dual mode phones”.

Further details from the report include:

1.      Dual Mode Mobile Handsets (Cellular/VoIP over Wi-Fi ) will dominate this market generating almost $68bn in revenues by 2012 out of a total market of $82bn.   Note: These handsets will be driven by technology such as Voice Call Continuity (VCC) and IMS-SIP/VCC for Seamless Mobility Between VoWiFi and Cellular Networks.

2.      Single Mode VoIP over Wi-Fi Handsets will continue to see a conservative uptake primarily due to high pricing – resulting in revenues of only $1.5bn by 2012.

3.      Enterprise Access Points (supporting VoIP) will generate over $5bn by 2012.  Note: These devices will be powered by software and hardware similar to the Integrated Designs for VoIP-Enabled Quadruple Play Devices.

4.      Enterprise WLAN Switch/Mobility Controllers (supporting VoIP) to reach almost $8bn by 2012.  Note: High bandwidth switch designs incorporate VoIP often by using softDSP technology in multiprocessor designs.

The technology notes above illustate the ready-to-design availability of technologies to fit the FMC feature set.  VoIP over WiFi and VoIP over WiMax will continue to make news in 2007 and will reach market in 2008.
