Interop Las Vegas

At this year 2006 Interop held in Las Vegas on May 1-4, some of the big discussions in and around the show was deploying and managing VoIP and collaborative systems to lay the groundwork for IP networks to carry future generations of voice and other real-time traffic.

Also at Interop this year was a panel discussion on "Advanced Wireless Technologies" in the Wireless and Mobility portion of the Conference. Krishna Yarlagadda, CEO for HelloSoft, was asked to join this panel discussion for his background knowledge and expertise; that explored the latest advances in radio technology and the applications driving them. The panel was led by Craig Mathias a Principal with Farpoint Group. The other members on the panel were: Noam Geri, VP Marketing and Business Development, Amimon, Sue Hares, CTO, Nexthop, Pat Calhoun, CTO, Wireless Business Unit, Cisco, Krishna Yarlagadda, CEO, HelloSoft, and David Borison, Director, Product Management, Airgo Networks, Inc.

Voice Path Architecture In Mobile Handsets

 
1. Introduction

 
Wireless, Mobile, and Internet technologies have revolutionized the way in which people communicate with each other. Today, anyone who wishes to make a voice call is presented with a multitude of options like Cellular, VoIP, VoWLAN etc., to select from. One can pick and choose any service based on quality and cost considerations. 

While these technologies are widely accepted and are well established, the 'Convergence' of these technologies seems to be the next big step in the communications industry. As the service providers gear up to provide the next generation converged solutions, more and more complexity is being added to the mobile handsets which will now have to support multiple technologies without compromising on quality, performance, and cost.

This article focuses on some system level aspects related to supporting a voice call in mobile handsets, which support multiple technologies.

 
2. Architecture

 
The diagram below shows the basic architecture and the entities involved in a voice call. The block diagram shows various components in the mobile station, some implemented in hardware, some in the operating system and drivers, and some implemented as user programs of the operating system. 

The mobile supports Generic Access (or GA) (ETSI TS 143 318) or IMS VCC (or Voice Call Continuity) that can provide seamless handover of voice calls between GERAN network and WLAN/VoIP network.
 

 
3. GSM Voice Path

 
In GSM, the voice path involves capturing the audio packets from the audio codec, processing it through the speech codecs of GSM, and providing it to the GSM voice path interface that routes the voice through the GERAN interface. 

On the transmit side, the audio codec collects voice samples from the microphone, and converts them into digital samples at the PCM rate (i.e., 1 sample for every 127 microseconds). The GSM speech codec processes these samples and encodes the voice data for transmission over GERAN air interface. The voice path controller interfaces the output of the speech codec to the GSM PHY/RF driver, which sends it out over the air interface

On the receive side, the application picks up voice data from the GSM physical/RF layer driver, and sends it to the GSM Speech Codec. After decoding, the speech codec sends this data to the audio codec driver, which is forwarded to the audio codec, which in-turn plays the voice on the speaker.

 
4. WLAN Voice Path

In WLAN, the voice path involves capturing the audio packets from the audio codec, processing through VoIP speech codecs, and sending them to the VoIP voice path interface that routes the voice through the WLAN interface. 

The audio codec collects voice samples from the microphone, and converts them into digital samples at the PCM rate (i.e., 1 sample for every 127 microseconds). The speech codec processes these samples, and encodes the voice data for transmission over the WLAN interface. 

On the receive side, the packets from WLAN are received as RTP packets from a UDP port, and routed via appropriate VoIP packet adaptation block modules. The voice path controller routes the output of these modules to the speech codecs of VoIP, and the decoded packets are played out on the audio interface via the audio codec. 

The voice path controller interfaces the output of the speech codec to the VoIP packet adaptation block, which involves RTP/RTCP, Packet Loss Concealment (PLC) unit, Jitter buffer and other voice processing modules.

In case of generic access, the speech codecs are a subset of GSM codecs, and the voice packets are passed through a secure IPSEC tunnel established with the network.

Generic Access capability and IMS VCC capability enable seamless handshake between WLAN and GERAN networks. In such cases, the voice path controller, in coordination with the signaling stacks can control handshake between both networks.

802.16e revenues to reach $53B by 2011

 
Follow the money. WiMAX services will generate $53 billion in mobile revenue in 2011 and will generate $65 billion in mobile capital expenditures between now and then. These are the conclusions of a new report from TelecomView. The report analyzes the market for 3G and WiMAX in mobile networks with forecasts through 2011, along with a business case which illustrates the benefits of WiMAX architecture in high-speed mobile networks.

"We forecast that WiMAX will account for at least half of the broadband mobile service revenues in North America", said TelecomView's Ian Cox, a co-author of this report. "While we also believe that it will be a key technology in Asia, we think that it will lag behind 3G technologies in Europe given the investment being made in 3G and HSDPA." The report's other author, Bob Larribeau, said, "Our business case shows that the ROI for WiMAX is two to three times better than 3G technologies... Trials underway at Sprint, Korea Telecom and NTT DoCoMo are a good indication that carriers are quite interested in the benefits that WiMAX brings."

Wi-Fi Alliance Talks Dual-Mode - By James Alan Miller

 
April 18, 2006 - The Wi-Fi Alliance is partnering with the Cellular Telecommunications & Internet Association (CTIA) to develop and promote certification programs for overlapping aspects of converged phones, such as Radio Frequency (RF) performance and the handover between cellular and Wi-Fi networks. The two groups announced this collaboration at the giant CTIA 2006 show, where a number of fixed-mobile convergence/dual-mode/Wi-Fi-cellular technologies and solutions were shown off and demonstrated less than two weeks ago. Twenty dual-mode handsets are already in the works for this year alone, for example.

PDAStreet recently got the chance to speak with Wi-Fi Alliance managing director Frank Hanzlik about his organization's role in the partnership and Wi-Fi/Cellular convergence in general.

Hanzlik started off by saying "the Wi-Fi Alliance/CTIA coming together is a big deal".

"It really shows we kind of burned a few at the table. There was some concern in the past about Wi-Fi and 3G, as to how well they worked together or didn't," Hanzlik explained to PDASteeet. "But today, there are a lot more people feeling good about how complimentary these technologies really are," he continued. More...

VoIP Business Equipment Market to Hit $5.5 Billion by 2007 - By Diane DiPrima

 
Tuesday, 28 March 2006 - Enterprise adoption of VoIP is expected to grow this year as the business voice over IP equipment market reaches $5.5 billion, according to a new report from Juniper Research. This growth will be unsustainable, however; the report projects that after next year the hardware and software market for business VoIP will drop, declining $2.5 billion before 2010.

Increased connectivity due to the development of telecommunications within China's expanding economy will contribute to the market's growth, the report notes. Additionally, VoIP equipment will be purchased to replace a large number of aging telecom systems that were bought in 2000. Once the Chinese telecom market cools and a majority of businesses complete their hardware replacements, equipment sales numbers will level off as revenues decrease due to competitive pricing from manufacturers located in the Far East and India.

Juniper Research's report also projects the IP PBX market will rise above $1.6 billion next year with North America and China making up the biggest markets. An earlier report from the Dell'Oro Group forecasts 17.2 million IP PBX lines will ship in 2007. (See IP PBX Lines to Maintain Climb, Dell'Oro Reports.) More...
