Alcatel has joined the push-to-talk (PTT) fray with the launch of its own PTT solution.

Alcatel says its version can run on a wide variety of handsets already commercialized and equipped with this function, thanks to client software enabling interoperability with most of the devices on the market. The system is based on SIP (Session Initiation Protocol) for signalling and RTP (Real Time Transport) for voice broadcasting, following the early specifications of the OMA (Open Mobile Alliance) and uses the capabilities of the IMS (IP Multimedia Sub-system) as specified by 3GPP.
Using Alcatel's Proxy Platform software architecture, the Push To Talk server runs on Intel Xeon processor servers, using Linux OS.
"Push-To-Talk is a key service and a turning point in the mobile operators data strategy," Jean-Michel Cornille, President of Alcatel's mobile solutions activities, said. "The application gives operators an immediate revenue opportunity."

Motorola has opened its European  Innovation Centre in Swindon, in the UK. The centre is designed to demonstrate mobile communications technologies to the end user and to assist customers when choosing technologies appropriate to their subscriber needs.

The newest technology to be showcased at the innovation centre is Motorola's High Speed Downlink Packet Access (HSDPA) for UMTS. 
Other technologies that Motorola will be showcasing in the Swindon Innovation Centre include Push-to-Talk over Cellular (PoC), 3G including videos calls, video downloads and streaming as well as simultaneous voice and data calls, Public WLAN, private WLAN and Voice over WLAN demonstrations, and the Motorola SoftSwitch.
"For a mobile operator planning its business strategy, the ability to test and compare real system performance in a live working environment is crucial," said Margaret Rice-Jones, corporate vice president, Motorola.

Self-adapting networks are the only way forward as demand grows for wireless networking,and for voice over wireless (VoWLAN), say established companies and start-ups alike.

The IEEE's proposed 802.11e standard for quality of service (QoS), due later this year, addresses voice and data applications contending for bandwidth, but the problem of too many wireless access points (APs) sharing the same radio space may be a tougher one to crack.
So far, suppliers have looked to centralised security switches as a partial solution, says Isabelle Guis, a WLAN product marketing manager at Nortel. These allow existing APs to be connected to the LAN, creating a centrally managed hybrid wired/wireless network.
Now though they are coming up with adaptive networks, which study the world around them and react accordingly. "Adaptive networks are plug and play so they are more efficient," Guis says, noting that Nortel partnered with Airespace to gain adaptive WLAN technology.
"Both adaptive and hybrid support voice, but an adaptive network has better overall QoS. For example, if an AP in a meeting room is overloaded, the system can recognise that and move users to another AP. And where before we could detect a rogue AP, now we can prevent the client from connecting to it."
Start-up company Bandspeed has also spotted the crowding problem and come up with an ingenious solution: APs that transmit on different channels in different directions, intelligently changing channels and adjusting radio power for the best coverage and least interference.
"There are capacity issues as more users come on board," says Blaine Kohl, Bandspeed's marketing VP. "Today the AP is a hub that everyone shares. Most say you can get six to 10 clients per AP, then you can have three APs per space.
She adds that VoWLAN will make the problems worse, as it will increase the number of WLAN clients and also because phones tend to move around more than PCs.
"People are struggling with RF manageability --- they quickly find out it's not scaleable, as with more than three APs in one space they will hear each other. In large public spaces like airports, it is already becoming a problem."

Symbol Technologies has introduced the Mobility Services Suite (MSS), to help enterprises decrease the time it takes to deploy a mobile infrastructure. The Symbol Mobility Services Suite consists of three components: Mobility Services Platform (MSP); Mobility Services Agents (MSAs); and MSS Studio.

The MSP is an appliance that provides control of deployments by communicating with MSAs resident on all Symbol mobile devices and systems. This enables mobile device and wireless network management and monitoring, including discovery, remote control, configuration, provisioning and troubleshooting.
The MSS Studio enables application developers to create new and extend existing back-end applications to a large variety of mobile computing devices over WLAN, GPRS and other networks. MSS Studio is built on standards including J2EE and Web services. Future versions will include SDKs for Microsoft Visual Studio .NET and .NET Compact Framework.  
The Mobility Services Suite was designed to be extensible to accommodate emerging mobility services, including voice over IP, security and RFID.
The MSS is also designed to  integrate with existing enterprise network management solutions, such as IBM Tivoli, HP OpenView and CA Unicenter, supporting interaction through standard networking protocols.

GRIC Communications is adding support for GPRS in the forthcoming  version of its Mobile Office solution.

GRIC Mobile Office users who subscribe to a GPRS service will be able to wirelessly access their corporate networks and applications, anywhere there is a GPRS signal. End users can also exchange SMS messages with other devices on the GPRS network. GRIC already offers WLAN, Ethernet or dial-up access choices to subscribers.
"GRIC is delivering on our vision of providing secure, reliable, and cost-effective access to corporate networks, and applications using all popular access methods including wireless," said Rob Fuggetta, senior vice president of worldwide marketing for GRIC.

Processor and technology developer TTP Communications said it was encouraged by the outlook for the year ahead, despite reporting a pre-tax loss of £2.7million for 2003/4, compared to a 36.6million profit in 2002/03.

The company said a profitable second quarter gave it reason to be cheerful,despite a rough first half to the year, and it is forecasting revenues up 20% in financial year 2004/05. Revenues from ip access, its in-building GSM unit, were up to £3million from less than half a million in the year previous. TTP is targetting £10million revenues from in-building business in the coming year.
There was also a good market reaction to the company's single processor modem, TTP said. The single processor configuration of its cellular baseband engine integrates the complete modem from RF drivers to protocol stack software (GSM, GPRS and EDGE) on the Digital Signal Processor (DSP). A single processor enables handset manufacturers to use the second processor for applications or open operating systems, whilst minimising silicon count.
TTP began interoperability testing of the single processor EDGE modem in March 2004.

Chip manufacturer Qualcomm has said that it has the largest number of manufacturers working with its WCDMA chipsets, compared to other chipset vendors. There are now 21 device and equipment vendors integrating Qualcomm's WCMDA chipsets, including newcomers Vitelcom Mobile Technology, BenQ Corporation and Misubishi. Established players such as Samsung, LG and Toshiba have long been Qualcomm licencees.

Dr Sanjay Jha, president of Qualcomm CDMA Technologies, said the broadening customer base would aid adoption of UMTS, as more products hit the market. Proven interoperability would reassure the operators, as well.
"We expect global adoption of WCDMA to accelerate as our customer base brings new products to market," Jha said. "Qualcomm's extensive interoperability testing, in addition to the testing we've conducted with our WCDMA operator partners, provides our handset customers with the confidence that their development efforts can remain focused on quickly addressing new market opportunities."
Qualcomm's chipsets support its Launchpad and BREW environments for application development, as well as J2mE environment. The chipset vendor views WCMDA as an ideal entry point into a European market previously off-limits in the GSM world. It has made efforts to ramp up its BREW presence in Europe, signing up a series of application development partners.
l Qualcomm has also announced it expects to launch an HSDPA chip in 2005. Qualcomm says samples of its radioOne RFR6275 diversity receive chip, which it says will increase network capacity and deliver higher speed data rates for the next-generation UMTS technology High Speed Downlink Packet Access, is expected to ship in the second quarter of 2005. 
The RFR6275 chip extends the functionality of the RTR6275 transceiver device, also just announced, to include support for HSDPA receive diversity and Assisted-GPS (A-GPS). 
The RFR6275 supports HSDPA receive diversity, which uses an additional antenna and associated receive chain to provide improved signal reception, enabling higher data throughput and significant increases in network capacity, especially in dense urban environments. This allows the RFR6275 to enable up to 5 dB receive diversity gain. This device also integrates a GPS receiver, which supports Qualcomm's gpsOne solution.

Mobileoperators and enterprises seeking to deploy high accuracy location based services can now move more rapidly to market – and to revenue – with a new breakthrough feature of CPS’ Matrix high accuracy location technology.

Matrix Solo can be integrated into a single standalone device – such as a vehicle tracker, child locator or handset – which will then deliver high accuracy in any environment and at sub-$1 per subscriber cost levels.
The new Solo feature means that operators can launch services now with just a single device and build revenues almost immediately before migrating seamlessly to full Matrix deployments. 
It will also allow enterprises to launch their own branded safety and security services – offering considerably better and more widespread coverage and accuracy than currently available GSM location technologies. Solo can operate successfully in areas where there are low levels of mobile traffic – such as rural areas or at night.
Matrix Solo works by “self-location” as the device moves – sending batches of previous location measurements to a network server that then calculates the handset’s position as required.
CPS CEO Chris Wade said: “Matrix Solo kick starts high accuracy for operators and enterprises. It means “go to market” and “get to revenue” timescales are radically reduced and opens up new opportunities for companies who experience poor performance from Cell-ID systems.”
Matrix Solo fills the enormous void in the mobile location-based services market for a low cost high accuracy technology that can be deployed easily and rapidly. At present, companies launching services – such as personal safety, child-finding or low cost logistics – are using Cell-ID technology. Based on a handset’s position within a mobile network cell-site  – location accuracy is based on the size of the cell within which it is located, which can be anything from, at best, 400m in urban areas to over 10km in suburban or rural environments.
As a result, service providers and users have been disappointed with the wide variability of the accuracy of the location – resulting in poor service take-up. Satellite-based positioning remains the preserve of high cost solutions for the logistics industry and, by its very nature, struggles to perform to user expectations in built-up urban environments and indoors.
The new Solo feature is now being trialled as part of Matrix trials in several locations around the world. It is expected to become commercially available in Q3 2004.
