The interoperability of their chipsets allows for cellular/Wi-Fi solution Atheros Communications and CDMA giant Qualcomm recently demonstrated interoperability between their chipsets as they pursue an integrated cellular/Wi-Fi solution that can be used on most 3G networks.

“Qualcomm is integrating our software into their cellular stack — our solution is embedded in their reference design,” said Joseph Bousaba, Atheros Communications' director of marketing for mobile and embedded products. “So the [handset manufacturer] really doesn't need to do much.”

For enterprises, the ability to let employees use voice over IP via the enterprise Wi-Fi network offers improved in-building coverage for a mobile phone user. Such handsets have been available in the GSM market for some time, but their availability in the CDMA market has been limited to expensive smartphones, Bousaba said. “What Qualcomm is doing is bringing Wi-Fi functionality to the feature phone,” he said.

Miles Lee, vice president of analyst firm Adventis, agreed. “If you have separate chipsets external to the core handset and cellular functionality, it increases costs a bunch,” he said. “Dual-mode handsets just cost more than single-mode handsets. This [collaboration] is moving in the right direction in terms o f integrating multiple modes into a single chipset.”

Indeed, feature phones typically are priced at 50% of the cost of a smartphone, which should generate favorable economies of scale. Even with the Wi-Fi chip, the collaborative solution is expected to fit into the form factor of current handset models, Bousaba said.

The savings extends to power consumption as well, according to Lee. One of the reasons that dual-mode handsets thus far have been slow in gaining traction is that Wi-Fi is an energy-intensive technology. “It's similar to what occurs in a laptop computer,” Lee said. “An integrated wireless card will consume less battery power than an external card.”

Qualcomm has a similar partnership with Philips Semiconductor, but, “Atheros is the only supplier that can offer both 802.11g and 802.11a/g in the mobile space,” Bousaba said.

The Qualcomm/Atheros solution is scheduled to be commercially available in June. Initial versions of the chipset will not enable automatic handoffs between cellular and Wi-Fi networks, but allowing such seamless transitions is a goal of the Qualcomm/Atheros partnership, Bousaba said.

Qualcomm has a broader goal, Lee said. “Qualcomm's business model is to drive revenue by selling more chipsets, and integrating Wi-Fi onto a cellular chipset will help them do that. It also will help Qualcomm lock in its customers.”

GPS receivers and antennas

Trimble announced several additions to its line of GPS receivers and antennas designed for construction contractors. Modular GPS receivers and Smart GPS antennas both are capable of tracking next-generation L2C and L5 signals plus GLONASS, the company said. A new version of the company's SCS900 site-controller software also is being released to support the new receivers and recent developments in GPS positioning technology.

BREW-based P2T client

Clarity Communications has added a P2T client based on Qualcomm's BREW platform designed for the Kyocera KX440 handset. According to Clarity, the KX440 is Kyocera's first device that supports its inTouch client, which features a downloadable BREW client that uses VoIP and SIP technologies to deliver voice services over standard wireless packet data infrastructure. Because the BREW client is downloadable, users don't have to replace their handsets when they want to add new features, Clarity said. The handset's walkie-talkie function is accessed via a dedicated button on the side of the device.

‘Smallest’ RFID chip

Hitachi announced the development of a radio frequency identification chip that the company said is the thinnest and smallest such chip in the world, measuring 0.15 × 0.15 millimeters and 7.5 micrometers thick. Compared with the company's 0.3 × 0.3 mm IC chip, the new chip has a surface area and thickness that is one-fourth and one-eighth of the original, respectively. The smaller form factor increases the number of chips that can be fabricated on a single wafer, resulting in a four-fold increase in productivity, the company said.

Hitachi said it was able to reduce the distance between each circuit element through the use of silicon-on-insulator technology, which has an insulating layer in the substrate that lets high-frequency devices operate in close proximity without performance failures caused by interference.

P2T handset bridges GSM, WLAN networks

Nokia's Model 6136 handset offers P2T capability as well as audio and text messaging, and features unlicensed mobile access technology to let users seamlessly transition voice and data connections between GSM and WLAN networks. The company expects to ship the handset in the second quarter.

In addition, Nokia unveiled the Model 6070, a tri-band (GSM 850/ 1800/1900 or GSM 900/1800/1900) P2T handset for the European market that offers basic camera phone capabilities — as well as stereo FM radio, audio and text messaging, and e-mail — at an affordable price point. Initial shipments also are scheduled for the second quarter.

VoIP-based P2T client

Sonim Technologies has launched Xperience, a P2T-over-cellular client that is compliant with Open Mobile Alliance specifications and which provides IP-based voice communications. The client enables one-to-one, one-to-many and group communications; provides a contact list function that indicates presence and availability; and manages weak or intermittent radio signals, the company said. Sonim recently introduced a version of the client for Nokia's S60 Symbian-based smartphone platform, for which Nokia has manufactured about 28 million handsets.

Interoperability device

The ICRI-4TG interoperability device from Communications-Applied Technology creates up to four independent talk groups — which lets first responders from multiple agencies communicate at large-scale incidents — and complies with the National Incident Management System (NIMS), the company said. The ICRI-4TG is designed to let users divide networks into distinct talk groups via simple rotary switches. It operates on the VHF, UHF, and 800 MHz bands, supports digital/analog, trunked/talk-around and AM/FM platforms, and offers VoIP capability for operations where command and control is necessary for a wide range of responders. Several configurations and power options are available.

Hand-held RFID data terminal

Dietze Enterprises introduced the Nomad-RF, a lightweight, hand-held personal data terminal that uses RFID technology to capture mobile data. The device weighs 11 ounces and measures 7.8 inches × 3.1 inches × 2 inches. It works in conjunction with the recently introduced RFBadge — which contains an antenna, a transceiver (including decoder) and a transponder (RF chip/tag) that is electronically programmed with attendee information — to let event organizers capture information from attendee badges without the use of cumbersome readers. Users can transfer data from the Nomad-RF terminal to desktop and laptop computers via Bluetooth, USB, IrDA and RS-232 connections.

Otto Communications

The Mini-Com lapel speaker is the newest addition to the Vireo product line. It features an in-line microphone, eliminates the need for an earpiece and is designed specifically for users in the retail and hospitality sectors. Also available is the Lightsword speaker microphone, which features a “super bright” LED light that provides hands-free illumination of the immediate area. It also can be removed from the lapel and used as a mini-flashlight — for instance, by a police officer who wants to check a vehicle identification number or registration during a traffic stop — with minimal draw on the radio's battery. (Based on a 1500 mAh battery, one hour of lights-on operation is equal to about 30 seconds of radio transmit time, the company said.)
