IPWireless develops an advanced, 3G standards-based mobile broadband and multimedia technology called UMTS TD-CDMA (also called UMTS TDD), the high-speed solution designed for mobile operators that drastically improves the way people around the world connect and communicate at home, at the office or on the road. With a full range of commercially available network solutions and devices based on the UMTS TD-CDMA standard, they allow operators to offer a spectrum of completely mobile, portable, or stationary packet-based services with unmatched economics and true broadband performance.
UMTS TD-CDMA’s high average sector capacity, strong cell edge performance, and low cost per megabit make it an ideal technology for mass-market mobile broadband networks. It has emerged as a leading global standard for mobile broadband with deployments in numerous countries around the world including Australia, the Czech Republic, Germany, Malaysia, New Zealand, Nigeria, South Africa, the United Kingdom, and the United States. IPWireless has more than 30 global deployments/trials with tier one operators such as Sprint Nextel, T-Mobile, Orange, and PCCW, along with OEM partnerships with industry leaders such as UTStarcom and Alcatel. A nationwide network is rolled out by Woosh Wireless in New Zealand, which launched the world’s first commercial VoIP offering over a TD-CDMA mobile broadband network in September 2005. In Australia, IQ Networks announced the rollout of a network in 2004 for coverage in Townsville and Cairns in the 1900-1920MHz spectrum.
UMTS TD-CDMA operates in a non line-of-sight environment allowing fast wireless data access indoor, outdoor and in vehicular mobility environments. The technology has higher performance, greater flexibility and lower lifetime costs than existing mobile data access offerings such as FDD UMTS, CDMA 2000, GPRS, and proprietary technologies. The air interface technology utilises advanced signal processing techniques that results in higher throughput – combined downlink and uplink data rates up to 16Mb/s (peak rates); 90% of coverage is within 10km.
UMTS TD-CDMA can be deployed in a very similar manner to a cellular network, with the flexibility of omni, three and six sector cells. An existing cellular operator can leverage a great deal of its existing and planned network infrastructure in deploying the IPWireless solution.
The equipment is built on, and complies with the 3G Project Partnership (3GPP) UMTS TDD standard. 3GPP is the international standards body that develops, publishes and maintains standards for third generation wireless. The 3GPP family of standards consists on three alternative air-interface (physical layer) standards. These air-interface standards are: FDD WCDMA, UMTS TDD, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA). UTMS TDD is a packet data implementation. Time-division-duplex is used, allowing operation on unpaired spectrum anywhere in these bands.
In January 2006, IPWireless entered the mobile TV space with the launch of TDtv, a Multimedia Broadcast and Multicast Standard (MBMS)-based offering that enables mobile operators to deploy mobile TV using their existing 3G spectrum and cell site infrastructure. This is a huge advantage over competing technologies such as DVB-H and MediaFLO, both of which require separate networks. TDtv also allows operators to maintain control of mobile TV services, as opposed to sharing it with broadcasters. Orange is trialing TDtv in the UK, IPMobile is deploying TDtv in Japan and Sprint Nextel is testing TDtv as part of its ongoing UMTS TD-CDMA trial in the U.S. To date, IPWireless has announced two TDtv partnerships with MobiTV, a content provider, and Vidiator, a mobile multimedia streaming company, to develop next-generation mobile TV delivery solutions.
In February 2006, Sprint Nextel announced that it would be the first operator globally to test the next generation of IPWireless’ mobile broadband technology, which is progressive to Long Term Evolution (LTE) for the 2.5GHz Band. Beyond Sprint Nextel, the true value of IPWireless and UMTS TD-CDMA has to do with Long Term Evolution, or LTE. The technology direction for LTE has been set by operators and vendors, and it shares fundamental principles with TD-CDMA. In fact, IPWireless LTE Progression Platform offers operators the only software-upgrade path to LTE.
• Self Contained Transmissions:
? Allows different modulation in different slots: OFDM, SC-FDMA, CDMA.
• Common Frame Structure:
? LTE and TD-CDMA can coexist on the same carrier, in different sub-frames, or;
? RF coexistence on adjacent carriers.
• Benefits:
? Backward compatibility (LTE/TD-CDMA) so operators can deliver LTE type services more than three years early and migrate to LTE;
? Support for paired and unpaired operation;
? Variable duplex spacing.
The IPWireless Partner Program and chipsets allow device manufacturers and infrastructure vendors to very quickly bring innovative new TD-CDMA solutions to market. The company is currently shipping an end-to-end TD-CDMA solution including end user equipment, network infrastructure and software, and third party devices. Consumer devices include both PCMCIAs for laptops, PDAs and Tablet PC’s, as well as desktop modems that use either USB or Ethernet to support PCs and LAN Gateways. Both devices are plug-and-play, use extremely low power and support downlink speeds of up to 3Mb/s. Both devices are also equipped with SIM card readers to support secure provisioning, authentication and roaming.
In May of this year, IPWireless was selected by FierceWireless as one of the “Fierce 15,” an annual award recognizing the top 15 emerging wireless companies. This followed on the heels of an additional $10M investment from Sprint Nextel in January 2006, which brings the total funding to $14M. Sprint Nextel has made it very clear that they are going to decide which technology to deploy in their 2.5 GHz spectrum by this summer and right now, based on media and analyst reports, UMTS TD-CDMA is one of the leading remaining candidates for deployment. If UMTS TD-CDMA is selected it will thrust IPWireless into the top echelon of the industry and greatly increase the speed at which TD-CDMA will be embedded into wireless devices and handsets.
