A September 10, 2003 news index reported that Samsung had adopted a UWB chipset from XtremeSpectrum (XSI), just weeks after announcing a UWB development partnership with Staccato Communications. The report did not name a Samsung product or establish a production commitment. The move placed Samsung alongside companies working on competing proposals for a future UWB physical-layer standard, but it does not show that Samsung endorsed a final standard.
What did Samsung adopt?
The contemporaneous CommsDesign/EE Times news index described Samsung as adopting XSI’s chipset. XSI, or XtremeSpectrum, was a UWB chip company as well as a participant in standards development. The index said the reported adoption came only weeks after Samsung announced a UWB development partnership with Staccato Communications.
The accessible account does not identify a Samsung device, chipset model, shipment quantity, launch date, or manufacturing plan. “Adopted” should therefore be read as the news index’s wording, not as proof that a named consumer product reached the market.
What was XSI proposing for UWB?
XSI submitted “XSI Proposal 802.15.3a-2003” to the IEEE 802.15.3a task group. It proposed an alternate physical layer (PHY) for high-rate wireless personal-area networks (WPANs) based on ultra-wideband (UWB) technology. A PHY specifies how devices transmit and receive signals; competing PHY proposals can differ in waveform, channelization, implementation demands, and prospects for interoperability.

The proposal was part of a standards contest, not itself a completed IEEE standard. The IEEE task-group archive lists Samsung Advanced Institute of Technology’s Do-Hoon Kwon and Staccato Communications’ Roberto Aiello among contributors. IEEE presentation material also lists Samsung Electronics, Samsung/CUNY, Staccato, and XtremeSpectrum participants, and identifies location awareness and ranging as potential UWB capabilities.
Why were UWB standards contentious in 2003?
Companies needed to build products and respond to customer interest, but a shared standard mattered if equipment from different vendors was to interoperate. Until the IEEE process settled on a common approach, a company backing one implementation risked investing in technology that might not become the accepted standard.

- Supports IEEE802.15.4-2015 UWB & IEEE802.15.4z (BPRF mode)
- Supports channels 5 & 9 (6489.6MHz & 7987.2 MHz)
- Worldwide UWB Radio Regulatory compliance
- Location to an accuracy of 10 cm
- Control easily by AT commands
The dispute also involved regulatory uncertainty. In a filing to the National Telecommunications and Information Administration (NTIA), XSI said, “the industry is now going through the difficult process of developing global standards for UWB devices.” XSI argued that changing eligibility rules could add uncertainty and confusion and delay commercial availability. That is XSI’s stated position in the filing, rather than a neutral finding about the effects of any particular rule.
Customer demand added pressure to move before the standards process was finished. A November 17, 2003 RCR Wireless report described UWB companies as caught between standards pressure and customer demand, and reported that Motorola had acquired XtremeSpectrum. The acquisition illustrates the commercial stakes around UWB technology, but does not establish that Samsung’s reported chipset adoption became a commitment to a final standard.
Rank #3
- Based on DW1000 chip development, the module integrates antennas, all RF circuits, power management and clock modules.
- The module can use two-way ranging or TDOA positioning system, positioning accuracy of 10cm, data transmission rate of up to 6.8Mbps.
- Protocol standard: IEEE 802.15.4-2011 UWB , Spectrum range: 3.5-6.8GHZ
- Antenna form: PCB antenna on board, transmission distance is about 40 meters
- Power supply range: 2.8-3.6V default, 3.3V
Did Samsung back a final UWB standard?
The available records show Samsung involvement in the 802.15.3a work and a reported adoption of XSI’s chipset. They do not establish that Samsung endorsed a final 802.15.3a PHY, or that the reported adoption determined Samsung’s eventual products. XSI’s submission was a proposal within the standards process; participation and adoption are not the same as standards approval.
The distinction matters because the underlying IEEE 802.15.3-2003 high-rate WPAN standard and the proposed 802.15.3a alternate PHY are separate steps in the record. IEEE says 802.15.3-2003 was approved on June 12, 2003 and published on September 29, 2003; IEEE now marks that base standard as superseded. Those dates do not mean the 802.15.3a proposal had been adopted as the final UWB PHY.
