Pulse~LINK DEMONSTRATES SIMULTANEOUS TRANSMISSIONS OF NARROWBAND AND ULTRA WIDEBAND COMMUNICATIONS ON A SINGLE CHIP AT ULTRA WIDEBAND WORLD CONFERENCE
In Addition to Integrating Narrowband Technologies Such as WiFi and Bluetooth, Pulse~LINK Demonstrations Show How Platform Could Support Both MBOA and Direct Sequence UWB Technologies on the Same Chipset.
SAN JOSE, Calif., Sept. 28 -- At the Ultra Wideband World conference held in San Jose, Calif. today, Pulse~LINK announced the first public demonstrations of its RF ASIC capable of simultaneously transmitting Ultra Wideband communications wirelessly, over cable television networks and electrical wiring, as well as narrowband communications such as WiFi and Bluetooth. The demonstrated technology has tremendous implications for several fields of communications integration spanning Ultra Wideband communications, narrowband communications and Software Defined Radio.
The simultaneous transmission of each of these communications types from a common chipset is made possible by Pulse~LINK's latest Digital to Analog Converter (DAC) 0.18 micron Silicon Germanium test chip. With performance tested up to 20 Giga-samples per second, the Pulse~LINK DAC can perform direct digital synthesis of any UWB pulse shape or narrowband carrier between DC and 10Ghz of spectrum. At the conference, Pulse~LINK demonstrated its DAC generating pulses shaped specifically for UWB communications across in-home electrical wiring, UWB communications on a 750Mhz cable television network, wireless UWB communications covering multiple modulation techniques and narrowband carriers at 2.4Ghz that is used for WiFi 802.11b/g and Bluetooth, as well as at 5.1Ghz to 5.3Ghz that is used for WiFi 802.11a. All of these were demonstrated in simultaneous operation from a single chip.
With silicon that is capable of direct digital synthesis of virtually any communications waveform beneath 10Ghz, the implication is that a common chipset hardware platform can be made to perform a tremendous range of communications functions through software control. Within Ultra Wideband wireless communications, the Pulse~LINK platform could support either of the two competing UWB Wireless PAN standards proposals, or both, alongside Pulse~LINK's own UWB Wireless LAN, UWB Cable and UWB Power Line Communications -- all from the same chipset. Integration of WiFi and Bluetooth technologies would allow interoperability with those technologies where already deployed. Ultimately, the ability to support multiple forms of communications from a single chipset whose functionality is defined by software fulfills a core definition of Software Defined Radio and Pulse~LINK's long term goals.
In addition to the demonstration of its DAC silicon, Pulse~LINK also conducted public demonstrations of multiple streams of High Definition Television being delivered via Pulse~LINK's UWB Cable, Power Line and Wireless technologies.
Pulse~LINK's UWB cable demonstration was conducted utilizing a
miniature version of a metropolitan area Hybrid Fiber Coax
infrastructure featuring multiple streams of standard cable
television feeds operating simultaneously in the presence of UWB
enabled HDTV content. The cable network demonstration consisted of
industry standard off-the-shelf CATV equipment beginning at the
"Cable Operator's head-end," across fiber optic cable to a "fiber
field node," through more than 1000 feet of coax cable and two
"field amplifiers," through multiple RF splitters and into a
"digital living room" where both the UWB HDTV broadcasts and
standard NTSC cable broadcasts were displayed simultaneously.
Pulse~LINK's wireless UWB demonstrations showcased simultaneous
transmissions of two HDTV programs from one UWB wireless radio
into separate HDTVs. Demonstrations of HDTV transmitted via UWB
across active electrical wiring were also conducted at the event.
