Who is TDSR?

At TDSR, we are a core group of ultra-wideband (UWB) true believers, passionate about helping our customers implement UWB technology to solve real world problems.  Comprised of former colleagues from industry pioneer Time Domain, we bring unmatched expertise to the fieldour team averages over 20 years of UWB experience, spanning a wide range of applications. After being part of several acquisitions with Time Domain, we founded TDSR to reestablish worldwide sales, support new and existing customers, and advance the core technology with the release of the new 5G-compatible P452 ranging radio and radar sensor.

TDSR is led by Senter Reinhardt—the designer of numerous generations of UWB custom silicon and various radio platforms over the past 25 years, including the entire P4XX family. Alongside Senter, our team has developed advanced UWB 2D/3D radar systems, tracking systems, 2D/3D location systems, and UWB network systems.  Under his leadership, we remain committed to pushing the boundaries of what UWB technology can achieve and delivering cutting-edge solutions to our customers.  We’ve maintained decades-long business relationships by delivering consistent results, trustworthy service, and a deep understanding of each client’s unique needs.

Where does TDSR originate from?

Although TDSR is a completely new and separate entity with no formal connection to Time Domain or its acquirers, our entire team hails from the pioneering company that defined the UWB space. For those unfamiliar, Time Domain was a trailblazer in UWB technology, with a history so interesting it could easily be the subject of a Netflix series or a staple in business school case studies. Time Domain held the most UWB patents, raised the highest amount of investment funds, built the largest UWB-focused team, developed the world’s first UWB baseband chip, and was the first company to produce and sell chips using IBM’s Silicon Germanium (SiGe) process. The company also introduced multiple UWB product lines, spearheaded the regulatory effort that legalized UWB for commercial use in the U.S., and played a pivotal role in launching many competitors in the UWB and RTLS markets.

Time Domain’s journey had its share of highs and lows, but one constant remained: the team’s deep commitment to each other, to the technology, and to long-standing customers—some of whom have been using PulsON products since the P200 back in the early 2000s. To this day, Time Domain alumni still gather at reunion events, reflecting the enduring bonds formed over decades in the UWB space. TDSR extends a heartfelt thank you to all our former colleagues, customers, and friends for your contributions in shaping the UWB industry and its history.

Larry Fullerton founded MidSouth Technology, which eventually became Time Domain Systems, Inc. (TDSI).  It was largely a small “garage shop” operation working on small contracts with the goal to prove the fundamentals of UWB technology were possible. Larry was an extraordinary visionary who created many technologies and businesses.


TDSI had an Atlanta-based licensee called Pulson Communication. TDSI acquired Pulson Communication and “PulsON” later became a product brand for Time Domain.

1987

TDSR Founder, Senter Reinhardt, joined TDSI before Petroff investment.

Tech at this time: Early UWB demonstrators developed — comms, ranging and radar. Made from discrete components and requiring very manual, hands-on, engineer-in-the-loop operation.

1996


Petroff Family made large personal investment into Time Domain, and became leadership team. Over time, the Petroff’s raised well over $100M to further UWB development and pursue regulatory approval.

TDSI became Time Domain Corp (TDC)

Several current TDSR employees joined TDC during this timeframe.

Time Domain acquired; becomes wholly-owned subsidiary of Carlsbad, CA-based 5D Robotics in 2016

2016 – 2018




5D Robotics/Time Domain acquired by Boston-based Humatics Corporation in 2018



Senter founds TDSR and works with Humatics on a mutually beneficial license agreement to continue research and development of the P440, with the goal of selling horizontal sensors, modules, and kits based on P440.



Due to 5G rollout and associated jamming issues, TDSR discontinues P440 radio family.
In response to 5G, TDSR invests 2 years of R&D to design / release all new P45x ranging radio / radar line that comes in both 5G Safe and Full Band models. 


TDSR begins work to expand its product line by leveraging an alternative UWB technology, paving the way for greater versatility and expanded possibilities to meet the evolving needs of our customers. 

2020 – present

Early 2020 – Humatics changes its business model to focus on larger, higher value vertical markets, with a special emphasis on rail, while discontinuing the module and kit sales business.


FCC acts to accelerates deployment of 5G wireless systems, which cut deeply into the spectrum used by UWB for the previous 20 years.
