ANSpect Technologies claims its technology delivers an additional 35 to 80 Mbit/s of upstream capacity from the 5 MHz–42 MHz "low-split" portion of North American DOCSIS spectrum, a 35% to 85% throughput increase relative to ATDMA-only channels on legacy cable plant.

The startup, founded in late 2025 and now seven employees strong, demonstrated its approach at the recent SCTE Tech Expo in Atlanta using Calian test equipment. It emulated a cable modem and showed how its channels can run alongside legacy ATDMA carriers.

What is driving the upstream push?

The pitch lands against a measurable shift in traffic patterns. OpenVault's Q2 2026 Broadband Insights report found average upstream usage on DOCSIS networks grew 19.2% to 58.2 gigabytes per subscriber, while downstream usage declined 6.1%.

The downstream-to-upstream ratio compressed from 16.6:1 in 2019 to 11.2:1 in Q2 2026, OpenVault said. Average provisioned upstream speeds climbed 33.7% to 47.3 Mbit/s in the same period as operators deploy OFDMA subcarriers introduced with DOCSIS 3.1, push mid-split and high-split upgrades, and begin DOCSIS 4.0 migrations.

OpenVault described the upstream tilt as structural rather than seasonal, driven by video conferencing and cloud-device synchronization.

What does ANSpect's approach actually change?

The company targets gear already in the field. ANSpect runs proprietary channels alongside ATDMA carriers in spectrum DOCSIS has used for three decades, extracting additional bits without disturbing the legacy service.

"We're taking old spectrum and getting new bits out of it," John Chapman, ANSpect's SVP and chief strategy officer, cable, said. "It's almost like a virtual node split in the upstream."

Chapman, a DOCSIS pioneer and former Cisco Systems executive, framed the technology as a way to extend the useful life of DOCSIS 3.0 and DOCSIS 3.1 modems that speak ATDMA. He estimated the approach can nearly double the upstream capacity on such devices.

"I would submit that ATDMA under-utilizes the spectrum," Chapman said. "We can make that DOCSIS 3.0 and DOCSIS 3.1 service in the upstream work better. … We mine, out of thin air, the unused bits that ATDMA has not already mined out of there. It's like we're dressing up ATDMA to act like OFDMA."

ANSpect declined to detail how it creates the new channels. The company intends to license its technology to cable network suppliers for deployment on hybrid fiber-coax plants that already operate a virtual cable modem termination system (vCMTS) with either a remote PHY device (RPD) at the node or a remote PHY shelf at the headend.

Why does the timing favor ANSpect?

The startup arrives as Cisco's cBR-8, a long-standing CMTS workhorse, enters end-of-life, and operators migrate to vCMTS architectures. Chapman said ANSpect intends to ride that migration.

Deployment could take the form of a software upgrade on RPDs built around field-programmable gate arrays, with a hardware add-on under evaluation for ASIC-based RPDs, according to Dr. Ahsan Naim, ANSpect co-founder and CTO. The technology works with existing DOCSIS modems, the company said.

What happens next?

Field trials are scheduled for 2027, co-founder and CEO Surya Panditi said. A software-only path could produce early-2027 trials; both software and hardware tracks remain feasible within the calendar year.

Upstream capacity remains the company's focus. Chapman noted the same technique could deliver up to 2 Gbit/s of additional capacity from the DOCSIS downstream at a later date. ANSpect is also participating in the Commonwealth Cyber Initiative's xG Testbed at Virginia Tech alongside AT&T, Verizon, Samsung and SoftBank, evaluating its O-EMA orthogonal-enhanced multiple access scheme for indoor and outdoor wireless applications.

ANSpect remains pre-revenue and funded by an undisclosed pre-seed round. Panditi said follow-on fundraising is under consideration after expressions of interest from two mobile technology suppliers. Software-led trials in early 2027 will set the pace for any commercial rollout.
