Nokia demos AI‑powered 6G receiver at Brooklyn 6G Summit, promising 10–25% uplink gains and reuse of existing 5G sites
  • What’s new: Nokia and Rohde & Schwarz showcased an AI‑powered 6G receiver prototype at the Brooklyn 6G Summit this week. The proof‑of‑concept targets one of 6G’s toughest problems: coverage at higher frequencies. [1]
  • Why it matters: Nokia says machine‑learning techniques can extend uplink distance by ~10–25% versus today’s receivers, enabling operators to roll out 6G over current 5G footprints, lowering cost and speeding time‑to‑market. [2]
  • Where it runs: A research radio operating between ~7 and 30 GHz—aligned with the upper mid‑band/FR3 focus for early 6G—was shown on the expo floor. [3]
  • Context: The demo caps a season of AI‑centric wireless news that includes NVIDIA’s $1 billion strategic investment in Nokia to accelerate AI‑RAN and the transition from 5G‑Advanced to 6G. [4]

What Nokia showed in Brooklyn

On the final day of the Brooklyn 6G Summit (Nov. 5–7, 2025)—co‑hosted by Nokia and NYU WIRELESS—Nokia highlighted HybridDeepRx, an AI‑enabled receiver designed to improve 6G coverage without a wholesale rebuild of cell sites. According to Nokia Bell Labs researcher Dani Korpi, the lab radio under test spans roughly 7–30 GHz, and pairs with an AI receiver to tolerate higher, distortion‑prone transmit powers—translating into a few extra dB of link budget. [5]

Nokia says the approach can boost uplink distance by 10–25% under realistic test conditions, a gain validated with Rohde & Schwarz gear (including an SMW200A vector signal generator and FSW signal & spectrum analyzer used for the AI inference workflow). Those improvements, if carried into products, could allow 6G to ride on existing 5G sites, cutting coverage‑driven capex. [6]

The HybridDeepRx demo is listed among the event’s featured exhibits, underscoring its role as a near‑term building block in AI‑native radio research. [7]

Why this matters: beating physics (with ML)

Higher‑frequency spectrum central to early 6G plans offers wider channels but shorter reach, forcing denser networks. Nokia’s AI receiver tackles the non‑linear distortion that creeps in when user devices push power amplifiers hard—typically a recipe for degraded error‑vector magnitude (EVM) and shorter uplink. By learning and compensating for those distortions (including digital post‑distortion techniques) the receiver recovers clean bits at longer ranges. That is the core of Nokia’s coverage claim and the premise for lower site counts in 6G overlays. [8]

Partnership details: Nokia × Rohde & Schwarz

Per the companies’ announcements, Nokia Bell Labs developed the receiver and ran validation using Rohde & Schwarz 6G test methods and instruments. The parties unveiled the proof‑of‑concept at B6GS on Nov. 6, positioning it as pre‑standardization technology aimed at accelerating 6G time‑to‑market. [9]

Light Reading’s Europe brief similarly flagged the tie‑up, noting Nokia’s claim that ML extends uplink distance by up to 25%, directly addressing FR3 coverage limits. [10]

A season of AI‑RAN momentum around Nokia

Beyond this week’s lab demo, Nokia has become a focal point for AI‑RAN investment. Late last month, NVIDIA and Nokia announced a strategic partnership to bring NVIDIA‑powered AI‑RAN products into Nokia’s RAN portfolio—paired with a $1 billion equity investment (about 2.9% stake) at $6.01 per share. The deal underlines the industry push to make AI a native part of the wireless stack from Layer‑1 up, and to bridge today’s 5G‑Advanced with tomorrow’s 6G. [11]

What’s next

  • From demo to drafts: The receiver is still pre‑standard, but proofs like HybridDeepRx help shape 3GPP 6G requirements and trials expected to ramp later in the decade. Nokia’s Korpi also reminded that commercial 6G isn’t expected before ~2030—this is groundwork for that timeline. [12]
  • Ecosystem validation: Expect more vendors and operators to reproduce the AI‑receiver results under multi‑vendor testbeds to understand coverage uplift vs. device power and network density trade‑offs.
  • Cost calculus: If operators can reuse existing 5G site grids for wide‑area 6G, the AI receiver could become a high‑leverage feature for early deployments in FR3 bands. [13]

Key quotes (edited for brevity)

  • Nokia Bell Labs on coverage: AI helps address “coverage limitations inherent in 6G’s higher‑frequency spectrum” by boosting uplink distance, with tests showing 10–25% gains. [14]
  • Fierce Network from the show floor: Nokia’s AI receiver lets radios “detect higher transmit powers… which are distorted,” delivering a few dB of improvement in practice. [15]

  • The Little-Known Android Clipboard Manager Shortcut I Use Every Day
    November 9, 2025, 5:56 PM EST. Android's Clipboard manager extends the basic clipboard by storing text, links, images, and screenshots for later paste. It lets you copy items in bulk, manage multiple entries, and keep them available across actions until they're expired after an approximate hour (with pinned items exempt). This makes Android noticeably faster and more flexible than iOS, which typically only stores the most recent clip. In practice, you can save repeated text and media inside the Clipboard manager and paste from it later in any keyboard app. It's easy to use on popular devices, and it helps reduce clutter while avoiding repeated retyping.

  • Apple's Decade-Long Satellite Vision Expands Beyond Emergency SOS
    November 9, 2025, 5:48 PM EST. Apple's decade-long satellite vision expands beyond Emergency SOS via Satellite to a broader set of services. Led by the Satellite Connectivity Group and director Mike Trela, Apple links compatible iPhones and the Apple Watch Ultra 3 to a Globalstar network, with plans for satellite-powered maps, enhanced messaging, and a framework for third-party apps. Since SOS launched in 2022, Apple added roadside assistance with AAA and remote-texting in remote areas, signaling a cautious but meaningful expansion rather than a full cellular replacement. While Globalstar weighs a sale and SpaceX/Starlink reshapes the field, Apple remains committed to evolving satellite services, aided by plans for in-house modems and potential iPad support, underscoring its long-term vision.
