https://www.faststreamtech.com/knowledge/ Engineering writing on silicon, radio, edge AI, connected products and system integration from Faststream Technologies. en-GB Thu, 13 Aug 2026 09:00:00 +0000 https://www.faststreamtech.com/knowledge/drone-video-link-latency/ https://www.faststreamtech.com/knowledge/drone-video-link-latency/ Engineering Insight Thu, 13 Aug 2026 09:00:00 +0000 A radio quoted at twenty milliseconds can sit inside a system that takes four hundred. Glass to glass is the only figure that matters. https://www.faststreamtech.com/knowledge/camera-optics-for-inspection/ https://www.faststreamtech.com/knowledge/camera-optics-for-inspection/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 Most inspection systems that fail were decided at the lens, not at the model. Resolution runs backwards from the defect. https://www.faststreamtech.com/knowledge/rfid-nfc-uwb-compared/ https://www.faststreamtech.com/knowledge/rfid-nfc-uwb-compared/ Engineering Insight Thu, 13 Aug 2026 09:00:00 +0000 Three technologies answering three different questions. Choosing on the wrong axis is the expensive error here. https://www.faststreamtech.com/knowledge/uwb-ranging-explained/ https://www.faststreamtech.com/knowledge/uwb-ranging-explained/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 Thirty centimetres per nanosecond, so sub-metre accuracy is a sub-three-nanosecond timing problem. Everything hard follows from that. https://www.faststreamtech.com/knowledge/nr-cell-ssb-beams/ https://www.faststreamtech.com/knowledge/nr-cell-ssb-beams/ Engineering Insight Thu, 13 Aug 2026 09:00:00 +0000 A cell is now a synchronisation block and an identity, not a transmitter — which is why moving across a building need not generate a handover. https://www.faststreamtech.com/knowledge/radio-cascading-daisy-chain/ https://www.faststreamtech.com/knowledge/radio-cascading-daisy-chain/ Reference Architecture Thu, 13 Aug 2026 09:00:00 +0000 Bandwidth, timing accumulation and failure domain each bound the chain. The tightest one wins, and it is usually bandwidth. https://www.faststreamtech.com/knowledge/upf-placement-and-convergence/ https://www.faststreamtech.com/knowledge/upf-placement-and-convergence/ Reference Architecture Thu, 13 Aug 2026 09:00:00 +0000 Central, edge or cell site — the placement sets the latency floor. It is also the anchor where 5G and Wi-Fi converge on one session. https://www.faststreamtech.com/knowledge/evm-what-it-measures/ https://www.faststreamtech.com/knowledge/evm-what-it-measures/ Engineering Insight Thu, 13 Aug 2026 09:00:00 +0000 Six mechanisms degrade a constellation, they add in power, and the largest dominates — so decompose before optimising. https://www.faststreamtech.com/knowledge/linearisation-in-5g/ https://www.faststreamtech.com/knowledge/linearisation-in-5g/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 CFR and DPD exist because OFDM peaks sit where amplifiers are least efficient. That efficiency is a recurring operating cost. https://www.faststreamtech.com/knowledge/mocn-moran-neutral-host/ https://www.faststreamtech.com/knowledge/mocn-moran-neutral-host/ Reference Architecture Thu, 13 Aug 2026 09:00:00 +0000 What each model shares, the broadcast identity limit that caps tenants, and why sharing fails on operations rather than radio. https://www.faststreamtech.com/knowledge/n3iwf-non-3gpp-access/ https://www.faststreamtech.com/knowledge/n3iwf-non-3gpp-access/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 Reaching the 5G core over a network the operator does not own — and where that is cheaper than building coverage. https://www.faststreamtech.com/knowledge/anchor-bands-en-dc/ https://www.faststreamtech.com/knowledge/anchor-bands-en-dc/ Engineering Insight Thu, 13 Aug 2026 09:00:00 +0000 In non-standalone deployment 5G coverage cannot exceed the LTE anchor, which explains much of what users actually experience. https://www.faststreamtech.com/knowledge/cellular-for-smart-metering/ https://www.faststreamtech.com/knowledge/cellular-for-smart-metering/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 Decided by coverage in the worst basement in the estate, not by throughput — and by whether the network still exists in year twelve. https://www.faststreamtech.com/knowledge/connected-point-of-sale/ https://www.faststreamtech.com/knowledge/connected-point-of-sale/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 A payment terminal is a security product that happens to take payments. Tamper response and certification govern the schedule. https://www.faststreamtech.com/knowledge/item-level-tracking-high-value-logistics/ https://www.faststreamtech.com/knowledge/item-level-tracking-high-value-logistics/ Reference Architecture Thu, 13 Aug 2026 09:00:00 +0000 Density, custody handovers and tamper evidence — and why DECT NR+, with no operator and no base station, changes the arithmetic. https://www.faststreamtech.com/knowledge/fpga-to-asic-business-case/ https://www.faststreamtech.com/knowledge/fpga-to-asic-business-case/ Engineering Insight Thu, 13 Aug 2026 09:00:00 +0000 The volume arithmetic, the thresholds, the hidden costs estimates miss, and the cases where the honest answer is no. https://www.faststreamtech.com/knowledge/vision-plc-mes-integration/ https://www.faststreamtech.com/knowledge/vision-plc-mes-integration/ Reference Architecture Thu, 13 Aug 2026 09:00:00 +0000 Trigger and encoder, verdict timing, part tracking, reject actuation, the fault protocol and traceability. https://www.faststreamtech.com/knowledge/cellular-ntn-fallback-tracking/ https://www.faststreamtech.com/knowledge/cellular-ntn-fallback-tracking/ Technology Thu, 13 Aug 2026 09:00:00 +0000 How coverage continuity is architected, what escalation policy should look like, and what a satellite message actually costs. https://www.faststreamtech.com/knowledge/choosing-a-wireless-link/ https://www.faststreamtech.com/knowledge/choosing-a-wireless-link/ Reference Thu, 13 Aug 2026 09:00:00 +0000 NFC, RFID, BLE, UWB, LoRaWAN, cellular and satellite compared on range, accuracy, battery life and infrastructure. https://www.faststreamtech.com/knowledge/process-node-selection/ https://www.faststreamtech.com/knowledge/process-node-selection/ Engineering Insight Thu, 13 Aug 2026 09:00:00 +0000 Why 180 nm is frequently the right answer, and when an advanced node genuinely earns its mask cost. https://www.faststreamtech.com/knowledge/designing-ota-before-you-ship/ https://www.faststreamtech.com/knowledge/designing-ota-before-you-ship/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 Partition layout, bootloader design, signing and staged rollout — decisions that cannot be retrofitted into a deployed fleet. https://www.faststreamtech.com/knowledge/what-a-feasibility-study-produces/ https://www.faststreamtech.com/knowledge/what-a-feasibility-study-produces/ Application Note Thu, 13 Aug 2026 09:00:00 +0000 Two to six weeks, real parts, real conditions — and a written answer that is sometimes that it will not work as posed.
