The connectivity buyer’s radar: 20 IoT technologies to watch in 2026–2027
Most “emerging IoT” lists sweep the whole stack and end up thin on the layer that actually decides whether a deployment ships: connectivity and the silicon underneath it. This radar does the opposite. Twenty technologies, weighted toward cellular, wide-area, short-range and edge hardware, each rated for where it genuinely sits going into 2026–2027 — not where a vendor deck says it should be.
The reference point for this kind of exercise is IoT Analytics’ emerging-technologies radar, and it remains a useful map. But its general-IoT radar now dates to 2022, and the 2026 refresh has moved upmarket into an industrial- and AI-weighted outlook where connectivity and hardware are compressed into a handful of the sixty-plus entries. That leaves a gap worth filling: a watchlist written from the connectivity buyer’s chair, by people who spend their days on modules, SIMs, spectrum and coverage rather than the application layer.
So this is not a whole-stack survey. You will not find digital twins, low-code platforms or generative AI here. What you will find is a sober read on the technologies that change what you can specify, source and deploy over the next two years — and an honest rating of how far off each one really is.
How we rate. Maturity runs Mainstream → Fairly mature → Nearing maturity → Coming up → Years out → On the horizon. Movement is our view of momentum through 2026–2027: Very fast (moving a full step within the window), Fast, Steady, or New entry (just arrived, one to watch). Ratings are editorial judgement, not a vendor scorecard — the point of a radar is a point of view.
A. Cellular & wide-area connectivity
This is the band that has moved most since the last general radar. RedCap has gone from specification to live UK networks; satellite has stopped being a proprietary silo and become a standards-based extension of ordinary cellular IoT; and remote SIM provisioning for headless devices has finally reached commercial availability.
| Technology | Why it matters | 2026–2027 rating | Movement |
|---|---|---|---|
| 5G RedCap (NR-Light, Rel-17) | The mid-tier 5G workhorse between NB-IoT and full NR. Commercial on two UK networks, with GCF-certified modules now shipping. Replaces LTE Cat-4 in gateways, wearables and CPE — but needs 5G Standalone. | Nearing maturity | Very fast |
| Satellite IoT (NB-IoT / LTE-M NTN, Rel-17) | Standardised satellite connectivity for ordinary NB-IoT modules — same SIM, same tooling, automatic fall-through to satellite where terrestrial fails. First commercial direct-to-device NTN services launching this window. | Nearing maturity | Very fast |
| SGP.32 IoT eSIM & eIM | Zero-touch remote provisioning purpose-built for screenless devices, with the eIM as the orchestration layer. Multiple end-to-end commercial launches through 2026; interoperability across vendors is the remaining friction. | Nearing maturity | Very fast |
| 5G FWA (fixed wireless access) | Fixed wireless broadband maturing into a credible fixed-line alternative, with RedCap-based CPE pushing the entry cost down. Increasingly a default for rural and rapid-deployment sites. | Fairly mature | Fast |
| 5G Standalone core + network slicing | The enabler beneath RedCap, slicing and deterministic QoS. Capability is real; UK coverage is still largely urban, making this a 2026–2028 rollout story rather than a done deal. | Nearing maturity | Steady |
| eRedCap (enhanced RedCap, Rel-18) | The lower-cost, lower-power successor to LTE Cat-1bis for the most constrained devices — smart meters, basic trackers, telematics. Modules emerging in 2026, volume expected from 2027. | Coming up | New entry |
| iSIM (integrated SIM) | The SIM function absorbed into the module or SoC secure enclave — the step beyond eSIM that removes the discrete chip entirely. Attractive for space-, cost- and power-constrained designs. | Coming up | Fast |
| Ultra RedCap (RedCap + NTN direction, Rel-19) | RedCap gaining satellite reach and further efficiency. Our shorthand, not official 3GPP language — and distinct from eRedCap. A genuine direction of travel, but a 2027-and-beyond proposition. | Years out | New entry |
B. Short-range, local & unlicensed
The unlicensed side is quieter but consequential. The long-running question of what replaces Zigbee is resolving into two answers — Thread-plus-Matter in the home, HaLow in industrial and outdoor — while a couple of newer entrants target problems neither cellular nor conventional Wi-Fi handles well.
| Technology | Why it matters | 2026–2027 rating | Movement |
|---|---|---|---|
| Wi-Fi 7 (802.11be) | High-throughput backbone for gateways, cameras and FWA CPE, with latency features relevant to industrial use. Premium mainstream now, cascading into IoT infrastructure. | Nearing maturity | Fast |
| Thread (802.15.4 IP mesh) | Low-power IP mesh; the transport under most Matter smart-building work. Quietly becoming the default residential low-power layer. | Nearing maturity | Steady |
| Matter | Cross-vendor application layer for smart home and building. Adoption is widening and platform backing is strong; real-world interoperability is still bedding in. | Coming up | Fast |
| Wi-Fi HaLow (802.11ah) | Sub-GHz, kilometre-range, low-power Wi-Fi with IP-native networking. Certified silicon now shipping from a small vendor base; industrial and agricultural deployments running ahead of consumer. | Coming up | Fast |
| UWB positioning | Centimetre-grade ranging for secure access, asset-finding and proximity. Ecosystem broadening beyond phones into IoT anchors and tags. | Coming up | Steady |
| DECT NR+ (5G non-cellular) | 3GPP-recognised, licence-exempt mesh for massive industrial sensor networks — no operator, no SIM, no monthly cost. Under-discussed and well-suited to private-site density. | Coming up | New entry |
C. Edge hardware & silicon
The hardware story of this window is intelligence moving onto the device. NPUs are appearing in mainstream module silicon; the packaging and instruction-set economics underneath are shifting; and at the far edge, two ideas — battery-less operation and the network as a sensor — are moving from paper toward products.
| Technology | Why it matters | 2026–2027 rating | Movement |
|---|---|---|---|
| Edge AI on IoT silicon (NPU-equipped MCUs/SoCs, TinyML) | On-device inference — anomaly detection, small-model vision, local audio — moving into mainstream module silicon via lightweight neural cores. The single biggest shift in what an endpoint can do unaided. | Nearing maturity | Very fast |
| Chiplets in edge silicon | Modular multi-die packaging delivering more capable, cost-optimised edge processors than a single monolithic die allows. Increasingly how mid-tier edge compute gets built. | Nearing maturity | Fast |
| RISC-V in IoT | Open instruction-set architecture winning designs in microcontrollers and edge SoCs. Licensing economics and toolchain maturity are the momentum here. | Coming up | Fast |
| Energy harvesting / battery-free sensors | Solar, RF, thermal and kinetic harvesting removing the battery from low-duty sensing. Still niche and application-specific, but the enabling piece for truly maintenance-free endpoints. | Years out | Steady |
| Ambient IoT (passive / backscatter, Rel-19) | Battery-less cellular tags powered by harvested RF, standardised in the frozen Release 19 for indoor inventory and command. Cellular products are still ahead of us; the proprietary, backscatter-over-BLE flavour is already deployed at scale. | On the horizon | New entry |
| ISAC (integrated sensing & communication, Rel-20) | The network itself acting as a sensor — detecting presence, motion and environment from the radio signal. A defining 5G-Advanced/6G-era capability, but years from products. | On the horizon | New entry |
The four genuine fast-movers. If you only track a handful, make them 5G RedCap, satellite NB-IoT NTN, SGP.32 eSIM orchestration and edge AI on module silicon. Each is crossing from “coming up” toward mainstream inside this window, and each changes a real procurement decision — the module you specify, the SIM you buy, the coverage you can promise, the processing you can do at the edge. The rest are worth watching; these four are worth planning around now.
One caution on the hype
Two entries on this radar attract more noise than their maturity justifies. Ambient IoT in its cellular form is a frozen specification, not a shipping product line — the deployments you hear about today are proprietary. And “Ultra RedCap”, useful shorthand though it is, describes a direction rather than a standard you can buy against. Both belong on the radar. Neither belongs in a 2026 deployment plan. The discipline a radar is meant to enforce is exactly this: knowing where a technology sits on the curve before you build a roadmap around it.
Method: twenty technologies selected for relevance to connectivity and edge-hardware buyers, rated by perceived maturity and momentum through 2026–2027. Maturity and movement are editorial judgement informed by 3GPP release status, module and chipset availability, operator deployment and published analyst forecasts (ABI Research, Omdia, GSA, Kaleido Intelligence). “Ultra RedCap” is our own shorthand for the Release 19 RedCap-plus-NTN direction and is not official 3GPP terminology. Ratings reflect the position at the time of writing and will move.
