{"answer":"Yes. Cat 4 and Cat 6 industrial routers remain suitable for many business and machine-to-machine jobs. Cat 4 can provide up to the class\u2019s theoretical 150 Mbps download rate, while Cat 6 can support higher theoretical throughput through carrier aggregation, but actual results depend on the carrier, tower load, signal quality, antennas and site conditions.\n\nMany applications use far less bandwidth: telemetry, PLC data, alarms, EFT or point-of-sale backup, remote equipment access and low-volume monitoring. In those cases, reliability, interfaces, VPN capability and remote management matter more than the maximum modem category. Cat 6 is useful when the site has heavier traffic or benefits from carrier aggregation, while 5G becomes more relevant for higher-capacity work. Comset should confirm that the chosen model supports the required Australian bands, SIM service and application interfaces.","approval_status":"draft_for_dave_review_pending_public_brain_audit","approved":false,"category":"4G LTE and 4GX Routers","category_slug":"4g-lte-and-4gx-routers","created_at":"2026-05-23T14:40:00+00:00","daily_publish_cap":2,"date_published":"2026-05-23","display_date":"2026-05-23","drip_status":"review_seed","freshness_note":"Confirm current model specifications, carrier compatibility, stock, pricing, firmware, warranty and commercial terms directly with Comset where they affect a decision.","id":"comset-qa-007","image_ids":["comset-product-cm685v-4","comset-product-cm685v-6","comset-product-cm820q-4","comset-category-hero-003-4g-lte-and-4gx-routers"],"language":"en-AU","last_updated":"2026-05-23T14:40:00+00:00","matched_image_ids":["comset-product-cm685v-4","comset-product-cm685v-6","comset-product-cm820q-4","comset-category-hero-003-4g-lte-and-4gx-routers"],"public_brain_verified":false,"publish_status":"review_preview","published_at":"2026-05-23T14:40:00+00:00","question":"Is a Cat 4 or Cat 6 industrial router still sufficient for many business and machine-to-machine applications?","question_intent":"public_guidance","question_type":"decision","real_image_mapping_status":"mapped_to_approved_comset_catalogue_v1_6","site_key":"comset","slug":"is-a-cat-4-or-cat-6-industrial-router-still-sufficient-for-many-business-and-machine-to-machine-applications","source":"Comset public website scrape and stable industrial-networking explanation","source_record_ids":["comset-source-0349","comset-source-0390","comset-source-0423","comset-source-0431"],"source_type":"client_source_plus_stable_explanatory_context","source_urls":["https://comset.com.au/what-is-lte-advanced","https://comset.com.au/product/4g-lte-cat-4-wifi-router-with-sim-card-slot-cm685v-4","https://comset.com.au/product/4g-4gx-lte-cat6-wifi-industrial-router-cm820q-6"],"tenant_slug":"comset","updated_at":"2026-05-23T14:40:00+00:00"}
