{"ai_json_enabled":true,"answer":"Start by confirming the exact Comset model's band list and that Band 28 is supported alongside the other bands your carrier uses. Then run a real-site test with the intended SIM at the actual location to see how Band 28 behaves in practice. Set up a small on-site test with the selected router and a representative antenna. Record signal metrics like RSRP, RSRQ, SINR, and the actual throughput you achieve under typical load, across different times of day. Compare these readings to your required uptime and data usage rather than trusting coverage maps. If Band 28 results are borderline, try different antenna heights/positions or a different model that supports Band 28 and the needed bands. Also consider a short pilot to compare performance and reliability before committing. We can help by identifying which Comset models in your range support Band 28 and by providing a site-test plan tailored to your location.","answer_source":"approved_parent_and_related_qas","category":"4G LTE and 4GX Routers","category_slug":"4g-lte-and-4gx-routers","created_at":"2026-09-27T19:16:42+00:00","daily_publish_cap":2,"date_published":"2026-09-27","display_date":"2026-09-27","drip_batch":"daily_conversation_breadcrumb","drip_status":"published_topup","id":"conv-daily-20260927-4d7e86c3","image_ids":["comset-category-hero-003-4g-lte-and-4gx-routers","comset-product-cm685v-4","comset-product-cm685v-6"],"image_url":"","last_updated":"2026-09-27T19:17:13+00:00","local_cache_status":"pending_airtable_sync","publish_status":"published","published":true,"published_at":"2026-09-27T19:16:42+00:00","question":"How can I test Band 28 performance at my site before purchase?","question_intent":"conversational_followup","rss_enabled":true,"rss_pub_date":"Sun, 27 Sep 2026 19:16:42 GMT","scheduled_for":"2026-09-27T19:16:42+00:00","schema_enabled":true,"site_key":"comset-online","slug":"how-can-i-test-band-28-performance-at-my-site-before-purchase","source":"daily_qa_drip_conversational_followup","source_queue_id":"","source_record_ids":[],"source_type":"daily_qa_drip_conversational_followup","source_urls":[],"status":"active","tags":["conversation follow-up","daily drip"],"updated_at":"2026-09-27T19:17:13+00:00"}
