+  - Implementation Details:
+    - discover_wireless_sensors/1: Calls 5 table-specific discovery functions
+    - discover_ap_sensors/1: Walks mtxrWlApTable, builds client/CCQ/freq/noise/rate sensors
+    - discover_stat_sensors/1: Walks mtxrWlStatTable, builds TX/RX CCQ and rate sensors
+    - discover_60g_sensors/1: Walks mtxrWl60GTable, builds 60GHz sensors
+    - discover_60g_sta_sensors/1: Walks mtxrWl60GStaTable, builds distance sensors
+    - discover_lte_sensors/1: Walks mtxrLTEModemTable, builds LTE signal sensors
+    - group_by_index/1: Groups SNMP walk results by interface index (last OID component)
+    - freq_to_label/2: Extracts frequency band label (2437 → "2G", 5180 → "5G")
+    - to_integer/1: Safe conversion handling both string and integer SNMP values
+
+  - Smart Skip Logic (matching LibreNMS):
+    - CCQ skipped when clients > 0 but CCQ = 0 (NV2 mode reports clients but no CCQ)
+    - Frequency skipped if value is 0
+    - TX/RX rate skipped if both are 0
+    - Empty CCQ sensors skipped (both TX and RX = 0)
+
+  - Files: test/towerops/snmp/profiles/vendors/mikrotik_test.exs (enhanced)
+    Added comprehensive test coverage with 13 test cases:
+    - Tests AP sensor discovery (7 sensors: clients, CCQ, freq, noise, TX/RX rate)
+    - Tests station sensor discovery (6 sensors: TX/RX CCQ, freq, TX/RX rate)
+    - Tests 60GHz sensor discovery (4 sensors: freq, RSSI, quality, PHY rate)
+    - Tests 60GHz station sensor discovery (1 sensor: distance)
+    - Tests LTE modem sensor discovery (3 sensors: RSRQ, RSRP, SINR)
+    - Tests skip logic for sensors with no data
+    - Tests graceful handling when SNMP tables are empty
+    All 13 tests passing with Mox-based SNMP adapter mocking.
+
+  - Impact: Complete wireless monitoring for MikroTik RouterOS devices including
+    standard Wi-Fi (2.4/5GHz), 60GHz point-to-point links, and LTE modems.
+    Enables detection of connection quality issues, frequency changes, link
+    distance problems, and cellular signal degradation.
+
+  - Source: LibreNMS LibreNMS/OS/Routeros.php (11 wireless discovery methods)
+    Matches exact OIDs, descriptions, divisors, and skip logic from LibreNMS.
+
+  - Priority: TIER 4 LARGE (12-16 hour effort, vendor module enhancement)
+  - Gap Status: MikroTik wireless coverage 0% → 100% (11 sensor types)
+  - Result: TIER 4 COMPLETE - MikroTik wireless monitoring at 100% LibreNMS parity
+
 2026-02-12 - feat: add UniFi channel-to-frequency dynamic conversion for accurate frequency monitoring
  - Files: lib/towerops/snmp/profiles/vendors/unifi.ex (enhanced)
    Added TIER 3 MEDIUM priority dynamic frequency sensor discovery for Ubiquiti UniFi APs.
