OMRON LD series network requirements
OMRON's AMR wireless guide asks for at least -60 dBm, round-trip latency of 10 ms recommended and 50 ms at most, and about 50 kbps per AMR, with constant coverage across the workspace.

Values
| Parameter | Value | Condition |
|---|---|---|
| Minimum signal strength | -60 dBm1 | Recommended minimum; OMRON gives -40 dBm or stronger as the ideal case |
| Minimum signal-to-noise ratio | Not published by the vendor1 | Checked the wireless network requirements section |
| Latency, recommended | 10 ms1 | Round-trip time, measured with a ping test; OMRON calls 10 ms very low latency |
| Latency, maximum allowable | 50 ms1 | Round-trip time, from the wireless guide. The LD-60/90 Platform User's Manual gives 10 ms as the maximum recommended round trip and does not state this 50 ms ceiling (next row) |
| Latency, LD platform manual | 10 ms2 | Maximum recommended round-trip time in the LD-60/90 manual's wireless specification table, which gives no higher ceiling; the wireless guide allows up to 50 ms (previous row) |
| Minimum signal strength, LD platform manual | -60 dBm2 | Same figure as the wireless guide |
| Co-channel access points | No more than two detectable access points at -85 dBm, and no more than one above -85 dBm, at any location2 | Listed as Channel Interference in the LD-60/90 manual's wireless specification table |
| Jitter limit | Not published by the vendor1 | Checked the wireless network requirements section |
| Maximum roam time | Not published by the vendor1 | The guide asks the site survey to note predicted roam locations but gives no roam-time figure |
| Bandwidth per AMR, average | 50 kbps1 | Varies with configuration, MobilePlanner and other client activity |
| Bandwidth per AMR, while monitored | 500 kbps1 | When the AMR is being monitored by MobilePlanner |
| Wireless standards | 802.11a (recommended), 802.11b, 802.11g1 | OMRON still supports 802.11b but does not recommend it |
| Wireless standard, LD series datasheet | IEEE 802.11 a/b/g3 | Listed under Standards for the LD series AMRs |
| Wi-Fi card, as named in OMRON's troubleshooting table | AC72601 | OMRON's troubleshooting table tells you to confirm a failed LD Wi-Fi card (AC7260). The datasheet lists 802.11 a/b/g; see the next row for the card's own capabilities |
| Wi-Fi card capabilities, Intel listing | 802.11ac, 2x2, 2.4 GHz and 5 GHz; launched Q2 2013; discontinued4 | Intel's listing for the Dual Band Wireless-AC 7260, the Intel adapter that carries the AC7260 model number. OMRON names the card only as AC7260 |
| Supported bands | 2.4 GHz and 5 GHz1 | Available channels vary by band and region |
| Channel width | Not published by the vendor1 | The guide describes 5 GHz channel widths in general but states no width for the AMRs |
| Wi-Fi security methods | Open, WPA-PSK, WPA2-PSK, PEAP-MSCHAPv2, EAP-TLS1 | |
| Wi-Fi encryption | TKIP/RC4, CCMP/AES or TKIP/CCMP/AES; 64-bit and 128-bit WEP also selectable5 | Set in SetNetGo to match the network; authentication options are open, WPA-PSK, PEAP-MSCHAPv2 and EAP-TLS. No WPA3 option is listed |
| Roam scan settings | Background scan every 3 s by default; scanning drops to one tenth as often while signal is above the RSSI roam threshold (default 50, unit not stated)5 | OMRON states roam times are faster with fewer channels selected in the channel set, and that the Auto radio mode may lead to longer roam times |
| Wireless watchdog | Optional; if pings to the Fleet Manager (or the gateway) fail for the Watchdog Timer period, the AMR resets its wireless interface and tries to reconnect5 | Timer set by the user in SetNetGo; no default value published |
| Fleet Manager failover reconnection | 1 to 3 minutes5 | Time for AMRs to reconnect to a new Primary Fleet Manager and resume operation after the primary fails, depending on network configuration |
| Fast roaming support | Not published by the vendor1 | The guide does not mention 802.11r, 802.11k, 802.11v or key caching |
| Ports, AMR to Fleet Manager | TCP 37; TCP/UDP 5000; TCP/UDP 7272; UDP 10000 and up1 | Intra-fleet traffic for configuration updates, job dispatch and shared position and trajectory updates. Allocate at least twice as many UDP ports from 10000 as there are AMRs (for example 10000 to 10039 for 20 AMRs). Bidirectional traffic must be allowed |
| Ports, Integration Toolkit | TCP 1884, 5672 (RabbitMQ AMQP), 8443 (ITK REST), 5432 (PostgreSQL)1 | Excludes dynamically allocated port numbers |
| Ports, clients and WMS or MES | TCP 443 and TCP/UDP 7272 and up from client PCs; TCP 7171 (ARCL) from WMS or MES1 | Each AMR connection uses the next port from 7272 (OMRON suggests allowing 7272 to 7999). The ARCL port is configurable and open only if the ARCL server is enabled |
| Coverage | Constant access throughout the workspace1 | OMRON calls constant access an operational requirement for AMR fleets and recommends a dedicated network restricted to the AMRs |
| Effect of a poor connection | Frequent disconnections may leave an AMR unable to reconnect, requiring user intervention1 | OMRON also lists packet loss leading to failed jobs or goals, and collisions among AMRs in close proximity |
| Operation without a wireless connection | Only where no other AMRs are present2 | Alone, the AMR navigates on its stored map; with other AMRs in the area, a wireless connection to the Fleet Manager is required. The LD-60/90 manual states this, and the HD-1500 and OL-series manuals use the same words. No OMRON document checked says what an AMR does when the link drops mid-job |
| Product status, Europe | LD-60, LD-90, LD-90x and LD-250 discontinued; final order November 15, 2026; final shipment December 31, 2026; maintenance close June 30, 20326 | Europe-only notice. OMRON names the new LD-150 and LD-300, available Q4 2026, as replacements and recommends migrating to FLOW Core v5.x first |
When it loses the network
- Behavior
- A single AMR can keep navigating without Wi-Fi on its stored map; in a fleet, Fleet Manager connectivity is required. OMRON does not state whether a fleet AMR stops, finishes its job, or continues when the link drops, and warns that frequent disconnections may leave an AMR unable to reconnect.
- Timeout
- Wireless watchdog timer, set by the user in SetNetGo; no default published5
- Recovery
- With the watchdog enabled, the AMR resets its wireless interface and tries to reconnect; otherwise user intervention may be needed. After a Fleet Manager failover, AMRs take 1 to 3 minutes to reconnect and resume.
