5G SA in your pocket — 31 devices, bands you lock on site
LC581 runs 5G SA standalone, with 19 Sub-6GHz bands across major markets and 2.3 Gbps peak downlink. The on-screen menu opens directly — an engineer locks bands standing at the device instead of going back to a laptop.

Four things that decide it
Lock bands on site
The on-device menu goes straight to band lock, pinning the unit to a chosen band so nearby cells cannot pull it onto a neighbour frequency. Field tuning without a laptop and without remote access.
31 devices at once
Wi-Fi 6 dual band, 2.4 GHz at 600 Mbps and 5 GHz at 1200 Mbps, 2×2 MIMO with OFDMA and MU-MIMO. One unit covers a small crew or a temporary command point.
5G SA and 4G dual mode
Standalone 5G as the primary mode, with 4G LTE fallback and 22 LTE bands kept in the radio. Where SA coverage ends, the link keeps working — no second device needed.
The screen is the console
The round colour display carries network info, network mode and band lock. There are no indicator lights to read, and no need to join the Wi-Fi before changing settings.

Where it fits
Field engineering and drive tests
Band lock pins the unit to one band so cell handovers do not interrupt sampling.
Temporary office and response
An 8000 mAh battery plus 31 concurrent clients: one unit carries a temporary command post or a repair crew without hunting for a socket first.
Cross-border travel and small teams
19 5G bands cover Southeast Asia and major market frequencies — swap the SIM and it works, whatever the operator.
Questions we actually get
Does it support 5G NSA?
No. LC581 is a 5G SA standalone device; where SA is not available it works in 4G LTE dual mode. If your operator network requires NSA, tell us in advance and we will match a different model.
Battery capacity and runtime?
Built-in 8000 mAh. Runtime varies a lot with the radio mode, Wi-Fi load and signal strength, so measured per-scenario figures go into the full datasheet instead of one vague headline number.
Can bands be locked, on the device or remotely?
On the device. The on-screen menu opens band lock directly — no laptop and no remote back end. This is the single feature customers ask about most.
