Portable 5G SA router LC581 19 Sub-6GHz bands, 31 devices, band lock straight from the screen

A pocket device for projects that need 5G SA independent of operator-supplied equipment: 19 Sub-6GHz bands, up to 2.3 Gbps, dual-band Wi-Fi 6 and 31 concurrent clients. The menu opens on the device screen — an engineer locks bands standing at the device, without a laptop and without a remote platform.

Model

Portable 5G SA router

5G SA · Release 17

19 Sub-6GHz bands · 31 clients · band lock on the screen

The menu opens on the screen, not in a web UI: the device has no mandatory cloud binding, and configuration needs no laptop. For field work that matters more than another hundred megabits on the datasheet.

Two shells, one platform

LC580 and LC581 — same inside, different body

LC581 is the round-display version in grey-green. Electrically it is identical to the LC580 (square touch screen, silver-grey and red finishes): the same 19 Sub-6GHz bands, the same Wi-Fi 6, the same 8000 mAh battery. Choosing between them is a matter of looks and ergonomics; the specification is shared.

Before you order

On 5G bands in Russia

LC581 is a 5G SA (standalone) device with no NSA mode. It brings up 5G only where the operator runs a full SA network. Russia has no commercial 5G SA networks yet: operators run LTE and 5G frequencies have been allocated on a limited, trial basis.

If the project is in RussiaLC581 is used as a 4G LTE device: 22 LTE bands, Wi-Fi 6, 31 clients. The headroom for 5G SA stays for later — you will not have to replace the model once the network arrives.

If the project is in Asia or the Middle EastViettel and a number of Southeast Asian operators already run SA. There LC581 works on 5G, which is its primary scenario.

If you need 5G todayTell us the bands and the operator in the project. We will match a model to that network, or take the stationary LC550 CPE. We will not sell a device that demonstrably cannot attach.

What it solves

Four reasons people actually buy it

Band lock on siteThe on-screen menu leads straight to band lock: the unit is pinned to a chosen band and neighbouring cells cannot pull it onto an adjacent frequency. Field configuration without a laptop and without remote access.

31 devices at onceDual-band Wi-Fi 6 with OFDMA and MU-MIMO. One unit covers a small crew or a temporary command post.

5G SA and 4G LTESA is the primary mode; 22 LTE bands stay in the radio. Where SA coverage ends the link continues, with no second device.

The screen is the consoleNetwork info, network mode and band lock live on the device screen. No indicator lights to read, and no need to join the Wi-Fi before changing settings.

Where it is used

Three typical scenarios

Field work and measurementsBand lock holds the device on one frequency so cell handovers do not interrupt data capture.

Temporary office and response31 clients — one router covers a temporary post or a repair crew without deploying a fixed line.

Travel and small teams19 5G bands and 22 LTE bands cover major market frequencies: swap the SIM and it works on any operator.

Questions

What customers ask before ordering

Does it support 5G NSA?

No. LC581 is a 5G SA (standalone) device with no NSA mode. Where there is no SA network it runs on 4G LTE: 22 LTE bands stay in the radio. If your operator runs NSA only, tell us in advance and we will match a different model.

Will it work on 5G in Russia?

No — Russia has no commercial 5G SA networks yet. In Russian projects LC581 is used as a 4G LTE device with headroom for 5G SA later. If the project needs 5G today, send the operator and bands and we will match a model to that network.

What are the battery capacity and runtime?

Built-in 8000 mAh. Runtime varies a lot with the radio mode, Wi-Fi load and signal strength, so the datasheet gives measured figures per scenario instead of one vague headline number.

Is band lock on the device or via a platform?

On the device. Band lock is configured directly on the device screen: no laptop, no remote platform. For field work that is the whole point.

Can I order a batch, and how is the price calculated?

Price is calculated by batch and delivery terms, not by a single line from a public price list — we do not keep a public price list. Send the quantity and destination city and we reply with a calculation within one business day.

Next step

First we check the bands against your operator

Send the country, the operator and the frequency plan. We reply with a mapping table: which bands work, where it falls back to 4G, and attach the full datasheet. If the model does not fit your network we say so before you order anything.
