What is MikroTik SXT LTE6 kit SXTR&FG621-EA?
The MikroTik SXT LTE6 kit, part number SXTR&FG621-EA, is a powerful outdoor LTE CPE (Customer Premises Equipment) that combines a high-gain directional antenna with a built-in LTE modem. It supports LTE Category 6, which means it can aggregate two bands simultaneously for faster and more stable connectivity. Equipped with a 17 dBi antenna, it offers impressive signal reception, even in remote or low-signal areas.
One of the standout features of this unit is its integrated LTE modem with support for international LTE bands, making it suitable for deployment almost anywhere in the world. The SXTR&FG621-EA version is optimized for Europe, the Middle East, and parts of Asia, with support for key LTE frequency bands including 1, 3, 5, 7, 8, 20, 38, and 40. The enclosure is built for outdoor mounting and can withstand extreme weather conditions, with operating temperature tolerance from -40°C to +60°C.
Versatile and Intelligent LTE Solution for Demanding Environments
What truly sets the MikroTik SXT LTE6 kit SXTR&FG621-EA apart is its intelligent design. It’s not just a modem — it’s a full-featured RouterOS-based device with routing, firewall, NAT, DHCP, VPN, and monitoring features built-in. That means you can use it as a standalone LTE router without needing an additional device to manage your network. Whether you’re setting up rural internet for a farmhouse, construction site, marine environment, or temporary event, this kit ensures fast setup and uninterrupted service.
The unit includes a mounting bracket and a 24V power adapter with a passive PoE injector, allowing you to power the device over a single Ethernet cable. With its sleek, compact, and weatherproof design, the SXT LTE6 is an all-in-one solution for outdoor connectivity challenges.
Applications: Where Can You Use MikroTik SXT LTE6 kit?
The MikroTik SXT LTE6 kit SXTR&FG621-EA is ideal for:
- Rural homes and farms with poor DSL or fiber coverage
- Mobile offices or construction sites that move frequently
- Backup connectivity for business continuity in case of wired internet failure
- Maritime or oilfield installations requiring stable outdoor LTE access
- Surveillance setups needing remote LTE-based connectivity
- Events or festivals in outdoor or temporary locations
Its ease of deployment and compatibility with global LTE bands make it a popular choice among ISPs and system integrators.
Port Configuration and Connectivity Options
The SXT LTE6 kit is designed to be compact and efficient, featuring:
- 1 x 10/100 Ethernet port with Passive PoE-in support
- Nano SIM slot with easy access
- PoE injector included in the package
- MicroUSB type AB port for console access (debugging/monitoring)
While minimal in physical interfaces, its performance is optimized for dedicated LTE-to-LAN use cases.
Build Quality and Reliability
This device is built for resilience. The body is made from durable plastic designed to withstand UV exposure and water ingress. It is certified for outdoor usage and can handle temperature extremes that many competitors cannot. The pole mounting kit included in the box ensures secure installation even in high wind conditions.
The antenna itself delivers up to 17 dBi of gain, which is significant in extending LTE signal reach and stability. The internal modem’s Cat 6 capabilities allow theoretical speeds of up to 300 Mbps download and 50 Mbps upload — although actual performance depends on signal quality and ISP capacity.
Failover Internet for Businesses
If you’re managing a branch office or retail outlet that relies heavily on constant connectivity, you can install the MikroTik SXT LTE6 kit as a backup link. In case the primary fiber or DSL line fails, RouterOS will automatically switch to LTE to maintain uptime — no manual intervention needed.
Reliable Internet for CCTV Monitoring
Many surveillance projects operate in remote areas or outdoor compounds where wired internet is unavailable. This device serves as the perfect backbone for a reliable, long-range LTE uplink to power your NVRs or IP cameras. Its high-gain antenna ensures even low-signal zones are connected consistently.
