Installing an antenna on a rooftop and realizing you forgot a SIM card? Or trying to activate your eSIM, but got stuck in the mobile operator call-center queue, endlessly listening to some classical “Your call is important” melodies over the phone?

MikroTik Connectivity solves both issues! Log in to your MikroTik account, choose a data plan, and you’re online. This pre-activated, self-sufficient eSIM setup bridges the gap between “just installed” and “fully operational.” Ideal for remote locations, failover setups, or any place you need reliable internet right now — without any extra steps.

With a powerful 16 dBi directional antenna, 4x4 MIMO support, 512 MB of RAM, a modern dual-core ARM CPU, and a wide range of supported bands, ATL 5G is built to perform — whether you’re deep in the countryside or surrounded by signal noise in the city. And with Gigabit Ethernet and PoE-in support, installation is cleaner and simpler — just a single cable for both power and data.

ATL 5G features 4 high-gain middle-band antennas and 4 low-band antennas, including full Band 28 support for both LTE and 5G. That means exceptional coverage in all the frequencies that really matter, including from 700 MHz to 1 GHz — the sweet spot for rural reach and wall- penetrating reliability.

These low-frequency bands are some of the most widely used by mobile operators around the world, and ATL 5G is ready to squeeze every last drop of performance from them — ensuring you stay connected where others struggle to get a bar.

And when you don’t want to rely on a traditional SIM card, you can use the MikroTik eSIM as your main data plan for low-usage setups or IoT deployments like KNOTs. Or simply switch profiles and connect to your favorite mobile operator — flexibility is built in.

At first glance, ATL 5G looks like a spaceship — but there’s a good reason for that. This sleek form factor prevents snow and water from collecting and freezing up, making it ideal for installations in cold, wet, or windy environments. No need to climb back up and clean the antenna after every snowstorm.

The IP66-rated enclosure is fully sealed against dust and powerful water jets, so ATL 5G can handle some of the roughest weather conditions — whether it’s mounted on a snowy rooftop in the city or standing alone in the open countryside.

1. All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
2. Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
3. Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
