T-Mobile’s 5G Home Internet Is Getting Better With New Modems





T-Mobile is gearing up to launch two new home internet devices this year – The Arcadyan TMOG4AR and the Sercomm TMOG4SE. Each is building off of its predecessor modem models, these new upgraded versions hopefully will provide users with more reliable connections and faster speeds, even with a weaker connection.

The Arcadyan TMOG4AR is an upgrade from the KVD21 model and supports limited carrier aggregation to bring faster speeds in heavy internet traffic areas. There’s no word yet on whether the Sercomm TMOG4SE modem will offer carrier aggregation. 

This model will have nine cellular antennas and five WiFi antennas, compared to previous models topping out at four. The Sercomm TMOG4SE modem will offer nine cellular antennas as well. 

Unlike the Arcadyan TMOG4AR modem, the Sercomm TMOG4SE modem will offer external antenna support which should work with all supported bands, which is great news for those living in rural or high-traffic locations who want an even stronger signal.

Both of the upcoming models could improve hardware and cellular functionality. They could offer LTE bands 2, 4, 5, 12, 25, 48, 66, and 71. For 5G bands, they likely will support 25, 41, 48, 66, 71, and 77.

Reports show “it looks like the TMOG4AR will be able to aggregate two LTE band 2 or two LTE band 48 connections at up to 20MHz of bandwidth each. For 5G, band 41 should be able to support two connections at 100MHz and 80MHz each.” If there is a dual LTE-5G connection, a total bandwidth connection of 220HMz is possible.

The new T-Mobile models are still undergoing FCC testing but depending on if the company decides to use all available features, we should see the modems roll out sometime this year. The Arcadyan TMOG4AR has a tentative launch date of August 22nd, 2023. The Sercomm TMOG4SE is looking at an October 12th release date and will likely be only available for businesses.
