en.Wedoany.com Reported - This week, the pace of mobile network expansion in Germany slowed, with varying progress from Deutsche Telekom, Vodafone, o2-Telefónica, and 1&1. Deutsche Telekom's subsidiary, Deutsche Funkturm (DFMG), has initiated the construction of a new batch of base stations. These stations are typically equipped with Deutsche Telekom equipment first and can later be leased by other operators. Vodafone focused solely on maintenance and upgrades at various sites this week, with relevant stations shut down during construction, potentially causing network outages or weak signals for users in those areas.

For o2-Telefónica, its expansion partner American Tower (ATC) has built some base stations, which will gradually be equipped with technical equipment. o2 is also filling gray areas (where other operators have signals) or white areas (where no operator has signals) and continuing the 5G (n28 band) upgrade. In North Rhine-Westphalia, a transmission tower in Plettenberg (Märkischer Kreis), built by Phoenix Towers and funded by the Mobile Communications Infrastructure Company (Mobilfunk-Infrastruktur Gesellschaft, MIG), was inaugurated. Deutsche Telekom, Vodafone, and o2-Telefónica all transmit signals from this tower. In Cuxhaven, Lower Saxony, a 1&1 mobile communications site is under construction, with the specific operational date yet to be announced.
