German mobile spectrum auction bids totaled EUR3.25 billion on day 23. It is up from EUR3.19 billion the day before.

According to German network regulator Bundesnetzagentur and analysts, proceeds from the entire auction could reach up to EUR8 billion. Total bids are still far away from it. 

Auction isn't open to all mobile operators. Germany's federal network regular admitted only Vodafone, T-Mobile, E-Plus, and O2 to the bidding.

The four operators are bidding in frequency auctions in the ranges 800 MHz, 1.8 GHz, 2 GHz and 2.6 GHz. The regulator is offering a total of 41 frequency blocks across the four frequency bands, which are expected to be used for LTE network deployments.
