For all those who are interested in the 5G auction, CNI presents some statistical data derived from the auction results published by the BNetzA. The statistics show first of all the progress of the bids and the sum of the frequency blocks associated to each bidding party. In addition to that the cost per frequency spectrum (in Euro/Hz) is calculated as well as the split of the frequency spectrum and its associated cost. Based on the data, one can easily identify different phases of the auction (see below). After 3 months duration and almost 500 rounds the auction finally ended with a total of 6,550 Mio. Euro. The final outcome shows that the bidders associated with average bids of around 20 Euro/Hz more value to the 2 GHz-band compared to the 3,6 GHz-Band (with around 10 Euro/Hz average bid). This is due to the more favourable propagation characteristics of the lower frequency: the same coverage can be achieved with less base stations. The analysis has been originally prepared for the lectures "Mobile Radio Networks" and "Business Economics of Information & Communication Technologies". The discussion of the German 5G auction serves as a vivid and timely case study to demonstrate the close and complex interdependencies of technology and economics.

A more detailed analysis of the course of the auction is depicted below:

After approx. 180 rounds the bids and association of the 2 GHz range stabilized with 4 frequency blocks allocated to Telekom and Vodafone, while Telefonica and 1und1 Drillisch each provided for 2 blocks the highest bids. The 2 GHz blocks with earlier availability received each bids in the 210 Mio. Euro range, while the bids for those blocks available in 2026 raised around 170 Mio. Euro each. The bids for the 3.6 GHz blocks were at this stage still in the 100 Mio. Euro range.

From round 180 onwards, the bidders focussed primarily on the 3.6 GHz range and raised their bids in small steps (2% minimum increment according to the rules of the auction). Then in round 227 1und1 Drillisch raised their bids for 6 blocks significantly to in the 125 Mio Euro range, while all other bidders continued in small steps on a much lower basis (around 105 Mio Euro at this stage of the auction). A phase of rather slowly growing bids followed: while the higher bids from 1und1 Drillisch lead to a constant allocation of 6 blocks (indicated by the green lines) the three remaining bidders were not satisfied with the allocation of the 3.6 GHz blocks and continued to raise their bids gradually. During this phase typically only one block changed its allocation to another bidder.

This phase was only interrupted when in round 318 1und1 Drillisch withdrew its high bids. Yet as no other bidder jumped in, 1und1 Drillisch renewed its bids in round 324 and the auction continued steadily.

Two weeks later with round 427 the bids of all bidders reached the same level and the formerly static allocation of six blocks ended. Because the auction still continued in small steps, the BNetzA decided from round 466 onwards to raise the minimum increment significantly (from approx. 3 Mio to 13 Mio. Euro) in order to speed up the auction. Only after 30 additional rounds the auction finally ended with a total of 6,550 Mio. Euro. The final outcome shows that the bidders associated with average bids of around 20 Euro/Hz around 30% more value to the 2 GHz-band compared to the 3.6 GHz-Band (with around 15 Euro/Hz average bid).
