Serbian regulator RATEL opens auction for 470–694 MHz UHF band

Serbian regulator RATEL has opened an auction for frequencies in the 470–694 MHz UHF band, putting roughly 224 MHz of spectrum historically occupied by terrestrial television into contention for new wireless uses.

What is RATEL auctioning?

The Regulatory Agency for Electronic Communications and Postal Services has posted an auction notice inviting operators to apply for licences in spectrum sitting just below Europe's long-cleared 700 MHz digital-dividend band. The agency has not yet published reserve prices, licence durations or a bidding-round timetable in the public material available so far.

The lot covers the lower UHF range from 470 MHz to 694 MHz — adjacent to the 700 MHz block that European countries reallocated to mobile broadband a decade ago and that now hosts LTE and 5G services across much of the continent.

Why the band draws operator interest

Across Europe, the 470–694 MHz range has spent years caught between broadcasting incumbents and mobile operators drawn to the band's favourable propagation. One low-band site can blanket villages, motorways and indoor spaces that mid-band 5G reaches only through dense, costly tower grids.

France, Germany and the United Kingdom have preserved most of the band for digital terrestrial television. The United States cleared 614–698 MHz for cellular use through its 2017 incentive auction — a path several markets have watched closely without copying. Each outcome reflects a different read of how much spectrum broadcasting will need in a streaming-first decade.

Serbia's three main mobile operators — state-owned Telekom Srbija (branded mts), Yettel (the successor to Telenor Serbia under PPF Group) and A1 Serbia (formerly VIP) — already run commercial 5G networks built on earlier spectrum awards and would likely treat any new low-band allocation as a coverage extension rather than a capacity boost.

The trade-offs operators will weigh

The technical appeal of sub-700 MHz is well known: signals at these frequencies bend around terrain and penetrate walls far more reliably than 3.5 GHz 5G, making the band efficient coverage spectrum for rural roads, indoor use and long industrial corridors.

The trade-off sits in the equipment base. Handsets and base stations tuned to the full 470–694 MHz block fall inside a narrower global market than the 700 MHz equipment pool built out over the past decade. Operators will price that gap into any business case.

Incumbents further complicate the picture. Terrestrial broadcasters and wireless microphones already operate in portions of the band, and any reallocation will require a path for clearing or sharing those users before new mobile licences go live. France's repeated decisions to keep its block anchored to broadcasting show how political and cultural weight can outweigh pure spectral efficiency.

What happens next

Serbia holds EU candidate status, and its spectrum policy is regularly reviewed against the bloc's electronic communications framework. How RATEL frames the auction — as additional mobile capacity, broadcast downlinks, programme-making spectrum or a shared band — will shape the kind of bids that arrive.

RATEL's announcement invites applications through its website without specifying a closing date in the public notice. The next public step, publication of the detailed information memorandum, will tell operators whether licences carry coverage obligations, deployment deadlines or technology-neutral terms.

Until reserve prices, lot structure and timelines are released, the auction remains more a question than a transaction. The outcome will set the course for how Serbia fills out its low-band spectrum map in the second half of this decade.
