28 GHz band: Qualcomm builds with partners 5G millimeter wave network in Moscow


Qualcomm will work with a government agency for information technologies in Moscow, Russian mobile operators and equipment and software vendors on a 5G millimeter-wave network. Like the US company on August 14, 2019 announced, the first network of this kind in Europe is scheduled to start in autumn 2019. The 5G New Radio (NR) mmWave network in the band n257 is designed to provide improved fixed and mobile access for home users and businesses.

The network operators MTS, Vimpelcom (Beeline), Megafon or Tele2 are active in Moscow.

"Moscow plans to equip business centers, stadiums, main roads, convention halls, train stations and airports with high-speed, high-capacity, low-latency mobile communications over the next few years, and we're working with manufacturers to bring 5G mmWave technology to a wide range of devices from smartphones to fixed wireless access points. "said Yulia Klebanova, Vice President Business Development, Qualcomm Europe.

The 28 GHz band is the most widely tested 5G band in the world. The expansion of the 28 GHz band is described in 3GPP TR 38.815. Like all millimeter-wave bands, n257 is a capacity layer designed for short-range transmission at high data rates. Of the available mmWave bands, the 28GHz range is available in the largest number of countries worldwide.

With increasing frequency, the range decreases, but it also increases the achievable data transfer rate. 10G to 20Gbps 5G networks would be possible with channel bandwidths from 100 MHz in the 24 to 86 GHz range. However, these frequency ranges would require a large number of antenna sites.
