The first 5G call is made on AT & T’s C-spectrum


The first 5G call is made on AT & T's C-spectrum

The acquisition of T-Mobile by Sprint was a great move by the operator as it allowed the upstream wireless service provider to manage Sprint’s mid-band 2.5 GHz frequencies. The use of mid-band frequencies is key to T-Mobile’s 5G layer cake system, which starts with a 600 MHz low-bandwave that travels long distances but produces 5G speeds that are not much faster than 4G. At the opposite end of the spectrum is a very fast high-bandwidth mmWave spectrum with signals that are limited in distance and easily blocked by structures.

AT&T and Nokia successfully combine operator’s first test call on C-band mid-range frequencies

The solution is to use a mid-spectrum that is faster than low-bandwidth but not as fast as mmWave and covers more distances than mmWave, but not as much as low-bandwidth. And that’s what T-Mobile delivers the midband spectrum it received from Sprint. Some analysts believe its mid-band shares will help T-Mobile become the fastest 5G provider in the country thanks to the three-layer cake.

So what stops AT&T and Verizon from copying T-Mobile? The amount of center frequency spectrum available in cellular networks is limited, but the FCC recently auctioned 280 MHz of the C-band spectrum in the 3.7-3.98 GHz band. Verizon spent $ 45.4 billion on profit offers offered by AT&T for $ 23.4 billion and T-Mobile for only $ 9.3 billion.
But not all C-bands are the same as T-Mobile CEO Mike Sievert said several months ago when he said that “the truth is that the C-band is best for urban areas because it does not spread as well as T-Mobile’s significant current mid-band frequencies. Band C makes the great story even better, and we’re incredibly pleased with the clear success of this auction. Our competitors had no choice but to go all-in-break-the-bank to stay relevant in the 5G era. ”
AT&T announced last week that it, along with Nokia, had successfully made its first call on AT & T’s C-spectrum using a 5G-compatible device in a smartphone-like shape. The latter is the power supply by Qualcomm’s Snapdragon X55 5G modem RF system. Nokia AirScale baseband and 5G massive MIMO C-Band radio (with a lot of connections from the radio to the device) was also introduced in the test.

The country’s third-largest operator, by the end of 2023, AT&T hopes to cover 200 million people with C-band signals that beat Verizon’s announced schedule. In March, AT&T and Nokia signed a five-year agreement that will allow the operator to cover the U.S. in Nokia’s C-band. Last year, Nokia became the first 5G vendor to use C-band to successfully run the experiment in the states.

AT&T hopes to enable 5G C-band calls for subscribers later this year

Paritosh Rai, who oversees AT & T’s 5G project management office, said, “Bringing 5G innovations to market is very important to our teams. Working on these C-band field test requests gave us the feeling of“ Let’s make history again! “” Later this year, AT&T is expected to click a switch that will make C-band signals available to AT & T’s first batch of 5G customers.

Tony Seyfried, Director of Technical Editors at AT&T, says, “The C-band, or spectrum, allows our 5G network to reach its full potential – giving our customers the connection they want faster and better.” Seyfried added that “This type of project is really eager to implement because if you succeed, you will be at the forefront edge technology – not just for AT&T or our customers, but for the industry as a whole. “
