T-Mobile US has conducted a 5G network trial using its millimeter-wave (mmWave) spectrum that could allow the carrier to increase the speed and capacity of its expanding Constant Wireless Access (FWA) service.
The test, conducted with partners Ericsson and Qualcomm, used the operator’s 5G standalone network (SA) to package 8 channels of mmWave spectrum that produced peak download speeds in excess of 4. 3 Gbps. It also connected 4 channels of the mmWave spectrum in the uplink. , generating speeds in excess of 420 Mbps.
Uplink speeds in wireless networks are slower than downlink speeds. This is maximum due to the power requirements required to transmit a high-spectrum density connection between a device and a base station. Most end-user devices are smaller in shape than a cell tower. , so they want a more artistic generation of antennas to help the signal. The devices also rely on a built-in battery, which can temporarily heat up and drain as you seek to force that connection.
Lacheck’s speed ratings surpass recent checks conducted through T-Mobile US in its mid- and low-band spectrums. This included a verification this summer in which it used channel aggregation from four operators to mix spectrum from its 2. 5 GHz, 1. 9 GHz and 600 MHz. portfolio to produce downlink speeds in excess of 3 Gbps.
T-Mobile US noted that the 5G mmWave trials are intended for deployments in “high-traffic spaces such as stadiums and, potentially, for consistent wireless service. “The last component would be T-Mobile US’s Wireless Broadband Internet (HSI) service. .
“We’ve always said we’ll use millimeter wave where it makes sense and this test allows us to see how the spectrum can be put to use in different situations like crowded venues or to power things like fixed-wireless access when combined with 5G standalone,” Ulf Ewaldsson, president of technology at T-Mobile US, said in a statement.
This FWA use case may be just one important mmWave pathway for T-Mobile US.
CEO Mike Sievert told an investor conference this week that the carrier has designed its network to support up to 80 gigabytes of usage per month by each customer. However, T-Mobile US EVP and CTO John Saw said during a keynote speech at the recent MWC Las Vegas event that its FWA customers were using around 450 gigabytes of data per month.
The operator controlled for this disparity by analyzing FWA connections to its network. This includes tracking network capacity through the mobile site, which can have an effect on the ability of new customers to subscribe to the service on a daily basis.
“If another 3 people from your community sign up, or 4 or five more people depending on the area, the entire community will be removed from our list until we have that excess capacity again,” Sievert said in the past.
T-Mobile US ended the third quarter with 4.2 million FWA connections on its network, which was more than half-way toward its stated goal of being able to support around 8 million total FWA customers using its current network architecture and spectrum holdings. Those FWA customers have basically been gravy for the carrier as they provide an ongoing revenue stream without needing the carrier to invest any more capex into its network.
Ewaldsson said on the operator’s second-quarter earnings conference call that it has deployed mmWave spectrum in select markets, particularly in Manhattan and Los Angeles, “where we have this ordinary need for capacity. “more in a macrospectrum strategy based on its mid- and low-band assets, “millimeter wave can also potentially be an attractive game for us when it comes to improving the features that can be used,” for example, for HSI.
“And we are working with our vendors, and we are working through our OEMs to figure out if we can make a viable economic and technical performance case out of that with them,” Ewaldsson added.
The use of mmWave spectrum can allow the operator to increase its FWA capacity potential, adding greater penetration into the enterprise sector.
Mishka Dehgan, senior vice president of strategy, product engineering and responses for T-Mobile’s business group, told SDxCentral in an interview at MWC Las Vegas that the operator sees opportunities for FWA’s business growth, highlighting an express business need.
“Usually what you see with the constant wireless connection is a nationally distributed footprint that the visitor needs to illuminate,” Dehagan said.
Dehgan also highlighted T-Mobile US’s recent expansion of its enterprise-grade FWA device partnerships with Cisco and Cradlepoint.
Sievert said this week that the operator is looking at features to bolster its FWA functions “both in terms of millimeter wave and small cells, as well as maybe mid-band, but with standards-based or non-standards-based technologies, all of that. I’m watching. They are different from each other and we have not yet drawn any conclusions.
Although the lacheck mmWave check includes a collaboration with vendor partner Ericsson, T-Mobile US remains an advantage over its other leading 5G infrastructure provider, Nokia. This is vital as Nokia lost a significant percentage of the market in AT this week.
“We price our partnerships with Nokia and Ericsson and consider it a merit to be able to buy from the most sensible to the last from multiple partners,” Sievert said at the investor conference. “We also think it is very smart that the global West has two global leaders in this field. Therefore, we are very happy with our relationships and greatly appreciate the deep partnerships we have with Ericsson and Nokia.
