T-Mobile's 5G network capacity gained with MU-MIMO

T-Mobile's 5G network capacity gained with MU-MIMO

SRG analysts conducted tests of T-Mobile's 2.5 GHz network in Southern California, where Ericsson is the infrastructure supplier. Their conclusions show a significant capacity increase (over 50%) in the presence of MU-MIMO compared to single-user MIMO, also known as SU-MIMO. This is especially relevant for his Fixed Wireless Access (FWA) business at T-Mobile. For SRG`s tests, T-Mobile furnished logistical assist, consisting of phones, SIMs and steering on wherein to discover a massive cluster of cells helping MU-MIMO with 10 Gbps backhaul. Neither T-Mobile nor Ericsson furnished economic assist for the study. The analysts used industrial smartphones OnePlus 10 Pro and the Samsung Galaxy S22, in addition to pre-industrial CPEs from Arcadyan. Spirent Communications and Accuver Americas furnished take a look at and size tools. SRG President and founder Mike Thelander said his company gave T-Mobile and Ericsson a brief presentation ahead of the report's release, noting that T-Mobile has MU-MIMO capabilities nationwide. , revealed that the Sounding Reference Signal (SRS) Technology is implemented. I am using Ericsson equipment. There are plans to roll out similar functionality on Nokia 2.5GHz sites by mid-2023. He pointed out that not all smartphones support his SRS, but SRG believes the feature is present on the carrier FWA CPE and at least on certain of his iPhone models. Last year, Thelander encountered MU-MIMO in the Verizon band n77 (C-band) Ericsson network in Minneapolis. Verizon confirmed to SRG that it is evaluating the technology, Thelander said. “There’s clearly interest from all operators. I don’t know where Verizon’s at in terms of deploying it” or testing it, he said. Both T-Mobile and Verizon use Ericsson and Nokia 5G gear; Verizon also uses Samsung.  “If an operator can increase their network capacity by 50% through a basic software upgrade, that’s a no brainer,” he said. “That’s why it’s so compelling.” There are different ways of implementing MU-MIMO. What Ericsson is doing is based on technology called SRS and Thelander equated it to a game of Marco Polo in a swimming pool. “This is a similar concept whereby the phone is transmitting signals in the uplink. Those signals allow the base station to figure out where that mobile phone is,” and it can precisely send data to it and use the same resource block to send data to another phone, he said. It works best in a low-mobility situation, which is where FWA operates. SRG included some insights based on its observations while testing and analyzing the study results that are unrelated to MU-MIMO. “The Reader’s Digest version is that T-Mobile is currently evaluating a new configuration for its TDD frame structure which will allow it to increase downlink capacity/downlink data speeds,” the report notes. Thelander also explained the meaning behind the illustration on the cover of the MU-MIMO report. It shows a Spider-Man character shooting signal beams aimed at Doctor Octopus, who has four “arms” and each one is holding a phone. Two beams of light are coming from the base station to each phone, and these beams represent data streams, tallying up to eight. With SU-MIMO, each network resource can be re-used up to four times. The terms “4x4 MIMO” and “4-layer MIMO” refer to one network resource being re-used four times, and there’s a theoretical quadrupling of the throughput over a single network resource, he said. MU-MIMO is conceptually similar to SU-MIMO, but “the difference is that one network resource can be shared by multiple phones,” he said, theoretically allowing eight phones to share the same network resource at the same time. I added that you can connect to different phones with This effectively doubles the capacity of the network, making capacity critical when it comes to FWA. Both T-Mobile and Verizon claim they are taking steps to ensure that his FWA users, who on average use more data than their cellphone customers, don't run out of capacity. But the question of capacity and how much we can deliver comes up again and again. Especially when there isn't much mid-band 5G spectrum in the pipeline, it's no surprise that carriers are at their disposal to use whatever tools they can to increase capacity. "For things like fixed wireless access, which consumes a lot of data, it's a great way for operators to increase the overall capacity of their networks," said Thelander.

CNA file photo Taipei, Jan. 18 (CNA) The data transmission speed of 6G (sixth-generation wireless) networks is expected to be 10-100 times faster than current 5G technology, MediaTek Inc., one of the world's leading chip design companies, said in its 6G vision white paper released Tuesday. According to the report, the initial 6G standardization effort  is expected to start in 2024-2025, with the initial standard technology expected around 2027-2028. "Our 6G vision is of an adaptive, integrated and super-heterogeneous wireless communication system, delivering pervasive mobile connectivity in a truly ubiquitous manner," the company said in the white paper. Currently, 6G is at the stage in which the industry is making breakthroughs in key technologies research and development, said Fan Ming-xi (范明熙), deputy general manager of MediaTek's communication system design department. MediaTek is increasing its research and development in the field and is working with top-end professionals in the academic and industry research sectors to explore innovative technology trends, Fan added. In addition to several new technologies such as ultra-wideband receiver and transmitter technology, the convergence of terrestrial and non-terrestrial networks, artificial intelligence, and machine learning for networking and communications could lead to more innovative and emerging technologies being rolled out over the next few years, according to Fan. MediaTek said that 6G standardization and roll-out will follow the timeline set out in the International Telecommunication Union Radiocommunication Sector's (ITU-R's) International Mobile Telecommunications (IMT) vision for 2030 and beyond. The company said it will continue its efforts in 5G development to help further push the standardization and commercialization of 6G systems. It also outlined new killer applications for the 6G era, saying these apps will drive the need for more performance, such as extreme holographic and tactile communications, digital twins, advanced telepresence etc. MediaTek said that 6G technology could lead data transmission speed to increase by a factor of 10-100 with guaranteed low latency relative to 5G, and provide additional spectrum availability in 7-24GHz and sub-THz frequencies, with total addressable bandwidth of 50GHz. This new spectrum opens up a significant opportunity for service delivery of extreme applications, but also creates significant challenges to overcome poor propagation at higher frequencies, according to the report.

Jio, Airtel, Vodafone Idea want 5Gi to be merged with 3GPP standard; urge India to maintain technology neutral stance

Jio, Airtel, Vodafone Idea want 5Gi to be merged with 3GPP standard; urge India to maintain technology neutral stance

Telcos through their representative body COAI said that making 5Gi a partof 3GPP standard or global 5G standard can ensure early adoption byoperators without any policy intervention and all stakeholders can reap thebenefits of economies of scale.   NEW DELHI: Indian telecom operators --Reliance Jio, Bharti Airtel and Vodafone Idea -- have yet again dialled the Indian government urging it to continue with its its technology neutral approach for the adoption of 5G technology and suggested that efforts can be made for global harmonization of 5Gi standards by making it part of 3GPP.Telcos through their representative body COAI said that making 5Gi a part of 3GPP standard or global 5G standard can ensure early adoption by operators without any policy intervention and all stakeholders can reap the benefits of economies of scale. The COAI’s letter to the DoT secretary coincides with the department’s move to form a committee to devise a strategy for commercialization and monetisation of 5G and domestically developed 5Gi technologies. The Telecommunication Engineering Center (TEC) is currently goingthrough public consultations on 3GPP Rel-15 and 5Gi standards.“With regard to the adoption of 5Gi, it is to be noted that the ecosystem forthis is yet to be developed, validated & fully tested. Even if the telcos wantto test the 5Gi standard during the on-going trials, this is not possible as no devices for this standard are available. You would appreciate thatvendors work on the principle of economies of scale for development ofequipment,” Lt. Gen Dr. SP Kochhar, Director General of COAI said in aletter to telecom secretary, K. Rajaraman.The Cellular Operators Association of India (COAI) represents RelianceJio, Bharti Airtel and Vodafone Idea along with telecom vendors like Nokiaand Ericsson.Kochhar reiterated that chipsets for 5Gi are yet to be developed and evenif vendors agree to develop chipsets for 5Gi, it will take around 1-3 yearsto develop them and that too at a very high cost as these will be used onlyin India given that the standard is not globally harmonized, hence not “This may put the consumer at a burden if sufficient options are notavailable for device procurement as also the operators will have toundergo additional constraints in validating technologies that areuncommon,” he said.COAI said that mandating a technology/ standard for rural, that relies onhigher cost devices and additional capex investments would not be notjustified, especially when an existing affordable globally harmonizedtechnology solves the same problem/ provides better results.During the ongoing 5G trials, Bharti Airtel and Ericsson demonstrated athroughput of 200 Mbps at an inter-site distance of 20 kms in ruralscenarios using 3GPP compliant network elements and user terminals. “This far exceeds the claimed throughput of 18 Mbps with 12 kms inter-sitedistance by 5Gi, which is only through a simulated test as no field trialscould be conducted using 5Gi,” Kochhar said.The body said that its members are also supportive of India centricapproach to innovation and want the 5Gi standard to be available to themfor consideration for adoption only when it is "interoperable, implementableand has benefits for entire Indian 5G networks."“Hence, it is necessary to have global harmonization of 5Gi standardsspecifications. We recommend efforts towards making the solutioncomponents of 5Gi part of 3GPP, especially since the variation in thisversus the globally harmonized standards specification would have adirect impact on making the specifications viable for commercialdeployment without fragmenting the ecosystem,” Kocchar said. COAI argued that India’s technology neutral approach has helped operators to deploy any of the available globally harmonized technologies, thereby making services affordable by driving down the cost of network and devices. Globally harmonized standards benefits Indian consumers by providing “world class affordable” services. “ Therefore, principally, National Standards for India should be globally harmonized and leverage global economies of scale both for network & smartphones,” COAI said, adding that standards must enable international roaming & interoperability across networks deployed globally and must also enable ready to use ecosystems of both networks and smartphones.
