Telecommunication operators Three and Vodafone are closing the gap on UK incumbent EE according to analysis conducted by Root-Metrics. The company carried out 646,230 tests across all of the United Kingdom. It assessed the operators in six categories, which ranged from reliability, speed, data, calls, texts and overall performance.
Whilst EE still came out on top as the strongest performer, it was highlighted that both Vodafone and Three had closed the gap considerably. EE was given four awards by Root-Score, while both Three and Vodafone received two awards each.
EE won the best overall category, and also emerged as frontrunners in speed and data. In addition to this, it shared joint-first with Vodafone for text messaging. Three won outright across the UK for its reliability, and shared joint-first with Vodafone for call performance. O2 came last in all categories apart from text quality, where it finished third.
However, this represents a significant and telling change across the telecommunications landscape, last year EE won all the awards on offer by Root-Score. The latest findings declared that whilst EE is the best-performing telco overall in the UK, Vodafone was No.1 in Northern Ireland, whilst Three dominated in Scotland and Wales. Northern Ireland was the only region were 02 performed well.
General Manager of Europe for Root-Metrics, Scott Stonham, suggests that “the report only serves to reiterate just how competitive the UK telecommunications sector is,” he said.
“These latest results have really shaken things up and show the increasing competitiveness in the UK, particularly over the last six months. EE continues to lead the way, but Three and Vodafone are close behind. What is clear is that each operator showed strong performance in at least one particular country, while nobody was able to sweep the board at the four nation’s level. UK consumers have strong mobile options depending on how and where they use their devices most.”
A Senior Research Director on telecoms at HIS Markit said it was imperative that operators needed to invest in radio spectrum in order to succeed. “To succeed, mobile operators must secure sufficient radio spectrum and invest in the necessary equipment, sites and operational teams to ensure consumers enjoy fast reliable mobile broadband. With new UK spectrum allocations soon to be auctioned in the run up to 5G, these performance results provide a snapshot on the competitive balance between the UK mobile operators now, and highlight which operators most need to acquire new spectrum capacity if they are to be a future mobile performance winner.”
Fogg also stressed that the results which come ahead of a spectrum auction in September, could radically alter the balance of spectrum holdings, which would allow operators with smaller holdings such as Three and O2 to compete in a more efficient manner. 02 CEO Mark Evans, has already declared that he wants to see the auction commence soon and that it was compete ‘fiercely’ for spectrum allocation.
ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, announced the company successfully completed tests in seven major scenarios that are part of the second phase of China’s National 5G tests, setting multiple new records for network speeds and performance.
Phase 2 of China’s National 5G tests, organized by IMT-2020 (5G) Promotion Group, were conducted in Huairou in Beijing. ZTE completed tests for continuous wide coverage, eMBB (enhanced mobile broadband) at sub-6Ghz, eMBB at millimeter-wave frequencies, uRLLC (ultra-Reliable and Low Latency Communications), eMTC (massive Machine Type Communications), in addition to two hybrid scenarios, achieving multiple breakthroughs:
- eMBB@Sub6GHz Test: New Record for the Peak Value, with Cell Throughput Exceeding 19 Gbps
In the eMBB@Sub6GHz test scenario, ZTE provided 28 streams for multiple users by using the 3.5 GHz pre-commercial base station, with a peak cell throughput higher than 19 Gbps, a new industry record. This data rate is higher than the ITU-defined value (10 Gbps). ZTE’s solution overcomes the limitations of standard interfaces, and provides more spatial division streams than the standard and common value (16 streams) in the industry. This technology is especially suitable for China's densely-populated urban areas, highlighting ZTE’s technology leadership in 5G eMBB scenarios.
- Industry-first eMBB@mmWave Test: Single-User Rate Exceeding 13 Gbps
ZTE was the first to use the 26GHz base station in the high-frequency eMBB test scenario, and achieved a 4-stream rate of 13 Gbps even when a single test terminal supported a bandwidth of less than 1 GHz. This rate is higher than that defined by ITU (10 Gbps), and is a major step forward in the development and commercialization of high-frequency mobile communications.
- mMTC Scenario: Massive Capacity of 90 Million Connections/MHz/hour/km2
In the mMTC test scenario, ZTE increased the overload rate of connected terminals by 600 percent by using the innovative MUSA (multi-user shared access) technology, and verified an equivalent massive IoT access performance of 90 million connections/MHz/hour/km2, which is 90 times the value (1 million connections/square kilometers) currently defined by ITU. mMTC is one of the three key scenarios defined in 3GPP standards. ZTE plays a leading role in the NOMA (non-orthogonal multiple access) Working Group, serving to accelerate industry standardization of 5G globally.
- uRLLC Scenario: Ultra-Low Latency of 0.416 ms
In the uRLLC test scenario, ZTE achieved an ultra-low latency of 0.416 ms based on a unified test platform, lower than the ITU-defined 1 ms. The system is based on ZTE's self-developed chipsets, which is self-adaptable in eMBB and uRLLC scenarios. The results show ZTE’s leadership in the implementation of key 5G uRLLC technologies and prototypes, which is a key step for 5G commercialization in the future.
- Network Slicing: Unified Solution to Three Scenarios
In the hybrid test scenarios, ZTE created a unified network supporting the air interfaces in eMBB, mMTC, and uRLLC scenarios through network slicing and base stations at sub-6GHz. This achieved flexible configuration of services, allowing a cell to connect a variety of service terminals. Test results showed that the single-cell peak rate reached 15 Gbps, while the air interface latency was lower than 0.416 ms, and the massive connectivity capacity was more than 90 million connections/MHz/hour/km2 at the same time. These three scenarios represent industry breakthroughs in the development for network air interfaces. Through the application of network slicing technology, ZTE simplified the complex network deployment and management, by providing unified air interfaces, bringing flexible and extensive user experience on the future 5G networks.
During the second phase of China’s National 5G tests, ZTE completed verification of its pre-commercial 5G products at sub-6GHz, millimeter wave as well as VCNs, and launched the laboratory and field tests smoothly when interconnecting with the instruments and chips from other manufacturers in the industry. The test results showed that ZTE's products can meet the key performance requirements in seven typical application scenarios, including higher spectral efficiency, greater connection density, higher reliability, and lower latency of air interfaces. ZTE is committed to driving the commercialization of 5G products, laying a solid foundation for commercial 5G deployment in China by 2020.
