Nokia and MediaTek announced that they have achieved a world’s first by successfully aggregating 5G Standalone (5G SA) spectrum using 3 Components Carrier (3CC) aggregation. This increases the sub-6Ghz 5G spectrum utilisation by combining 210MHz of FDD and TDD spectrum more efficiently to reach 3.2Gbps peak downlink throughput.

The move will enable communication service providers to deliver higher throughputs and better coverage to more customers, the companies said.

To achieve this performance, Nokia supplied its latest AirScale equipment including its AirScale 5G SA architecture powered by its ReefShark System-on-Chip (SoC) technology as well as its cloud-native 5G core. MediaTek provided its new M80 5G modem which combines mmWave and sub-6 GHz capabilities onto a single chip as well as the user equipment testing platform, the companies explained.

Carrier Aggregation combines frequency bands for higher rates and increased coverage, delivering superior network capacity by maximising the spectral efficiency of 5G networks. Frequency division duplex (FDD) in 600MHz (n71) is a lower frequency band that provides a wide coverage area, improving cell edge performance. Time-division duplex (TDD) in 2600MHz (n41) has higher bandwidth and capacity. The combination of these spectrum bands supports a range of 5G deployment scenarios including indoor as well enhanced outdoor coverage. The high-band sub-6Ghz spectrum bands support high-capacity and extreme mobile broadband capabilities, the companies stated.



MediaTek general manager wireless communication system and partnerships JS Pan said, “This test demonstrates the importance of carrier aggregation in enabling mobile operators around the world to deliver best-in-class speed and capacity to their subscribers.

"The combination of Nokia’s AirScale portfolio and our technology boosts the possibilities of spectrum assets and 5G networks. We look forward to continuing to partner with Nokia to advance the 5G ecosystem.”

Nokia SVP radio access networks Mark Atkinson said, “Nokia continues to drive the 5G ecosystem by delivering new and important innovations. This validation test demonstrates how mobile operators can maximise their spectrum allocations and deliver enhanced coverage and capacity to subscribers.

"Nokia is committed to pushing the boundaries of 5G and delivering industry-leading performance. High-capacity Carrier Aggregation combinations can be achieved in both 5G Standalone (SA) and Non-Standalone (NSA) based on our scalable Airscale Baseband architecture.”

  • Nokia enabling indoor 5G mmWave Fixed Wireless Access
    in 5G

    Nokia announced a claimed Fixed Wireless Access (FWA) breakthrough which could see wireless broadband capacity increase by 5 to 10 times.

    Nokia says its engineers have used a novel approach to make 5G mmWave fixed wireless access viable. Since mmWave requires line-of-sight to operate, signals can easily be disrupted by outdoor or in-home obstacles. Nokia’s 360 High Gain technology, announced on the eve of Broadband World Forum, overcomes the challenge by both amplifying available signals and dynamically finding the strongest connection.

    Fixed Wireless Access broadband devices typically use 4G or 5G mobile signals for high speed home connectivity. Most 5G FWA deployments today leverage low band (sub 2Ghz) or mid band (2-6 Ghz) radio frequencies, but as FWA networks develop, additional spectrum will be needed to drive future growth, Nokia says.

    Operators are now looking to increase speeds by using even more frequencies, notably from the high band spectrum known as mmWave (24 GHz to 40 GHz). However, higher radio frequencies have propagation challenges as they are more likely to be impeded by physical obstacles.

    Nokia says its 360 High Gain 5G mmWave technology captures a 360 mmWave fingerprint of the indoor environment, picks up direct and reflected signals from any direction, and adapts to the changing environment, through advanced analytics.

    {loadposition chris08}

    Mobile Experts principal analyst Kyung Mun said “Fixed Wireless Access is on the rise. It will represent almost $15 billion market cumulatively over the next five years and the mmWave-enabled 5G customer premise equipment will make up 80% by 2026.”

    Nokia president fixed networks Sandy Motley said “Making indoor, self-installable mmWave FWA viable in an urban indoor environment is crucial for FWA growth. The addition of mmWave to the 5G FWA market will deliver the 5 to 10 times more capacity that is needed to support the ever more demanding subscribers and services. I am extremely proud of our Fixed Network team who have notched up yet another technical first”.

    Nokia says it has validated the 360 High Gain 5G mmWave FWA technology in its research labs, and technology trials are ongoing in various urban environments. Volume deployments will start in 2023 and are expected to focus initially on operators with subscribers in dense urban environments where high speeds and high capacity is essential for market penetration, Nokia asserts.

    There is a significant cost in connecting fixed wireless customers, this cost might well be lowered by this Nokia solution. For example the wireless customer terminals installed by NBN and most other fixed wireless operators are external, mounted to facia boards or roof-top poles. Generally an ethernet cable will provide both power and connectivity to an ethernet switch or router that is conveniently installed indoors. The external unit must be engineered to withstand external weather conditions and requires a professional installer to mount and align it to maximise signal strength. In my experience the cost of the CPE and the installation can be upwards of $1,000, so not insignificant.

    The benefit of these external radio units is that they can be positioned to maximise the signal, ensuring that the best possible modulation rates are achieved. The efficiency of the network can be up to 50% improved, compared to the use of indoor self contained terminals. This means less base-stations or less spectrum is needed, especially for low and mid-band spectrum deployments, where spectrum and capacity needs to be carefully managed.

    With mmWave the amount of spectrum that carriers have is multiples of all their low and mid-band spectrum, and the cost paid per MHz is much lower. The need to be spectrally efficient in deployment isn't as prevalent, due to the relatively high bandwidths of spectrum. With that in mind the Nokia solution will reduce the cost of connecting fixed wireless customers, if the cost of the terminals isn't excessive, and the solution can be reliably self-installed.

    For those interested in more technical details, Nokia has a white paper that can be downloaded here.

  • New Honor flagship to use Google apps for international models

    The new flagship smartphone produced by Honor Device, formerly the budget unit of Chinese telecommunications equipment vendor Huawei Technologies, will use Google's proprietary apps for its international models.

    A report in the South China Morning Post said this would be the first time that Honor would include these apps since Huawei sold it to a consortium of 30 dealers and agents, operating under the name Shenzhen Zhixin New Information Technology, for an unspecified sum in November last year.

    The US has targeted Huawei with sanctions for nearly three years now, and among the prohibitions has been the ban on using American products unless the company producing them had permission from the US Department of Commerce.

    When the US placed Huawei on what it calls its Entity List in May 2019, the Chinese firm was unable to obtain Google's proprietary version of Android. The American search giant applied for an exemption to sell the operating system to Huawei but never got it.

    {loadposition sam08}Other companies like Microsoft were able to obtain exemptions from the US administration and thus Huawei has been able to continue using Microsoft's Windows operating system on its line of laptops.

    Honor's latest flagship is the Honor 50 which was opened for pre-orders in China in June. It is expected to be made available in European markets this month.

    The Honor 50 Pro and the Honor 50 are powered by Qualcomm chips while the cheaper Honor 50 SE is built atop a MediaTek SoC.

    In a tweet Honor said on 12 October: "Honor has succeeded in confirming co-operation with a number of supplier partners in the early stage.

    "#HONOR50 series will be equipped with Google Mobile Services, which will provide a more comprehensive application environment and extraordinary mobile experience to our customers,”

    In the absence of the proprietary version of Android, Huawei has been using an operating system known as HarmonyOS which is a port of the open-source version of Android.

    The Google proprietary apps — Gmail, YouTube, Drive and the Google Play Store among others — are essential for people who use smartphones in the west. They are not needed in China, a country in which Google ceased doing business in 2010.

    Three Republican senators, meanwhile, are pushing for Honor to also be banned as Huawei was. As iTWire reported last Friday, Marco Rubio and Rick Scott (both from Florida) and John Cormyn (Texas) said in a letter to US Commerce Secretary Gina Raimondo that by not adding Honor to the Entity List, "the Biden Administration is allowing a commercial arm of the Chinese Communist Party to evade American export controls and exploit our technological sector".

    There have been reports earlier this year that the Pentagon and Energy Department wanted to blacklist Honor, while the Commerce Department and the State Department were opposed.

  • iTWireTV Interview: Zebra Technologies talks its new ET80/ET85 (ET8x series) 12-inch 2-in-1 tablets and Field Vision Mobility Study

    GUEST INTERVIEW: The ET8x series of Zebra Technologies 2-in-1 tablets has arrived, with Wi-Fi 6E, 11th-gen Intel processors, superb rugged designs with detachable keyboard, and with the ET85 model, the addition of 5G via SIM or eSIM. Join Zebra Technologies A/NZ Sales Manager Brett Newstead, and Sales Engineering Manager Daniel Park on iTWireTV to explain all and showcase the impressive ET8x range.

    Zebra Technologies. The company started in 1969, an incredible 52 years ago, and today, empowers the front line in retail/ecommerce, manufacturing, transportation and logistics, healthcare, public sector, and other industries.

    The company is an innovator at the front line of business with a range of devices and technologies, with the latest ET8x series billed as “a new series of Windows 12-inch rugged tablets and 2-in-1s designed to improve productivity and safety across multiple industries.”

    Both models are the first to support Wi-Fi 6E, with the ET85 the first to support 5G, which, as the company claims, provide “advanced wireless connectivity to help ensure mobile workers remain connected in any environment.”

    They also offer 11th-gen Intel processors, in an era where some competitors still have models on the market with 10th-gen processors and can be augmented with a separately purchasable detached rugged keyboard featuring a friction hinge so front-line workers can experience a complete laptop-like experience on the go, in their vehicles or at their desks.

    iTWireTV spoke with Zebra Technologies A/NZ Sales Manager Brett Newstead, and Sales Engineering Manager Daniel Park https://www.linkedin.com/in/daniel-park-68503a4/ about the new models, as well as Zebra’s Field Vision Mobility Study which you can freely register for to read here.

  • Review: OPPO A94 5G is the big brother of budget 5G phones

    The OPPO A94 5G is the third low-budget model from this Chinese vendor released this year, and also the most expensive of the lot, the others being the A54 5G and A74 5G.

    It may come as something of a surprise, but in some aspects the two cheaper models — the A54 retails for $399 and the A74 for $449 — are better than their pricier cousin, which sells for $599.

    But then this is a marketing strategy to ensure that if someone is fixated on buying an OPPO 5G, then they will pick up one of the three, using their own reasoning to convince themselves that they have got the best of the bunch.

    No matter what they pick up, the cash registers at the same parent company — B.B.K. Electronics, which also owns vivo and OnePlus, and has an interest in realme — will ring when the purchase is made.

    {loadposition sam08}The A94 5G is, like all its compatriots, a black brick, weighing in at 173 grammes, and thus is quite light in the hand. It is slim, being 8mm thick and fits quite well into one's hand. You'll find the words "acceptable" and adquate a few times within this review and that's what the A94 is: adequate and acceptable for the price.

    Unlike some earlier models — I have been using the A91, a 4G model, since May 2020 — the volume buttons on the left are encased in a single sleeve, though they are separate on the phone itself. Personally, I would have preferred if they were separate in the sleeve as well.

    sky in box hill

    The A94 takes clear, detailed pictures in daylight conditions.

    The rear cameras make a noticeable bump, sitting well above the case that comes along with the device. Within that bump are 48MP f/1.7 main, 8MP f/2.2 ultra-wide, 2MP f/2.4 macro and 2MP f/2.4 depth-sensing cameras. In the front, there’s a 16MP f/2.4 camera. This setup is the same as its two cousins.

    The pictures are good, especially those taken in daylight. Those taken at night are acceptable, but in saying that one has said it all.

    One point of difference between the A94 5G and the other two models is that the A94 has only the bog standard refresh rate of 60Hz. The other two offer the option of 90Hz as well and this is one area in which some may pick them, rather than the A94.

    But when you look at storage and memory, the A94 scores, with 128GB of storage space and 8GB of LPDDR4X RAM.

    gaming image

    Gaming is a bit of a drag at 60Hz. Supplied

    The battery is adequate at 4310mAh and took 46 minutes to charge from 5% to 100%. As the phone can support 5G, perhaps the battery should have been a bit bigger; when one is connected to 5G, the battery does tend to run down pretty soon. The supplied charger supports 30W charging, which is kind of mid-range.

    The AMOLED display is bright and clean with a screen ratio of 90.8%. Scrolling is smooth, though, as with many Mitek processors, there is the occasional stutter.

    And one thing that was noticeable is that the connection, be it Wi-Fi, Bluetooth or mobile, occasionally tends to drop out. And one bug that still remains in the messaging setup is that the occasional text tends to come in rather late.

    The A94 runs ColorOS 11 laid over Android 11. It does not come with a whole load of crapware like some other brands.

    night climber

    Pictures taken at night are acceptable.

    The device is built on a MediaTek Dimensity 800U which promises to provide 5G that's always on. In practice, there is the occasional drop out. There is a single SIM slot and an SD-card slot as well.

    Given that this SoC can support refresh rates of up to 120Hz, it is somewhat surprising that the device is restricted to 60Hz.

    The sound is surprisingly good when one uses the supplied headphones.

    One downside of the device in Australia is that it is tied to the Telstra network. The 5G offered by Australia's biggest telco is erratic to say the least and also quite expensive, with the cheapest plan offering only 80GB a month for $65.

    But then if one has no objection to being tied to this provider, then the A94 can be bought here outright or on a plan that runs from one year to three.

    telstra 100

    Yes, this is 5G, courtesy Telstra.

    Personally, I would opt for a 4G plan and wait until there are really good reasons to go in for 5G. Australia has a more than adequate 4G network and the speeds are pretty good for the moment.

    The other two 5G networks that are being built, Vodafone and TPG, will, hopefully increase the competition and bring down prices. At the moment, all four providers - Optus is the fourth - appear to have plans that are around the same cost.
