<p>Australians are about to get a major internet speed upgrade, but outdated home hardware could leave many households paying for speeds they’ll never see.</p>
<p>From September 14, government-owned NBN Co will ramp up its broadband plans, with 100Mbps tiers jumping to 500Mbps and new “mass market multi-gig” options promising up to 2000Mbps.</p>
<p>NBN chief executive Ellie Sweeney said the initiative, called ‘<em>Accelerate Great’</em>, could help unlock a $400bn economic boost by 2030.</p>
<p>But she warned that the long-in-the-tooth, if still functional, equipment many Australians continue to use was the biggest challenge to delivering on that promise.</p>
<p>“Across the board, we have customers who may not have changed out a modem for 10 years,” she noted.</p>
<p>A Wi-Fi 4 router bought in 2013, for example, maxes out at 100Mbps, far below the new wholesale speeds.</p>
<div id="attachment_272990" class="wp-caption aligncenter"><img fetchpriority="high" decoding="async" class="size-full wp-image-272990" src="https://www.channelnews.com.au/wp-content/uploads/2025/09/Screenshot-2025-09-02-at-9.41.40-am.png" alt="" width="2666" height="1774" aria-describedby="caption-attachment-272990" /></p>
<p id="caption-attachment-272990" class="wp-caption-text">If you’ve got a dodgy connection, the NBN probably isn’t to blame</p>
</div>
<p>Even top-end Wi-Fi 7 modems can struggle with signal loss across large or multi-storey homes, raising the prospect that 8K TVs may still pixelate despite higher-cost, premium NBN plans.</p>
<p>“The risk is people are going to be paying for these high speeds, but they’re not going to experience it because their hardware is out of date,” Andrew O’Connor, TPG’s general manager of fixed line, told <em>The Australian</em>.</p>
<p>Research conducted by TPG highlights the problem facing telcos selling high-speed internet.</p>
<p>More than 80 per cent of consumers think telcos are responsible for Wi-Fi strength, with just 13 per cent recognising they need the gear that can handle a high-speed connection.</p>
<p>That disconnect has driven complaints and confusion, which telcos are now seeking to respond to.</p>
<p>For instance, Vodafone is bundling Wi-Fi 7 modems and mesh units with new NBN and 5G plans.</p>

										<content:encoded><![CDATA[<p>We’ve had the AX5500 model from Samsung’s new range of Air Purifiers in the office since its launch, and have already noticed a difference in odours and dust in the air.</p>
<p>Retailing for $799, the AX5500 is Samsung’s third-most premium Air Purifier (the flagship AX9500, or ‘The Cube’, costs $1,299). As such, it is able to quickly purify air, even in larger spaces.</p>
<p>Like other models in the 2020 Air Purifier range, the AX5500 features a ‘Front Air Inflow’ design that effectively draws in air. Air is then purified through three filtration layers.</p>
<p>The preliminary filter is washable, and captures larger particles like pollen, general house dust, and pet dander.</p>
<p>Then, there is the two-in-one filter. This includes an activated carbon deodorisation filter, which is designed to capture harmful gases and unpleasant odours, like carbon monoxide, formaldehyde, cooking odours and household cleaners.</p>
<p>The second half of this filter is the True HEPA filter, which promises to capture up to 99.97% of 0.3 ㎛ ultra-fine dust like smoke, mould and exhaust fumes (it also inhibits the spread of captured bacteria). If Australia continues to experience horrific bushfire seasons, air purifiers that can filter out smoke will become increasingly crucial.</p>
<p>When used every day, Samsung says that the two-in-one filter will generally have a lifecycle of 6 months to a year. The filters for the AX5500 costs $149.</p>
<p>The device lets you know when filters need to be replaced on the light display.</p>
<figure id="attachment_159530" aria-describedby="caption-attachment-159530" style="width: 2990px" class="wp-caption alignnone"><img decoding="async" class="size-full wp-image-159530" src="https://www.channelnews.com.au/wp-content/uploads/2020/08/AX5500_Air-Purifier_Samsung-4.png" alt="" width="3000" height="2000" /><figcaption id="caption-attachment-159530" class="wp-caption-text">Samsung AX5500 Air Purifier</figcaption></figure>
<p>Once air has been purified, this clean air is distributed efficiently by the dual-power fan through the three-way air holes on the top, right and left of the device (this set-up allows the AX5500 to set flush against a wall). The fan speed can be manually set, but in Auto mode it will be automatically adjusted to the particle and odour levels around it to keep the room clean.</p>
<p>On top of feeling like we’re breathing fresher air, we’ve also been impressed by how quiet the Samsung Air Purifier is, even when it’s on Auto mode.</p>
<p>If you’re looking for something even quieter – such as when you’re sleeping, for example – the ‘Whisper Quiet Sleep Mode’ operates with a softer air flow and is incredibly quiet at just 20dBA. It also turns the display lights off, so there’s nothing to disrupt sleeping.</p>
<p>The bottom of the unit is fitted with wheels, so it can easily be wheeled from room to room as needed.</p>
<p>We couldn’t measure exactly how much cleaner our air was using the AX5500, but we were reassured by the four-colour indicator display system, which gives you an instant reading on the air quality in your space.</p>
<p>When lighting on the display is blue it means the air quality is good (i.e., the PM10 level is 30 and below), the PM2.5/PM1.0 level is 15 and below and the gas pollution level is only at 1). Green indicates moderate air quality, yellow signifies poor pollution levels, and red means air quality is very poor.</p>
<p>In the product launch media briefing, Samsung demonstrated how the colour indicator changed from blue to yellow when an aerosol was sprayed near it, and back to blue again as the air was purified.</p>
<figure id="attachment_159531" aria-describedby="caption-attachment-159531" style="width: 1959px" class="wp-caption alignnone"><img decoding="async" class="size-full wp-image-159531" src="https://www.channelnews.com.au/wp-content/uploads/2020/08/AX5500_Air-Purifier_-Samsung-3.jpg" alt="" width="1969" height="1363" /><figcaption id="caption-attachment-159531" class="wp-caption-text">Samsung AX5500 Air Purifier</figcaption></figure>
<p>Like other recent Samsung appliances, the AX5500 can be controlled remotely via the SmartThings app. To do this, you will need to connect the device to your Wi-Fi network.</p>
<p>Through SmartThings, users can check indoor and outdoor air quality, turn the device on or off, control the fan speed, set timers, adjust other settings, and source useful device information.</p>
<p>The AX5500 is available at Samsung.com, JB Hi-Fi and The Good Guys now.</p>
<h4>Rating: 9/10</h4>

										<content:encoded><![CDATA[<p>I’ve been reviewing the ADAPT 460T earphones whilst at work and in my downtime, and have been blown away with how comfortable they are to wear, and how effective the Active Noise Cancelling (ANC) is.</p>
<p>As you would expect from co-branded EPOS and Sennheiser product, the 460T headset offers premium quality audio. It supports AptX technology, ensuring you have excellent sound when listening wirelessly via Bluetooth 5.0.</p>
<p><strong>Microsoft Teams certification</strong></p>
<p>In particular, I noticed how clear calls sounded on the 460T. The ADAPT series of headphones from EPOS are actually Microsoft Teams certified, which not only means they had to meet rigorous standards, but it also means they’re ideal for taking Teams calls. The 460T features a handy Microsoft Teams for one-touch access – which served me well, as our workplace uses Teams for calls on days where we work from home.</p>
<p>The stunning sound clarity on calls is likely due to the patented EPOS Voice technology, which promises to deliver a clear and natural listening experience.</p>
<p>Equally, there are two beamforming MEMS microphones on the headset, allowing you to be heard clearly too.</p>
<p>Another nice feature was the subtle vibrations the neckband made to signal an incoming call. The 460T can be actively paired with two Bluetooth devices at the same time, so you’re aware of calls from either your smartphone or computer at any one time.</p>
<p>It has a range of 20 metres, meaning you don’t need to be glued to your devices either.</p>
<p>The headset can store up to 8 devices in the pairing list, which is convenient when you’ve got a whole host of different devices that you switch between. It also makes it easy for these earphones to be used for both work and play, which is particularly useful in the work-from-home COVID era.</p>
<p>[wpdevart_youtube]rkG1pHA2L9Y[/wpdevart_youtube]</p>
<p><strong>Design</strong></p>
<p>While I love my heavy duty, over-the-ear headphones, I must say that the very light ADAPT 460T headset did make for a welcome change, particularly when you’re using them all day.</p>
<p>Basically, the neckband sits over your shoulders, while the in-earphones sit snug in the ear. The whole headset weighs just 50g so you hardly notice, particularly as they provide a completely wire-free audio experience.</p>
<p>The 460T comes with four pairs of earbuds, and their soft material was very comfortable. When put in properly the earbuds and ANC together were effective at blocking out disruptive ambient sound.</p>
<p>It has an impressive battery that lasts up to 14 hours playback time with ANC on (or 13 hours of talking time with ANC on). With ANC off, you get an hour longer for both listening and talking times.</p>
<p>The headset takes two hours to charge from empty to full. While this may sound like a while, it wasn’t a problem for me, as I generally put it on charge at the end of every day.</p>
<p>I normally think enterprise-type audio headsets look funny, but the 460T is sleek and modern. It’s a great mix between wire-free and standard earphones, in that I didn’t have to worry about any cables getting twisted in my hands, but it was easy to find the earpieces if I chose to take them out of my ears for a bit.</p>
<p>It has a nice black and silver colour (at the moment this is the only colour the 460T headset is available in).</p>
<p>This case is a bit larger than it needs to be, but it is sturdy if you’re the throw-it-in-and-go type.</p>
<figure id="attachment_159912" aria-describedby="caption-attachment-159912" style="width: 4990px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="size-full wp-image-159912" src="https://www.channelnews.com.au/wp-content/uploads/2020/08/ADAPT-460_A2_3Dview-1.png" alt="" width="5000" height="5000" /><figcaption id="caption-attachment-159912" class="wp-caption-text">EPOS ADAPT 460T</figcaption></figure>
<p><strong>Conclusion</strong></p>
<p>All in all, EPOS and Sennheiser have delivered a premium audio product, and have managed to make an enterprise headset sleek and stylish. I was blown away by both the quality of sound that the earbuds delivered, as well as how well the ANC blocked out exterior sounds.</p>
<p>Although this is a pricey product, I do believe it’s a worthwhile investment if you need to make calls and attend virtual meetings while working remotely. It did significantly improve the meeting experience of Microsoft Teams calls.</p>

										<content:encoded><![CDATA[<p>Sharp Australia has released five new A3 monochrome multi-function devices (MFDs) – the MX-M3071, MX-M4071, MX-5071, MX-M6071 and MX-M2651 – which are all based on the company’s successful A3 Colour Advanced and Essential model series.</p>
<p>The award-winning MFDs feature Sharp’s latest easy-to-use touchscreen display, along with enhanced productivity features, such as the ability to feed up to 50 envelopes from the standard paper drawer.</p>
<p>The new lineup is also equipped with the new Adobe Embedded Print Engine technology, which is standard on the Advance Series, to enable users to print PDF files directly from a variety of sources with greater performance and accuracy.</p>
<p>The new lineup of MFDs integrate seamlessly with today’s complex network environments and support enhanced cloud services that now include Box and Dropbox.</p>
<p>Sharp’s new Application Portal lets administrators easily add new apps and update existing apps right from the MFP touchscreen.</p>
<p><img loading="lazy" decoding="async" class="aligncenter size-full wp-image-148068" src="https://www.channelnews.com.au/wp-content/uploads/2020/02/260bce1e-41f3-40d1-b290-0c9e798acabe.png" alt="" width="763" height="429" /></p>
<p>These next-gen models also deliver leading-edge security features, such as Firmware Attack Prevention and Self-Recovery, which can identify a malicious intrusion and restore the machine firmware to its original state.</p>
<p>The new Application Whitelisting feature protects the machine’s file system from unauthorised access. Additionally, administrators can centrally manage select settings using Active Directory Group Policy.</p>
<p>And, even if you operate separate networks with different security or usage restrictions in the same workplace, everyone can still share the same Sharp MFD as both Advanced and Essential model series support dual LANs, which can be connected to two different networks – one of which could be wireless.</p>
<p>So, whether you are producing meeting materials, printing reports, scanning documents or securely sharing key information, you can do it all with the new Sharp range of A3 MFDs.</p>

										<content:encoded><![CDATA[<p>Epson further reinforces its commitment to sustainable business solutions with the launch of seven new WorkForce devices aimed at small businesses and corporate customers who want to efficiently produce more while using less energy.</p>
<p>The new range of Epson WorkForce Pro and Enterprise business print devices will be available to Australian customers from April 2020, with purchase prices starting from $4,995.</p>
<p>All powered by Epson’s Precision Core heat-free print technology, the new range of heat-free A3 multi-function printers starts with the compact WorkForce Pro WF-878R desktop printer and culminates in the ultra-fast 100ppm WorkForce Enterprise WF-C21000 device.</p>
<p>According to Epson, its heat-free print tech uses no heat in the printing process and up to 87% less energy to print a page than a comparable laser-based device. This energy saving translates to reduced CO2 emissions and printer-related electricity costs.</p>
<p>“Business inkjet is expected to account for over 40% of developed business print solutions within the next five years,” said Craig Heckenberg, Epson Australia MD.</p>
<p>“As a result, Epson has taken steps now to help the market with its requirements in this area, placing particular emphasis on heat-free and energy efficient solutions.”</p>
<p>“These new products perfectly position us and our channel partners for future growth as they provide a sustainable, economical print solutions for organisations that are becoming increasingly aware of their carbon footprint, while at the same time seeking ways to reduce operating expenses.”</p>
<p>The WorkForce Pro WF-C878R, WF-C878RTC, WF-C879R and WF-C879RTC models deliver extraordinarily high ink yields, which produces up to 86,000 pages in black and up to 50,000 pages in colour.</p>
<p>Where time and deadlines are important or finishing options are required, the WorkForce Enterprise WF-C20600 (60ppm), WF-C20750 (75ppm) and WF-C21000 (100ppm) models come into their own, with a comprehensive range finishing options, including offset finishing and stapling, booklet-making and automatic hole-punch.</p>
