Serious Hardware

Digital dream for the haves

Published

on

The new DStv Explora decoder is about to deliver on the unmet promise of previous versions, but leaves the have-nots even further behind, writes ARTHUR GOLDSTUCK.

The dithering of successive administrations at the Department of Communications has deferred the digital dreams of South Africa’s TV viewing public. The migration to digital terrestrial TV (DTTV), originally set for 2011, still has no due date. The Department has yet to issue tenders for set-top boxes needed by 5-million households to convert digital signals into an analogue feed for their old TV sets.

It was something of an irony, then, that a major announcement was made last week of a new set-top box. Sadly for the 5-million, the box had nothing to do with DTTV. For them, the dream remains deferred.

On the other hand, the new set-top box is good news for 4,4-million households that already have digital TV in the form of Multichoice’s DStv. In the past year, the number of subscribers grew by an astonishing 1,128-million subscribers.

When the DTTV migration strategy was first announced exactly five years ago, the DoC estimated that 7-million households would need set-top boxes. However, successive Ministers of Communication placed more emphasis on who would get the rights to manufacture the boxes than on digital migration itself.

Now we can see the exact cost of the delays created by this debate: the pie waiting to be shared out in terms of manufacturing requirement has shrunk by a third. And Multichoice has happily begun filling the digital donga left behind.

Not that the DStv set-top boxes have been a cure-all. Great things were expected when a high-definition version of its PVR decoder was launched in 2008, but it turned out to be a deep disappointment. It had lesser menu functionality than a standard decoder, and was a nightmare to synchronise with the standard version.

Finally, on 31 July, the future of set-top boxes arrived in South Africa. Multichoice unveiled the DStv Explora, a device sleeker than its predecessor, but with four times the recording capacity. It houses a 2 Terabyte hard drive, four times the size of the older model. This, says Multichoice, is enough to store 220 hours of HD content.

DStv BoxOffice has also been expanded, with 20 recently released movies, while DStv Catch Up now offers 30 movies on demand.

‚”We’ve expanded the number of series available and now also started to introduce series stacking, i.e. making two episodes of selected series available on demand,‚” says John Kotsaftis, CEO of DStv Online.

The most visible symbol of these changes lurks in the Explora’s more user-friendly remote control: it sports dedicated shortcut buttons to DStv Central, BoxOffice, Catch Up, Playlist, Search and Live TV.

Most dramatically of all, according to Multichoice South Africa CEO Collins Khumalo, is that the decoder will soon also allow for delivering content via broadband and remote recordings via the Internet.

The DStv Explora will arrive in stores from 15 August, selling at R2 499. While the have-nots are kept waiting, the haves are about to have a whole lot more.

Prepare for Wi-Fi 6

From traffic to healthcare, the applications of the new Wi-Fi 6 standard are set to transform how we connect.

Published

on

20 years ago, with the release of 802.11b, Wi-Fi began its conquest of the world networking scene in earnest. Wi-Fi can easily be called out as one of the most popular technologies of the last two decades. Just as mobile telephony and mobile internet, it has become a part of everyday life. And with the advent of IoT and the introduction of 5G, the time has come for the new standard – Wi-Fi 6.

Beyond being significantly faster than the previous generation, Wi-Fi 6 delivers up to four times greater capacity. Latency is vastly improved, allowing for near real-time use cases. Wi-Fi 6 is also easier on connected devices’ batteries.

So what impact will Wi-Fi 6 have on business in the coming years?

Digitisation, mobility and IoT are driving the need for connectivity. By 2022, more IP traffic will cross global networks than in all prior ‘internet years’ combined up to the end of 2016. In other words, more traffic will be created in 2022 than in the 32 years since the internet started. In 3 years, 28 billion devices will be connected to the Internet, many of which (robots, production lines, medical devices) will communicate over a wireless network. Against this background, it is easy to understand why we need a redesigned wireless standard that is more responsive to present and future challenges.

Wi-Fi 6: The business impact

“In the first phase, we expect the new wireless standard to gain a significant foothold in the B2B field, where it brings important innovations,” said Garsen Naidu, Country Manager, Cisco South Africa. “We will see it, together with other technologies, penetrate significantly into manufacturing, into the logistics industry. The technology is also more effective in high-density settings like large lecture halls, stadiums and conference rooms, so we are likely to see significant penetration in these settings too. And, with its extremely low latency, Wi-Fi 6 also promises to open up new opportunities in AR/VR, healthcare, and self-driving vehicles. ”

Ever since the launch of the Internet, every leap in network speed has had a major impact on technological innovation: 4G has brought along the age of smartphones, whilst 5G and Wi-Fi 6 will transform the business world. According to Cisco experts, these two technologies – 5G and Wi-Fi – will be widely adopted at the same time, complementing each other.

A short history of Wi-Fi

In 1999, half a dozen technology companies, including Aironet, which was later acquired by Cisco, formed the Wireless Ethernet Compatibility Alliance. The standard announced that year, 802.11b, which gained significant commercial traction, was the first to emerge under the ‘Wi-Fi’ brand. As such, 1999 marks the year in which Wi-Fi really began.

Solutions that carry the official Wi-Fi logo work consistently with the IEEE 802.11 data transfer standard. These solutions are certified by the Wi-Fi Alliance, which guarantees compatibility between various wireless devices. In addition, networking manufacturers have done a lot to improve compatibility. Launched as early as 2002, Cisco Compatible eXtensions is a free licensing program that has enabled other vendors’ Wi-Fi products to be securely deployed on Cisco wireless networks.

Subsequent developments in Wi-Fi technology included managing interference and increasing data stability. Cisco is supporting these with the Cisco Flexible Radio Assignment and Cisco CleanAir technologies. The latter is capable of identifying and graphically displaying radio interference, identifying the source of the problem, and directing users to other, less crowded, channels.

Challenges of the present and opportunities for the future

One of the most widespread business applications of wireless technology is office Wi-Fi. Using Wi-Fi, employees can move freely and access the network from anywhere where there is a hotspot. Wi-Fi-based analysis and location services are also becoming increasingly popular. And with the spread of IoT, Wi-Fi is becoming ubiquitous, and is today found everywhere from agricultural fields to production lines.

“We see promising business opportunities and a wide range of new applications. At the same time, with hundreds and thousands of new devices connecting to wireless networks, IT teams are facing increasing complexity. So we need to rethink IT architectures from the ground-up,” added Naidu.

Much of this need to rethink network architectures is driven by the enormous growth in wireless connectivity.

Wi-Fi has driven growth in general IT use, which in turn has led to the need to provide and run bigger and more complex networks with a greater variety of endpoint device types on them. This complexity ‘feedback loop’, driven in no small part by Wi-Fi, requires that new solutions are developed to deal with this complexity.

Cisco has pioneered in this area, using AI, machine learning, and machine reasoning, via products such as Cisco DNA Assurance to eliminate manual troubleshooting and reduce the time spent resolving service issues.

The latest Wi-Fi 6 developments introduced earlier this year make a consistent, efficient and seamless wireless connectivity experience a reality.

Now for hardware-as-a-service

Published

on

Integrated ICT and Infrastructure provider Vox has entered into an exclusive partnership with Go Rentals to introduce a Hardware-as-a-Service (HaaS) offering, which is aimed at providing local small and medium businesses (SMEs) with quick, affordable, and scalable access to a wide variety of IT infrastructure – as well as the management thereof.

“Despite an increasingly competitive business environment where every rand counts, many business owners are still buying technology-based equipment outright rather than renting it,” says Barry Kemp, Head of Managed IT at Vox. “The problem with this is that the modern device arena has grown in variety and complexity, making it more difficult to manage, and to reduce the overheads of controlling these devices.”

According to Kemp, there is a global trend being observed in businesses moving away from owning and managing IT infrastructure. This started with the move away from servers and toward cloud-based subscription services, and now organisations are looking to do the same with the remaining on-premise hardware – employees’ desktop systems.

The availability of HaaS changes the way in which local businesses consume IT, by allowing them to direct valuable capital expenditure toward the more efficient and competitive operation of their organisation, rather than spending on hardware products. 

“The rental costs are up to 50% lower than if they buy these products through traditional asset financing methods. Furthermore, using HaaS gives businesses the ability to scale up and down depending on their infrastructure requirements. Customers on a 12 month contract can return up to 10% of the devices rented, while those customers on 24 and 36 month contracts can return up to 20% of the devices – at any time during the contract,” adds Kemp.

More than just a rental

HaaS gives business access to repurposed Tier 1 hardware from vendors such as Dell, HP and Lenovo, equipped with the required specifications (processor, memory, and storage), and come installed with the latest Microsoft Windows operating system, unless an older version is specifically requested by the customer.

Kemp says: “Where HaaS is different from simply renting IT hardware is that businesses get full asset lifecycle management, such as having all company software pre-installed, flexible refresh cycles and upgrades, support and warranty management and transparent and predictable per user monthly fees.”

The ability to upgrade during the contract period means that businesses can keep pace with the latest in technology without needing to invest on depreciating equipment, while ensuring maximum productivity and efficiency for employees. Returned devices are put through a decommissioning process that ensures anonymity, certified data protection, and environmental compliance. 

Businesses further stand to benefit from Vox Care, which incorporates asset management and logistical services for customers. This includes initial delivery and setup in major centres, asset tagging of all rented items, creation, and the repair and/or replacement of faulty machines within three business days – again in the main metropolitan areas. 

Vox Care also assists in the design, testing and deployment of custom images, whereby HaaS clients can have the additional programmes they need (security, productivity tools, business software, etc) easily pre-installed along with the Windows operating system, on all their machines.

Kemp says HaaS customers can get further peace of mind by outsourcing the day to day management of their desktop environment to Vox Managed Services, as well as leverage the company’s knowledge and expertise to manage and host workstation backups to ensure business continuity.

Says Kemp: “Hardware-as-a-Service allows businesses to reduce the total cost of ownership of their hardware and ensure they only pay for what they use. Making the switch to a service model helps them take advantage of the global move in this direction, and to turn their business into a highly functional, flexible, low cost, change your mind whenever you want workplace.”
