Legacy mobile phones

Legacy Mobile Phones

The original ‘smartphone’ – Nokia Communicator

Remember way back in the late 90’s and early 2000s, when Nokia ruled the mobile phone market, they launched the Communicator series. Essentially it was the coming together of a mobile phone and a PDA, joined with a hinge that ‘opened up’ to reveal a full QWERTY keyboard and display screen. Always somewhat big and bulky, it initially was way ahead of anything else, offering phone, text, email and even fax communication.

The E90 was the last and most feature-packed variant, produced in 2008. More compact and powerful, it featured colour screens inside and out, video and photo cameras with flash, 3G telephony, Bluetooth and WiFi connectivity, together with internet browsing, GPS maps, photos, video and music players, radio, clock, calendar, contacts and a file manager, plus games and the ability to install apps like quick office for document creation and spreadsheeting. In short, it had everything we’ve come to expect in a ‘smartphone’, lacking one key ingredient – a ‘touch’ screen.

10 years on, it’s a testament to Nokia’s impressive build quality that it looks almost as good as new and still works as well as it did, though of course without the ability to pinch, zoom and swipe, and no ‘app store’. The photo and video quality now looks very basic, as do the limited number of games and apps; but it is possible to load it up with an up-to-date Opera web-browser and Google maps. The music player still works well, using a headset or in speaker mode, as does email and texts – and naturally it can still make telephone calls!

The Nokia phone business itself didn’t fair so well, being eclipsed by the competition and then sold off, as recently well documented in “The rise and Fall of Nokia” (shown previously on BBC4, now on youtube) by Arto Koskinen. However, more recently Nokia phones have made a bit of a comeback, relaunched by HMD Global. Though probably no hope of a new Communicator model?!

Mobile phones for all – Nokia 5110 ‘featurephone’

If you can remember the 20th Century and the dawn of the mobile phone, then the Nokia 5110 maybe familiar. Introduced in 1998, during the period of Nokia’s seemingly unstoppable rise, and helped them become the world’s number one mobile phone producer, which they remained for the next 14 years.

Nokia 5110

‘Featurephone’ for all – Nokia 5110

This was the breakthrough when phones ceased to be ‘bricks’ (though still including an external antenna) and became mass-market devices that everyone could consider carrying, even just as an ‘emergency’ phone. Text messaging was included, though many people at the time couldn’t see what the point of that was: “its easier to just ring someone, isn’t it?” How times have changed! Plus it had a clock, calculator, and a choice of ring tones including the now famous ‘Nokia tune’. And Nokia introduced the world to ‘snake’, heralding in the era of mobile gaming. No app store yet, and ‘touch screens’ and even colour displays were still to come. But you could now choose the colour of the product; they didn’t have to be just black anymore!

'snake' game

Nokia 5110 – ‘snake’ game

The phones themselves were of the solid long-lasting construction that characterised the products of that time from the Finnish manufacturer, perhaps due to the harsh winter environment of home they were built to survive, which is why 20 years later, it still works! Looking back, the surprising thing is that despite its rugged nature, a case was often used, and given the (now, seemingly) impressive talk and standby time, it was quite usual to have a spare battery too. Perhaps that was because they were still seen as an expensive luxury, and given that ‘normal’ desk phones didn’t run out of power, ‘early adopters’ wanted to make sure they could always make use of their investment.

Much has since changed in the world of mobiles, such that they’re not even used much as just ‘phones’, and Nokia’s phone business itself came and went, though now being revived by HMD Global. On the cusp of the launch of a new ‘flagship’ model, the Nokia 6.1 plus, it’s also interesting to see the ‘re-introduction’ of some ‘classic’ phones, the 8110 and 3310, harking back to those early beginnings.

Nokia, Marconi and Ericsson SDH – ‘Synfonet’, ‘SMA’ and ‘OMS’

SDH Network

‘Legacy’ Networks; long history, but still important and operational!

Back in the day, when PDH (Plesiochronous Digital Hierarchy) was all there was for telecommunications optical and copper transmission, a familiar site was the ‘Multiplexer Mountain’.

PDHMultiplexers

PDH Multiplexer Mountain

Then came the new transport technologies: SDH (Synchoronous Digital Hierarchy) for high-speed digital communication (via optical fibre and radio links); and (D)WDM ((Dense) Wave Division Multiplexing) as an optical solution for raising the capacity of existing fibre networks (particularly when the fibre-count was limited).

Nokia launched the ‘Synfonet’ range as the big brother to their successful ‘Dynanet’ PDH portfolio, with SDH capacity of initially STM-1 (155MBit/s) and STM-4. Later came STM-16 and WDM.

Synfonet – STM-1/4
  • All in one subrack (REG, TM, ADM, DXC)
  • Wide range of tributaries
  • 64kbit/s cross-connection server
  • Upgradable from STM-1 to STM-4 while in service

  • 4–channel multiplexing / demultiplexing
  • 8-channel multiplexing / demultiplexing
  • Up to 20 Gbit/s per fibre

But in 1999, Marconi Communications acquired (for over $100M) Nokia’s Synfonet brand, SDH and DWDM transport equipment products and about 120 staff from its Cambridge research and development business under the deal.

Inevitably over time Marconi rationalised their portfolio and the Synfonet range was discontinued, in favour of the SMA and MSH SDH equipment.

Business however took a downward path and in 2005 Ericsson acquired the key assets of Marconi (for SEK 16.8 billion). “Marconi” then became the registered trade-mark branding for Ericsson to promote these products, until phasing them out.

From 2007, Ericsson launched the (still) Marconi® branded OMS (Optical Multi Service) portfolio of advanced SDH multiplexers, including OMS 1200, OMS 1400 and OMS 1600 providing multi-service products for Metro-Edge and Metro networks. The “Marconi” brand was later dropped by Ericsson for this OMS range.

The OMS range provided packet evolution capabilities to Ericsson’s optical networking portfolio and strengthened its Full Service Broadband offering, meeting the demand from operators to evolve their network to support a mix of services and traffic types, with dexterous backhaul connectivity, TDM or Ethernet-based, with telecom quality, flexibility and scalability.

Perhaps this ‘potted history’ helps explain the ’journey’ these products took, and clarifies why they can be referred to as both Nokia and Marconi, or indeed Ericsson. Although now discontinued by these manufacturers, the products are extensively deployed and still in use by Telecoms Operators, Utilities and Transport companies.

Supporting ‘Legacy’ Networks and Keeping Customers Operational

From time-to-time Customers benefit from services from @YellowsBestLtd

  • Locating Nokia, Marconi, Ericsson (and other vendors) hard-to-find replacement items
  • Hardware repair services to existing parts
  • Supplying additional spares for newer systems to increase capacity or provide alternative interfaces

“TESTERS” – Test Equipment to suit all deployed technologies

Tester

Customers who own infrastructure systems usually require some form of test equipment to assist with the build, operation and maintenance activities.

Given the mixture of old and new technologies now deployed, consequently the range of available test equipment options has grown considerably. And like the infrastructure systems themselves, new functionality demands and obsolescence issues also affect the associated test equipment needs and availability.

@YellowsBestLtd assists Customers by sourcing the required test equipment, supplying either modern or legacy units. Often refurbished ex-hire equipment in excellent condition and at commercially attractive prices makes sense over leasing. This ensures the continued availability of sets of the appropriate specification, which may become discontinued by the manufacturers over time.

If necessary, we can also arrange the repair of existing units, especially those that perform very specific functions that cannot easily be replicated with more recent equipment.

There follows a brief description of many of the types of test equipment available; we would be very keen to hear from you to understand your specific requirements, so please get in touch!

Data Centre Solutions – Keeping IT cool!

Keeping IT cool!

In order to get the best out of data centre infrastructure, ensuring equipment runs at its most efficient, reducing risk of failure and extending its life span, attention should be paid to ensuring the optimum operating environment. Efficiencies impacting on both the building cooling systems and power for room hardware (servers, switches, routers, etc.) means that improvements will pay for themselves, whilst also lowering the carbon footprint to the benefit of all. Solutions range from quick deployment for office computer room spaces with low power demands through to high density Data Centre applications delivering true containment giving scalability, mixed power zones and zero hot spots.

@YellowsBestLtd we would be very keen to discuss further; since the exact project requirements dictate the costs and savings to be gained, we can arrange a site survey as appropriate without cost or commitment. Hence please contact us; we look forward to hearing from you.

 

Ultrasonic Humidifiers

Low energy ultrasonic humidifiers have been widely used in data centre projects for many years. They consume a fraction of the energy of an equivalent steam humidifier, providing an assistance to data centre cooling with hygienic operation and virtually maintenance-free operation. There are a range of units available for installation within air handling units, cooling corridors or in the data hall itself, on any scale.

 

Cold Aisle Containment

Cold Aisle Containment is a non-intrusive bespoke retrofit to data centres, whereby the cold aisle is contained and supply and exhaust air separated to maximise cooling efficiency. By creating a positive pressure, air is directed straight into the servers, making them run more efficiently, whilst preventing recirculation of air back to the computer room significantly improves the efficiency of the building’s cooling system. Better control of the room’s temperature results in energy savings, and providing temperature equilibrium across all servers addresses the problem of overheating in the top third of the rack, where traditionally most server failures occur.

Legacy and New Infrastructure Spares

spares

Most Customers’ infrastructure systems now consist of a wide range of technologies from the very old to relatively recent, having been built to serve operational requirements for a number of years. In many cases, these requirements don’t significantly change, and it therefore makes sense to keep these systems in place to maximise the use of the investment and avoid whole-scale change-outs that would be costly, disruptive and unnecessary.

@YellowsBestLtd locates hard-to-find replacement spare parts to keep legacy infrastructure in operational service that has been deemed ‘obsolete’ by the manufacturers, as well as supplying additional spares for newer systems that can be used to increase capacity or provide alternative interfaces.

Typically we provide refurbished spares, tested and working, but often it is the case that unused products from surplus stocks can be supplied. Hence for both old and new systems, we are usually able to source parts at very commercially competitive rates and with short lead-times.

Here is a selection of items that we’ve recently been helping customers procure or obtain parts for. Keen to hear what requirements you may have, so please get in touch.

Reverse Logistics and Value Recovery

ValueRecoverySpares

With the New Year upon us, it’s a good time to take stock and prepare for this year’s activites and operational maintenance requirements. Its at times like these that decisions are made to move forward with projects to implement replacement systems, and/or ‘clear out’ unwanted infrastructure parts. One resolution we can all embrace is to ensure that a responsible Reverse Logistics process is followed.

Furthermore, it’s not always the case than there has to be a significant cost to disposal; unwanted infrastructure items in many cases can result in a generation of funds to Customers, either through resale of working spare parts or by recycling of components. This ‘Value Recovery’ can help to pay for replacement systems, as well as disposing of unwanted parts with the least environmental impact.

YellowsBest helps Customers perform their Reverse Logistics whilst achieving ‘Value Recovery’ by taking delivery of systems and parts, cataloguing the items, then providing a managed approach to the resale of spares, maximising the revenue arising. During this no-cost process, whilst the assets have been removed from the Customers’ premises saving storage space, they remain the Customers’ property and can be called back should unexpected spares requirements occur. Anything not saleable is then broken down for recycling, with useful materials extracted which can generate additional funds, and unwanted items disposed of in accordance with WEEE regulations.

We look forward to hearing from you; please get in touch to see how YellowsBest can assist with Reverse Logistics and maximise ‘Value Recovery’ for your organisation.

Reduce Reuse Recycle

ReduceReuseRecycle

@YellowsBestLtd helps Customers with their operational needs, and one aspect is to #Reduce the demand for avoidable whole-scale replacements through a combination of supply for #Reuse of refurbished spares and repair of system elements. When removal and disposal of no-longer serviceable infrastructure parts is necessary, we can also assist with the resale and #Recycle for ‘value recovery’ of valuable materials.

Most customers have implemented their private network infrastructure systems over a number of years, and for many their operational requirements have not changed. Consequently, it makes more sense both financially and environmentally to maintain these systems rather than embark on complete change-outs. We can assist by supplying critical and hard-to-find spare parts and hardware repair services, even when the systems have been declared ‘obsolete’ (i.e. no longer in production) by the O.E.M.

Eventually there does come a time when it proves necessary to remove and replace network infrastructure. Rather that simply discarding the old system elements, we can provide ‘value recovery’ to the Customer by means of resale of working parts and recycling of components, extracting useful materials. This often proves financially beneficial, generating a source of funds which helps to pay for the replacement systems, as well as providing an ethical means of disposing of unwanted parts with the least environmental impact.

Please get in touch should you wish to discuss your operational requirements and see how @YellowsBestLtd can be of assistance.

IET Achievement Awards 2017

iamwill

Delighted to have attended @TheIET @IETawards #IETAchieve ceremony on Wednesday 15th Novemeber 2017. Well organised with a good turnout at the impressive @theBreweryVenue, it was a chance to network with a very diverse, international mix of engineering professionals, academics, students, armed forces representatives and volunteers.

This year’s event was hosted by the very capable @AngelaLamont (best known for the #BBC1 It’ll Never Work? programme) who ensured the smooth running of the event whilst always keeping the tone enjoyable and interesting.

Naturally there were many awards. Key highlights included the Faraday Medal presented to Dr Bjarne Stroustrup for his revolutionary and now far-reaching work on the creation of the C++ programming language, and an Honorary Fellowship awarded to @iamwill‏ for his contribution to the engineering profession – helping to raise the industry profile even further!

The ceremony was interspersed with impressive and thought-provoking presentations by the Present Around The world (#PATW) global finalists, the audience being able to vote on presentation skills and technical content of the speakers, and so special mention goes to Shubham Saraff of the South Asia Region who emerged the winner with his presentation on “Neurons that Shaped Us”.

Next years’ @IETawards Ceremony, celebrating and networking as the winners of the #IETAchieve prestigious Achievements Awards and Scholarships are announced, will be held on 14th November 2018 in London.

Keen to hear more from others who attended this year’s event, or anyone interested in attending next year, feel free to get in touch!
