worried that the antenna you are about to installation gained’t be hard enough to live to tell the tale to your environment? don’t be – at ericsson’s take a look at middle each aspect is bashed, hammered, shaken, buffeted via high winds and exposed to extremes of temperature and humidity, all to make sure that they are able to face up to whatever you throw at them.
each bodily tool made with the aid of ericsson is a piece of complicated technology, but all of them have one element in not unusual – they all need to paintings, regardless of what the conditions.
an antenna deployed in sweden will ought to resist snow, sleet, bitingly bloodless winters and lengthy intervals of rain and damp weather – that identical antenna deployed in senegal will need to address an annual common temperature of 35 tiers and low tropical humidity, and every unmarried thing has to paintings as intended, regardless of wherein it is positioned.
the technique of making sure that everything is going according to plan starts offevolved at the ericsson take a look at generation center in rosenheim, germany, in which materials and additives are constantly being positioned thru their paces before being added to distinct prototypes and merchandise, sooner or later finishing up in a tested design that is ready for production.
a first-rate thing of checking out for antennas is environmental sturdiness, and wind load is one of the most essential elements in antenna design. as the antennas are often very exposed at the top of masts, they want with the intention to stand robust, even if buffeted with the aid of extraordinarily strong winds.
this offers quite a few demanding situations – they ought to be strong, but no longer so heavy that they want specialised transport, or big metal systems to guide them.
each adjustment in shape or form have to be tested to look if it offers an development on previous designs, and wind load management is one of the areas that has seen a few important developments through the years.
ericsson’s antennas are subjected to sizeable checking out in wind tunnels, with every minor layout adjustment minutely scrutinized to look if it has the specified effect. the products are examined from all angles with air flows of varying temperature and humidity to peer how well they cope.
the result is a wind load information sheet that permits communications service providers to make knowledgeable choices based totally on surprisingly correct take a look at statistics.
teamwork key to checking out
being a part of the checking out crew might be one of the maximum enjoyable and rewarding jobs at ericsson – every day, the rather-professional participants get to give you new approaches of using modern era to explore for any weaknesses in substances or designs.
led by using christopher lynch, who is head of verification & take a look at structures, the group units a excessive benchmark for the entirety they do – positioned surely, there can be no compromising on best.
“that allows you to have the ability to check, build and deliver antennas and merchandise with the very best aspirations on satisfactory, performance and generation, we need to be able to test, verify and prove all the requirements of the goods,” he says.
antennas are designed to be each very sturdy, but sensitive, pieces of system and in spite of the checks taking region in a lab environment, christopher and his group do their fine to make sure that the results are as real as it receives.
assessments are achieved in real time and executed in line with the etsi (european telecommunications standards institute) 30 019 and iec60068-2 standards.
the tests are usually executed in 3 stages – incoming inspection, environmental & electrical tests, and a very last inspection.
in the incoming and very last phases, the antennas are examined for pim (passive intermodulation) and scattering parameters (s-par), and there’s a visual inspection earlier than and after the environmental and electric sequences to look if there have been any adjustments caused by the tests.
the checks themselves are comprehensive, measuring how the gadgets reply to mechanical elements, temperature, humidity, wind load, durability, water and dust ingress, daylight and uv rays, salt mist and noxious gases.
shaken, not stirred
the closing step of the system is often trying out the finished product for transportation to make sure that it arrives at its very last vacation spot in best operating order.
the products are packaged up and subjected to repetitive shaking to ensure that all the additives live in vicinity, even if they have to be transported over hard terrain in a truck or van to their final vacation spot.
such checking out frequently well-knownshows special approaches of packaging and securing materials for shipping, which makes a valuable contribution to reducing waste.
outcomes emerge as the roadmap
perform a little components and products fail the some of the assessments? genuinely – the whole point of among the checks is to maintain going as much as and beyond the factor of failure, which is often at a point a long way past what they’ll be exposed to out of doors the lab.
the take a look at outcomes offer valuable remarks to product designers and engineers, allowing them to make their destiny creations even extra long lasting and presenting them with a roadmap of how to do so.
key to getting there as quick as viable is the involvement of the ericsson take a look at generation center as early as feasible. there’s little point in growing some thing all of the way to a prototype if a key issue isn’t fit for motive, so concerning the take a look at team early within the procedure ensures that improvement groups get valuable early remarks to hold them at the proper song.
records drives confidence
the end result of the exams isn’t always just excessive-appearing long lasting products in order to maintain running at a high stage in the course of their lifestyles cycle – it’s also encapsulated in a giant quantity of information that csps can analyze and use whilst making funding selections.
the adherence to properly-appeared enterprise testing standards makes it easy to examine and contrast one of a kind answers and to look what represents quality value for money in phrases of both capital and operational expenditure.
on the subject of the price of the work performed by way of the ericsson take a look at era center in bavaria, don’t simply take our word for it – placed it to the check. request their consequences from your nearby ericsson consultant and see for yourself how great checking out is not a hindrance on the street to achievement – alternatively, it’s far a important a part of it.
