РусскийThe transformation of residential telecommunications
Communication technologies evolve fast in an increasingly connected society. Social networks demand such a level of instant accessibility and they handle a volume of information which would have been unthinkable some years ago. Operators faced with these requirements become the main actor in supplying their customers, from the most conformist to the most demanding ones, with adequate bandwidth for their needs.

More bandwidth, new technologies
Bandwidth requirements at residential level exceed the most demanding business requirements of the past. Operators must take full advantage of the latest available technologies in order to quench the data thirst.
The rise in video exchange through social networks as well as the use of Apps for remote management of just anything manageable, they make any technology obsolete well before going through amortization.
Thus telecom networks based on FTTH fibre systems have been developed to provide all kind of services to the homes, and competing with it, DOCSIS 3.1 networks emerge to achieve similar Internet speeds, supporting Voice and TV services. Via cable, fibre or over the air the demand for bandwidth is always greater.

So what about the classical aerial television?
Terrestrial TV doesn't stay behind this fast-paced evolution. Since the analogue switch off terrestrial TV has been sacrificing its natural habitat by constantly releasing spectrum to wireless services.
- First the VHF channels vanished.
- Then, with the first digital dividend, the upper UHF channels were removed or ‘repacked’ to make more room for the wireless operators.
- And now the second digital dividend releases additional bandwidth squashing the off-air TV services further into the lower UHF.
First and second digital dividend in Spain.
At the same time however we demand higher quality TV. We wanted high definition as a start which required a higher bit rate and now, as TV screens grow bigger, 4k Ultra High Definition.
Demanding better quality while limiting bandwidth available. The terrestrial TV conundrum. How is it possible?
Reducing the spectrum occupancy while improving the quality of the TV services can only be achieved by using the latest compression and modulation technologies.
Compression technology has evolved from MPEG2 to MPEG4 and now H265 (or HEVC). In the same way DVB-T is giving the way to DVB-T2 on the part of modulation. We must make the most of these technologies knowing off-air TV will have little spectrum available and the new so called non-linear TV services spread without respite.

User experience is what matters regardless of the technology
And in this dynamic environment, in which every single player fights for a place in the home, the dwelling, the living room, every room, become the user’s shrine. The user is on command for he can choose and control what he wants to do and using what platform, with his remote control, laptop, tablet or his mobile phone.
With only “the content” in mind, user’s gain access to their services of choice using all sorts of devices almost unwittingly, not being aware of what technology lays behind.
To make this work we must create a very complex and reliable information network which most take for granted thinking that everything works as if by magic. No, it’s not a hat trick.
When things go wrong...
Every new technology requires going through a learning curve, maturation, but on a different plane it also requires installation and maintenance. And the technology may eventually fail or prove vulnerable to external factors.
Training, proper documentation and especially adequate Test & Measurement instrumentation are the pillars on which trade professional’s response is based. They will need them to help them face the challenges of nowadays home environment.
Both hardware and software require configuration, adjustment and updating. This is where telecommunication professionals come into play. Knowledge can make a difference here.
The importance of T&M
PROMAX is constantly helping professionals helping users to enjoy all these new technologies. The new equipment by PROMAX covers the measurement needs of TV antennas systems, CATV and FTTH networks and even WiFi.
Today’s homes are connected to the world using multiple technologies.
Modern homes are immersed in multiple technologies. RANGER Neo analyzers have an answer for each of these technologies. Whatever the signal type, DTT, Satellite, CATV, FTTH, OTT, IPTV, CCTV or WIFI, RANGER Neo multifunction analyzers are the best possible option.
PROMAX is a leading manufacturer of test and measurement systems, broadcast and TV signal distribution equipment. Our product lines include measuring instruments for cable TV, satellite TV, broadcast, wireless and fibre optics networks, FTTH and GPON analyzers. DVB-T modulators, IP streamers or IP converters (ASI, DVB-T) are among the company’s latest developments.
