032 INTERVIEW
stated Arvidsson. “It is user-selectable on the transmitter and all the receivers will auto negotiate with the transmitter side. The 5.8 band has more problems coming through the walls, and the higher the frequency the shorter the distance it can travel. However, generally for indoor jobs, such as exhibitions, where there is a lot of radio traffi c and the distances are not so great then you go to 5.8GHz - in that way you avoid wireless steadycam cameras on 2.1GHz and, mobile phone jammers - both of which work in a similar way. They are causing so much noise interference on the 2.4GHz band, because the output power is so extreme.” In fact the G4 platform has made a quantum leap. Aside from offering bi-directional data transfer it also embraced Adaptive Frequency Hopping, explained earlier. “This enables us to build up a history to see if a channel is interfered over a long time, so we will only remove ‘bad’ channels selectively.” Meanwhile, other network protocols are striving to establish themselves in other parallel sectors. For example commercial lighting uses the DALI protocol, designed as a successor to the analogue 0-10V, and is principally a standard for fl uorescent lamp ballasts. It has hardly taken the market by storm but then W-DMX has not become universal yet either. Will the lighting industry ever lose its security blanket of wired connection so that it catches on in the way that radio mics did? Arvidsson believes that it will. “At the end of the ‘80s, there were very few radio
mics, but my target is to get wireless lighting control accepted in the same way as the wireless mic. Obviously the audio business is much bigger, and lighting has more parameters; but wireless control is not only for situations where cable is not possible, but to save time, money, and be more fl exible and creative.” After seven hours in the company of this engaging entrepreneur it struck me that his ambitions could possibly best be summarised as “dynamically modest”, for principally he is an evangelist for the technology. “My target is to be able to grow at a decent rate, but I am aware that the bigger you get the more problems you will have. Presently we are a comfortable size. “We are spending 20% of our turnover on R&D and marketing events because the most important thing is striking a balance - fi nding a middle path between product and market development. It’s not always about having the Ferrari. As for Interlite, we did have an offi ce in Stockholm and we will reopen again next year as it’s important to be in Stockholm.” Replying to an unasked question, he stated: “If I were ever going to sell Wireless Solution I would only do it to someone who would care about it, [rather] than just to sell for money. There are too many venture capitalists and I see no place for them in the entertainment industry, which is only a niche market.” Meanwhile he is perfectly happy to continue his empirical journey into further uncharted waters.
