Wireless@KTH are pleased to invite you to an exciting Friday seminar:
Date and time: Friday 7 September at 14:30.
Speaker: Torbjörn Johnson, Founder, President & CEO, Radio Innovation Sweden AB.
Topic: Radio Innovation's Super Effective Antenna Systems
Abstract: ”With pioneering development, it happens” – somebody with good insight and experience in the technology and the needs of end customers combines a great number of simple solutions that enable us to make a big leap to the introduction of lower cost, higher speed, wireless everywhere.
Antennas in the mobile base stations have since long been built with principles of the past. Antennas have not had any high priority, nor do they have a high cost for an operators total Capex. As long as they work, it has been “sufficient”. The forgotten components.
But what happens if someone, after 18 years of R&D, optimizes and changes the total technical praxis how the antennas are designed and suddenly demonstrates that the total efficiency can be improved 50 -100 times and the whole network economy, both Capex, Opex and Energy consumption can be reduced dramatically, from rural to urban sites!
This is exactly what Torbjörn Johnson at Radio Innovation Sweden AB has done. Torbjörn’s newly patented antenna system solutions to install the antennas modularly with up to 256 dipoles instead of as today 8, and increase the number of sectors per site from todays 3 to 6, 9,12, 18 or 24 makes the sites get booth a significantly improved coverage area (5-16 times) and Data Rates, but also increase the capacity up to 8 times compared with standard antennas, without increasing the wind loading on existing towers. The SAS Super Antenna System has been tested in the field in selected countries and areas and demonstrated that it meets the technical claims, predictions and operators expectations.
An important question that often is brought up is, if with existing radio equipment, the field strength or power flux density (which is important not to exceed human exposure limits) near the antennas is increased. The answer is ”No” and the contrary. The solutions result that the gain in the near zone 0 – 1 000 m is reduced, and increasing it from 2 000-20 000m. At the same time allocate the signal over a significantly larger area, which in turn means significantly lower field strength in the near zone according to ICNIRP och 3GPP MCL requirements. The customers that happen to live in the fringe 50-75% of site areas receive a better indoor signal, Data Rate and quality.
Even if the technical specifications on Coverage Area, Data Rates and site Capacity are impressive for the new Super Antenna Solutions, it is the economy when operators build out or upgrade existing towers with these antenna solutions together with RI’s 50 site planning rules, that the cost savings become revolutionary. The ROI calculations and LTE-A site costs/GB in different global networks show that the number of base stations for G2,3,4 and their Opex can be reduced by 70-86% in booth upgrade and new countryside sites, even for all customers nationwide. This without putting the countryside customers at lower Coverage quality and Data Rates or monthly Capacity.
A reduction of the total number of base stations required in a country for LTE is not only an economical issue for operators – it is also a savings of natural resources as spectrum and energy. To upgrade from GSM-voice, to LTE-A mobile data at > 350Mb/s and 150GB/customer/month to all 100% people in the country, several drastic technical and economical improvements are needed.
The ambition within EU is that as soon as possible enable higher speed mobile services (> 30 and up to 150 Mbit/s) to all within EU inclusive countryside people. Shall this be possible and at the same time reduce the costs, it is important to adopt new ideas and super-efficient solutions.
Radio Innovation now introduces the SAS (Super Antenna System) solutions and challenges traditional solutions and femtocells to improve the mobile networks Coverage, Quality, Data Rates, Capacity and Economy. Join the KTH-Wireless seminar on September 7 at 14.30, to listen to Torbjörn, and discuss with him, when he presents the new technology.
