  • A strategic approach to radio technology :: RadioComms
    The most common way to check this out is to talk with other organisations that already use this vendor s equipment and services as well as ensuring high availability through the RFP process with clear requirements specifications and in contracts Another way to manage the risk of unreliable vendors or their networks is to insist on open standards to make sure non performing entities or components can be replaced quickly Security With increasingly sophisticated and aggressive cyberattacks security has become a must have Not only is access security important but high level encryption has also become essential Radio networks have very high security requirements due to high government use and are usually private ensuring others cannot access transmissions as easily as they can on the public cellular network The level of encryption within P25 networks is specifically designed for the higher requirements of law enforcement As an example the São Paulo Police Force s effectiveness had been previously limited by drug cartels intercepting their communications and disappearing before police arrived The Tait P25 network commissioned in 2006 has yet to be cracked by the crime syndicates and São Paulo Police attributed the contribution of the secure communications to a reduction in crime of 60 between 2006 and 2011 In São Paulo Brazil police say the establishment of a P25 secure communications system has led to a 60 reduction in crime between 2006 and 2011 Credit Julio Boaro Scalability While public safety entities may not be physically expanding regional mutual support agreements are becoming increasingly common New networks tend to expand and replace the older networks so that all parties can communicate by consolidating on one standard Utility CIOs understand that their companies may expand by procuring other utility companies Either way a smart CIO is going to make sure that the communications network can be scaled up to cover any eventuality Converging on the TCP IP communications protocol an organisation s networks can be managed from one console irrespective of the content of the TCP IP packet voice data etc Such convergence has already occurred in locations from a 60 000 resident city to the Los Angeles basin with 14 million residents The communications can involve any device including desktop PCs servers smartphones radios traffic signals etc Many regions have mutual support agreements among police and fire partly as a result of budget cutbacks but also to be able to project a larger response in the event of a local disaster Integrated communications platforms are essential to support coordinated multiorganisational responses Management To perform consistently any network requires ongoing support User administration security device monitoring and network monitoring are all key to maintaining network integrity and performance CIOs will want an extensive network management tool to be able to perform management functions effectively over the long term The same network management tools used for managing IT networks can be used to manage the TCP IP based radio networks A network addressable radio can be remotely checked for operational status its

  • Yagi - the man behind the antenna :: RadioComms
    a directional antenna they had developed at the university and it used several parasitic elements of directors and reflectors The Yagi Uda antenna was born The device was patented both in Japan and the US In America the antenna revived interest in magnetrons and in 1928 GE developed a 400 MHz unit that was tested using a wave projector Two years later a Yagi Uda antenna was used in an experimental aircraft landing system Diagram of a single director Yagi antenna By 1933 Yagi had moved to Osaka Imperial University as the first chair of the physics department where radar was being developed He encouraged his students and colleagues to study pure science and fundamental physics while he looked after applied physics for industry In the same year a government radio telephone link was established over the 40 kilometre distance between Tobishima and Sakata At the outbreak of World War II Yagi was made Dean of the Faculty of Science at Osaka University and remained a civilian consultant to the military on radar and communications until 1945 In that year he became president of the Technology Institute of the Cabinet With the war over Yagi became a consultant on the technical rehabilitation of Japan and helped to establish television standards Further honours came his way when he was installed as fourth president of Osaka University he also was president of the Japan Amateur Radio League and was president of the Yagi Antenna Co A simple antenna design The simplicity of the antenna has always been one of its greatest attractions and it is particularly effective at VHF and UHF frequencies where its physical size can be quite small Although its characteristics are narrowband it is a high gain device often 10 dB or more It is also highly directional comprising in its simplest form one driven element of a dipole or folded dipole plus a parasitic director in front and a reflector behind The reflector is normally about 5 longer than the dipole while the director is shorter than the driven element From this simple configuration multiple directors and reflectors can be added to create a highly personalised directional narrowband antenna Hidetsugu Yagi holding an example of the antenna that bears his name Credit Hitachi Kokusai Electric Inc Yagi Antenna Division The relationship between physical size such as element length the diameter of the elements and the spacing of the reflector s and director s can significantly alter the antenna s impedance and gain such that finetuning is often necessary for maximum performance Yagi antenna systems first came into widespread use during World War II but ironically not in Japan The development of radar particularly airborne versions had stimulated their adoption in Europe and the USA However in Japan rivalry between the army and navy prevented an awareness of the antenna until very late in the war even though the army knew of the device after the fall of Singapore in 1942 It s fair to say that the Yagi

    indicated using multiple symbols with two characteristics a vector magnitude representing the signal s amplitude and a vector angle representing the signal s phase An arrangement of multiple positions allows data communication Higher modulation schemes transmit a series of symbols each with different amplitude and phase allowing the communication of multiple bits at the same time such as 64 quadrature amplitude modulation QAM that can transmit 64 symbols at different positions each transmitting 6 bits The JD745A simultaneously shows every modulation format for LTE by individual downlink channel This means an engineer can immediately gauge the importance of an error vector magnitude EVM measurement relative to the format The unit also clearly specifies which control or data channel is being analysed EVM measurements can provide a great deal of insight into LTE modulation performance EVM is expressed as the difference between the vector of an ideal symbol and the symbol under test It is the percentage of error that indicates how far the symbol is transmitted from its ideal position The higher the modulation the higher the number of symbols which results in a smaller margin of error With proper use EVM and related measurements can pinpoint exactly the types of degradations present in a signal and can even help identify their sources The JD745A performs EVM testing on LTE data and control channels such as reference signals In the case of the Lucas Oil Stadium the unit revealed modulation degradation at the antenna point of the DAS indicating performance issues on that particular branch In addition the JD745A can measure from each antenna on a MIMO configuration identifying installation errors on cabling The timely detection of these kinds of problems can prevent significant troubleshooting complications such as misidentification or mislabelling of network elements Related Articles Anritsu PIM Master MW82119A
