ATDI delivers a Spectrum Engineering Software for Earth stations and Satellite networks to the Communications Regulatory Authority of Iran (CRA).

The mission of CRA is to achieve a competitive and balanced market for providing new and comprehensive services with reasonable costs in the field of ICT as the infrastructure for the State development in all aspects.

ATDI and its partner in Iran, Danafan Communications Development, have been choosen by CRA to deliver ICS manager and ICS telecom software products, as well as full training program and database migration. The contract was awarded in the framework of a public tender procedure.

The system delivered will help the International specialized organization bureau of CRA to perform the following tasks:

• Planning and management of radio spectrum
• Customers applications processing
• Management of frequency assignments
• International notification and coordination
• EMC analysis

The main responsibility of the International specialized organization bureau of CRA is international registration and frequency coordination of earth stations and satellite networks and solving the problem that caused by them.

This summer’s Olympic Games will be the pinnacle of achievement for many athletes but for ATDI it’s a case of been there done that.

The company supplies planning and modelling software, including ICS telecom and Spectrum-E, to Brazilian regulator Anatel; with the spectrum demands associated with the football World Cup in the country successfully negotiated during 2014, the expectation is for a similarly smooth ride when the Olympics arrive in August.

Demands on spectrum resources during global sporting events – the World Cup and Olympics are the world’s biggest – are huge, and coordination of all the temporary uses of spectrum creates a major headache for regulators. ATDI, though, has the cure.

Anatel were under incredible pressure to make everything work during the World Cup,” says ATDI project manager engineer Vanessa Deligi, “but, with the help of ICS telecom and Spectrum-E, everything worked; Anatel staff were able to do everything they wanted. I believe that, during the Olympics, the systems will perform better than ever.”

She adds that ATDI’s software has automated processes for Anatel, vastly speeding up interference analysis and frequency nomination. “Before they started using ICS telecom and Spectrum-E, many calculations were done manually. ATDI has been able to customise its software for Anatel own workflow so that requests for temporary spectrum usage now get an answer much faster.”

Vanessa notes that ATDI’s tools and associated consultancy services have allowed Anatel to better manage its workflow and greatly speed up its coordination with the companies seeking to use spectrum during the World Cup and Olympics.

“Anatel needed systems that were fast, efficient and robust during the World Cup and that’s what they got,” she states. “During the Olympics, that will happen again.”

To meet all the demands of 4G cell phone users at the World Cup, Anatel requested that all Brazilian cell phone operators provide 4G coverage in the 12 cities hosting World Cup matches. With the help of ATDI tools, Anatel staff were able to place all the cellular base stations in the map to check if each operator was meeting its obligation to provide the required 4G service. ATDI software was central in helping Anatel ensure the level of service that mobile phone users have come to expect.

ATDI announces new GSM-R Intermodulation features

The unwanted intermodulation phenomenon comes from the non-linearity of the amplifier in the receiving chain and is generated when two (or more) signals are present in a non-linear circuit.
For example, two signals of frequencies 2f1 – f2 and 2f2 – f1 may appear in the receiver: these are intermodulation products.
The receiver, listening to a channel whose frequency is f0, is interfered by intermodulation products when the following conditions are met:
. f0 = 2f1 – f2 or f0 = 2f2 – f1
. the strength of the signals f1 and f2 is above a given threshold
For wideband (UMTS, LTE) signals, it has been shown that a receiver generates IM products by mixing different spectral components corresponding to multiple GSM channels
of 200 kHz bandwidth that just one UMTS or LTE signal occupies (intra-signal intermodulation).
