Regulation and practical measures in the CEERWG countries for the handling of interference between DVB-T and LTE in the 800 MHz band: this questionnaire has been launched on 22 April 2015 and last updated on 3 June 2015 - further updates are welcome to ceerwg.secretariat@ancom.org.ro

Regulation and practical measures in the CEERWG countries for the handling of interference between DVB-T and LTE in the 800 MHz band

-  Last updated on 3 June 2015 -

 

NRA/Question

Deployment of LTE networks in the 800 MHz band (e.g. implementation status, BS implemented in areas where DVB-T channel 60 is used, etc)?

Have interference cases been detected between LTE and DTT (approx. amount of cases)?

 

Type of interference detected (e.g. amplifier overload, out of band emission from BS, DTT tuner overload from LTE UE into portable set top antennas, etc) and possible solutions for eliminating interference (filters, reduction of BS power, etc)

 

Who is responsible for the elimination of the interference and for the relevant expenses?

 

What kind of regulatory measures have been taken to avoid or minimize interference?

- relevant regulation (e.g. obligation specified in the tender documentation, in the licenses, etc);

- measures to prevent interference (e.g. detailed calculations, analysis before implementation, restrictions for the mobile base stations power, etc.);

- obligations if interference is detected.

Is there any kind of support for the consumers (e.g. special website or hotline to report interference, guidance or technical support, etc)

HAKOM - Croatia

Two LTE800 networks (15 MHz channel bandwidth) are deployed. There are around 80 base stations installed mostly in rural areas or in visually prominent locations. Installation of a larger number of base stations in urban areas is expected in near future. DVB-T channel 60 is not used in Croatia.

No inteference case has been detected.

n/a

For time being a temporary procedure adopted by HAKOM is in force where HAKOM covers expenses of filter and its installation at the customer's side. This procedure sets out a complete process of eliminating interference cases by cooperation between the mobile operators, broadcasting operator (OiV - Transmitters and Communications Ltd.) and HAKOM.

After this temporary procedure mobile operators will be responsible for the elimination of the interference and for the relevant expenses.

Obligation specified in the licenses regarding DVB-T reception free from interference are:

- mobile operators are obligated to establish mutual cooperation and single point of contact for reporting DVB-T inteference cases,

- mobile operators have to identify the license holder whose base station is causing a interference,

- the license holder whose base station is causing a interference has to:

1. immediately stop base station operation until interference is eliminated,

2. carry out research and accordingly eliminate the interference

the license holder is obligated to maintain the log about reported interference cases and interference elimination

Existing DVB-T operator OiV - Transmitters and Communications Ltd. website and hotline are used to report interference for time being.

So far, two out of the three operators holding spectrum in the 800 MHz band have developed LTE networks in this band (10 MHz channel bandwidth). 425 LTE base stations are installed in the 800 MHz band, both in rural and in urban areas. 

DVB-T channel 60 is not used in Romania.

No interference case has been identified between LTE and DTT.

n/a

Mobile communications operators are responsible taking the necessary actions, on their own expense, to remove the harmful interferences that are caused by or may be imputable to them.

Relevant regulations and technical aconditions provided in the Terms of Reference and in the licences.
