4G Fries Freeview In Uk

Recommended Posts

Errr, slightly misleading topic there. The UK has commenced a test transmission period to identify any issues that may arise (and take remediating action such as install filters in viewer's antenna systems) but 4G has in no way 'fried Freeview'.

Will there be problems? Yes. If anyone is interested OFCOM performed some tests in 2011 to determine what sort of interference might be expected. Read about it here. Page 55 contains a non-technical summary of conclusions.

Out here 4G, from what I heard today in Parlement, will fry all those radio lapel mics used in theatres, schools and churches.

Chopsus,

The digital TV restack group has been testing LTE (4G) in Bendigo to see if high powered;

ABC 48 1.25 MW

BCV51 895 kW

VTV 54 895 kW

affects the operation of the LTE receivers in the cell towers as well as the receiver section in the phones.

The big concern to TV broadcasters is what guard band width will be used above the top edge of channel 51 to prevent interference from the transmitter section of the phone and the cell transmitter to TV reception. It would appear that there will be a guard band of 6 MHz which equals the width of TV channel 27 whcih is not included in the restack plan.

As for radio mics, they are currently sharing some UHF TV channels in the area to be vacated by TV. Some frequency shifts will be required to not share frequencies with the 4G phone frequencies.

I think I will believe what I hear in Parliamentary Question time thanks Alanh - the details you have posted above are redundant to the issue I was reporting

I wonder how real the 4G interference issues supposed for the use of Channel 51 here will end up being.
