Will the main Winter Hill FREEVIEW transmissiions in NW England be affected by the 4G network switch on and if so will it simply be cheaper to ditch FREEVIEW and buy FREESAT with all the extra capacity benefits and wider choice of channels than wasting additional money on additional FREEVIEW equipment (just as the countey goes completely TV digital).

It would have been good for the government to have warned potential FREEVIEW purchasers beforehand that some of them would have to shell out a fortune in additional equipment (in most case dearer than their original box) in order to block 4G interferance. You couldn't make this up if you tried.

Just like they weren't very open about FREEVIEW LITE in most of the the areas served by relay transmitters, where many people would have opted for FREESAT if they had been made fully aware of the restricted number of multiplexes and channels in these locations.

Nedbod: The BBC A and ArqA multiplexes will move from their current channels, C62 and C61 respectively, to C50 and C49, some time in April 2013 (current plan, no specific date given). D3&4 will remain on C59 so *could* be affected by interference from 4G transmissions.

Whether your TV reception will be affected will depend on where the 4G base stations are located compared to your line-of-sight to Winter Hill, and the exact frequencies that each one uses. A 30 MHz band has been allocated for downlink (transmissions from base station to phone), from 791 to 821 MHz, in probably 5 MHz chunks (values of 10, 15 and 20 MHz are also supported, with more bandwidth providing higher bitrates, but the higher bandwidths - hence fewer channels - would means fewer cells could be fit in before having to repeat). The risk is of introducing intermodulation through too-high signals overall, though it has also been found that receivers (set-top boxes and TVs) tend to suffer poorer sensitivity when there is a loud transmission in an adjacent channel.

If a filter is required, C59 will require a shallower roll-off than for C60, but it would still be relatively steep, many dBs of roll-off over only about 8 MHz. It's possible that some filters would cost more than some Freeview equipment, but only because the equipment is now down to under £20!

The plan is for the spectrum auction winners to provide a fund for any necessary filters, and if a practical filter is not possible for this customer, to fund an alternative means of reception. There are concerns that the fund, for which £180m has been suggested as the total sum, is not large enough.

Nedbod: Thanks Mike for a very comprehensive and helpful response. I still think we should have been warned of this possibility before deciding which DIGITAL option to take. I personally would have opted for FREESAT if I had known in advance that interference was even a possibility on FREEVIEW.
