Mae Ofcom yn dilyn egwyddorion data agored, gan sicrhau bod y data rydym yn ei greu a’i gasglu ar gael i’r cyhoedd lle bo modd.  

Data agored yw data y gall unrhyw un gael gafael arno, ei ddefnyddio neu ei rannu.

Mae data agored Ofcom yn gymysgedd o ddata gan, neu am, y cwmnïau rydym yn eu rheoleiddio yn y sector cyfathrebu, yn ogystal â’r dinasyddion a’r defnyddwyr sy’n eu defnyddio. Rydym hefyd yn defnyddio ac yn rhyddhau data arall nad yw’n agored.

Mae’r holl ddata sydd ar gael ar ein gwefan ac ar byrth eraill yn destun trwydded.

Lle gallwn sicrhau bod y data ar gael ar sail agored, rydym yn defnyddio’r Drwydded Llywodraeth Agored, sy’n rhoi rhyddid i ddefnyddwyr ddewis sut maent yn dewis defnyddio’r data, yn destun amodau.

Mewn rhai achosion, rydym wedi sicrhau bod data ar gael ond mae cyfyngiadau ar sut y gellir ei ddefnyddio; er enghraifft, pan fydd rhywfaint o’r data hwnnw neu’r data i gyd yn eiddo i drydydd parti. Yn yr achosion hyn, rydym yn nodi yn y drwydded ar ba sail yn union y gallwch chi ddefnyddio’r data.

Mae’r dudalen hon yn cynnwys dolenni i’r rhan fwyaf o’n setiau data sydd ar gael gyda thrwydded Data Agored.

Gallwch weld cyhoeddiadau data eleni ar y calendr datganiadau ystadegol.

Mae rhai o’r setiau data hyn hefyd ar gael ar brif dudalennau eu prif gyhoeddiad, fel Cysylltu’r Gwledydd 2021 a’n hadroddiadau cwynion am delegyfathrebiadau a theledu drwy dalu.

Gallwch hefyd ddod o hyd iddynt ar borth data.gov.uk, ochr yn ochr â setiau data gan holl adrannau llywodraeth ganol a llawer o gyrff eraill yn y sector cyhoeddus ac awdurdodau lleol.  

Rydym yn dal i ddatblygu ac adeiladu ein dull o ryddhau data agored. Os oes gennych chi unrhyw sylwadau am y dudalen hon neu ein dull gweithredu yn gyffredinol, anfonwch neges ebost at open.data@ofcom.org.uk.

Os oes gennych chi sylwadau neu ymholiadau am set ddata benodol sydd ar gael ar y dudalen hon, neu os ydych chi’n fodlon rhannu’r ffyrdd rydych chi wedi defnyddio’r data, anfonwch neges ebost at open.data@ofcom.org.uk. Nodwch at ba set ddata rydych chi’n cyfeirio a chofiwch gynnwys y dolenni lle bo hynny’n berthnasol.

Trosglwyddyddion radio darlledu: paramedrau technegol  

Mae’r wybodaeth ganlynol yn cynnwys manylion paramedrau technegol yr holl drosglwyddyddion VHF, MF a DAB analog (gan gynnwys gwasanaethau ar amlblecsau) sydd ar yr awyr ar hyn o bryd. Mae paramedrau mewn defnydd yn cael eu cynnwys yn bennaf ar gyfer gwrandawyr a gosodwyr erialau a allai fod eisiau gwybod mwy am natur y signalau maen nhw’n eu derbyn ac o bosibl optimeiddio eu herial yn unol â hynny. Mae’r paramedrau uchaf a ganiateir (o fewn telerau pob trwydded) ar gyfer gwasanaethau analog hefyd yn cael eu cynnwys er budd y rhai, yn bennaf o fewn y diwydiant, sy’n dymuno gwneud cyfrifiadau, yn enwedig ynghylch ymyriant, at ddibenion cynllunio darpariaeth. Bwriedir i’r fformat fod yn fwy hwylus i’w lwytho i lawr a’i drosglwyddo i gronfeydd data arbenigol, nag i’w gyflwyno.

Bydd data TxParams yn cael ei ddiweddaru’n rheolaidd wrth i drosglwyddyddion newydd gael eu hychwanegu, eu haddasu neu eu hatal.

Profiad gwylwyr o dderbyniad teledu

Mae’r ddogfen hon yn adrodd ar ymchwil ynghylch pa mor aml mae ymyriant neu amhariad ar wasanaeth gwylwyr teledu darlledu, ar draws pob llwyfan, yn ogystal â’r mathau o ymyriant y mae gwylwyr teledu daearol digidol yn ei wynebu wrth ddefnyddio erial ar y to. Ei nod yw deall a yw gwylwyr teledu daearol digidol (sy'n derbyn darllediadau teledu drwy erialau ar ben y to) yn gwybod â phwy i gysylltu pan fyddant yn cael problemau â derbyniad teledu, ac mae’n ceisio gwerthuso lefelau bodlonrwydd y gwylwyr yr effeithir arnynt â’r cymorth maen nhw’n ei gael.

Cwynion am delegyfathrebiadau a theledu drwy dalu

Cwynion a gofnodwyd gan Ofcom yn erbyn y darparwyr teledu drwy dalu a thelegyfathrebiadau mwyaf. Ers mis Mai 2015 rydym wedi rhyddhau’r setiau data chwarterol hyn mewn fformat csv.

Bwriad yr wybodaeth hon yw helpu defnyddwyr i wneud penderfyniadau mwy gwybodus. Rydym yn credu bod cyhoeddi gwybodaeth o’r fath yn ddefnyddiol i ddefnyddwyr, yn enwedig y rheini sy’n meddwl am newid darparwr neu brynu gwasanaeth newydd. Rydym hefyd yn credu bod cyhoeddi gwybodaeth am faint o gwynion a gaiff darparwyr penodol yn cymell darparwyr i wella eu perfformiad.

Children's media literacy

Annual report on children's media literacy in the UK. This report provides detailed evidence on media use, attitudes and understanding among children and young people aged 5-15, as well as detailed information about the media access and use of young children aged 3-4.

The report also includes findings relating to parents' views about their children's media use, and the ways that parents seek - or decide not - to monitor or limit use of different types of media. It is a reference tool for industry, stakeholders and consumers. It also provides context to the work Ofcom undertakes in furthering the interests of consumers and citizens in the markets we regulate.

UK radiowave propagation measurement data for frequencies below 6 GHz

This radiowave propagation measurement data was collected by Ofcom in seven areas of the UK between 2015 and 2018. It is representative of the UK’s diverse topography. Measurements were made at six frequencies between 400 MHz and 6 GHz. All equipment was carefully calibrated allowing the basic transmission loss to be calculated. Ofcom is using the data to assess and improve UK specific performance and applicable frequency ranges of propagation prediction methods, including ITU-R P-series Recommendations.

We are making this data available so that academia and industry can benefit from the data in analysis of their own propagation models. A document, UK radiowave propagation measurement data for frequencies below 6 GHz (PDF, 4.1 MB), provides information on the technical parameters and describes the format of the measurement data files.
