Reports suggest Virgin Media is planning to trial 4G services in a number of UK cities, following the lead of rivals such as O2 and BT.
According to the Register, the cable specialist is dropping fibre-connected LTE Small Cells into urban areas, in a bid to assess the logistics of establishing decent coverage.
This comes after Virgin Media conducted a single-cell trial in Oxford Street in December.
The Register suggested the broadband provider may be gearing up to bid for 2.6GHz radio spectrum in the autumn, paving the way for super-fast mobile broadband.
However, Virgin Media has remained silent on its future plans.
The firm already offers mobile services using Everything Everywhere's network, and could well offer 4G services on this platform.
But equally, the firm could decide to invest in its own mobile infrastructure.
Virgin Media recently announced that its fibre broadband network is now accessible to more than ten million UK homes and businesses.
