HELSINKI, Nov 11 (Reuters) - TeliaSonera (TLSN.ST) picked Nokia Siemens Networks [NSN.UL] and Ericsson (ERICb.ST) for the rollout of its next generation LTE network in Finland starting next month, the Nordic telecoms group said on Thursday.
Earlier this year, TeliaSonera picked the same two companies to supply its faster networks using the Long Term Evolution (LTE) technology in Sweden and Norway.
Marek Hintze, chief of TeliaSonera's mobile operations in Finland, said the company could also use agressive Chinese vendors Huawei [HWT.UL] and ZTE (0763.HK) in future expansions.
"What's slowing us down is the availability of modems," Hintze told a news conference, adding many companies had unveiled LTE modem plans, but so far only Samsung Electronics (005930.KS) was supplying them.
Companies such as Ericsson and Nokia Siemens are in a firece battle with Chinese firms to win orders for LTE equipment, which offers faster data connections for operators, as landing a critical mass of orders makes it easier to win future deals.
Hintze said in addition to LTE buildout, TeliaSonera would next year increase investments into its Finnish 3G network.
"It is clear that the total investments next year will be higher," Hintze said.
In 2010 the group is set to spend around 200 million euros ($275 million) in Finland. ($1=.7253 Euro) (Editing by Will Waterman)
