LONDON/FRANKFURT, Nov 3 (Reuters) - German cable firm Unity Media is planning a 500 million euro ($732 million) initial public offering (IPO) in December, people familiar with the matter said, as Europe's IPO market begins to warm up.

Europe is lagging far behind Asia and the United States in IPO activity but could see a wave of deals next year, bankers said. [ID:nLM175549]

Unity Media's deal, which would follow two recent major IPOs in the region -- top Polish utility PGE's $2.2 billion offering and Dutch insurer Delta Lloyd NV's (DLL.AS: Quote, Profile, Research) 1 billion euro ($1.5 billion) listing -- could take Europe's IPO volume this year to around $5.5 billion, according to Thomson Reuters data.

That would bring Europe's share of global IPO volume close to 7 percent, up from 1.8 percent in September.
