Cisco Systems and Palestinian telecommunications firm PalTel said on Saturday that the US internet networking company will help build telecoms infrastructure in the West Bank and Gaza. Both companies signed a memorandum of understanding to cooperate at a short ceremony on the sidelines of a World Economic Forum meeting in Jordan. Under the deal, Cisco, a world leader in networking for the internet, will provide PalTel with an advanced internet protocol-based infrastructure that would allow the Palestinian firm to expand both its fixed and mobile telephone lines.
