Alfa, a Lebanese mobile operator managed by Egypt’s Orascom Telecom, has announced the launch of Lebanon’s first commercial 4G LTE-Advanced (LTE-A) network in partnership with Nokia of Finland. The new network enables Alfa to offer its subscribers significantly higher download speeds of up to 262.5Mbps for accessing high-definition video and other data-intensive applications. A press release adds that the LTE-A network implementation is enabled by carrier aggregation technology, which combines two frequencies in order to significantly improve throughput and spectral efficiency. For Alfa, Nokia combined 20MHz on the 1800MHz frequency band with 15MHz on the 800MHz band. The release continues that mobile data users currently exceed 74% of Alfa’s subscriber base.
