Chunghwa Goes Flat

8:30 AM -- Nokia Networks has chalked up another customer to test its flat 3G radio access network (RAN) solution. As part of a €72 million (US$114 million) network upgrade contract, Chunghwa Telecom Co. Ltd. (NYSE: CHT) will try out NSN's Internet High-Speed Packet Access (I-HSPA). (See NSN Wins in Taiwan, 3G Flat Attack, NSN Flattens 3G Network Design, and Rouanne Has Ericsson in His Sights.)

Chunghwa -- which is the first operator in the Asia/Pacific to test NSN's flat RAN solution -- joins a growing list of operators that are looking to implement all-IP architectures before the advent of so-called 4G technology Long-Term Evolution (LTE). NSN's other I-HSPA customers are Stelera Wireless and TerreStar Corp. in the U.S. and T-2 in Slovenia. Meanwhile, Mobilkom Austria AG & Co. KG has trialed the solution. (See NSN Deploys HSPA and Terrestar Picks I-HSPA.)

Flat RANs and other approaches to all-IP architectures are covered in the Heavy Reading report, "Flat IP Architectures in Mobile Networks: From 3G to LTE."
