Kaohsiung County Broadband Mobile Network

Since 2005 the Taiwanese government has invested over

Multimedia transmission link protocol-a proposal for digital information transmission in HFC cable systems

1.2 billion into the M-Taiwan program to bolster Taiwan’s broadband mobile communications industry and infrastructure. In addition to building a fiber backbone and providing R&D grants for developing new technologies and novel applications, it has also co-funded the constructions of four large-scale test networks. The Kaohsiung County broadband mobile network is the largest one, which consists of four major subsystems: (1) a mobile WiMAX wireless network that includes 90 base stations; (2) WiFi hot zones in three remote townships to provide on-line job training and Internet access to the indigenous residents; (3) a broadband IP network that provides VoIP and Internet data services to the county government and 27 township offices and their affiliated agencies and schools; and (4) a host of application services that include M-government, M-life and M-learning. This paper gives an overview of the system architecture, the employed technologies, the application services, test results and challenges.

The modern hybrid fiber coax (HFC) CATV cable plant offers an excellent high-speed digital transmission medium between the CATVs headend and individual homes. Cable companies are laying high-capacity, high-speed digital backbone networks connecting their headends and the outside world together. Therefore, if we could design an access network via the HFC cable plant to the backbone network then we would have a complete information super-highway system. This is the motivation for our work.
