This paper presents a case study of the proposed digital television based WiMAX wireless network to provide broadband Internet service in the suburban/rural area of BacNinh province, Vietnam. Advantages of the combination between digital television and WiMAX in the UHF broadcasting bands are discussed and compared with existing WiMAX in the microwave frequency bands. Commercially available equipments for both base-station and subscriber station are evaluated and incorporated in the link budget study and simulation.
