iDAS

Product Description

Due to the feature of 3G application the most of the traffic will be happened in the indoor scenario. iDAS is one of the solution of Digimoc Telecom Technology for this application. iDAS can be used in the railway station,airport,shopping mall, office building, conference hall, gymnasium,etc. With its excellent features ,iDAS can supply a good coverage for TD-SCDMA indoor application
iDAS system consists of three modules,IIU,IHU and IAU. IIU is a IF Interface Unit and used to interface with NodeB via IF ,RF,or baseband signal. IHU is a IF Expending Unit and IAU is a remote RF module. The connection between IIU and IHU can be coaxial cable or optical fiber,and the one between IHU and IAU can be cable or CAT-5E/6 STP line.One IIU supports 4 IHUs, and one IHU for 8IAUs. If the coverage area is not so large, the IIU can be saved
