INOVA DAS Operating Manual
System Specification
4.1 System Specification
INOVA DAS is an US/Canada DAS equipment, supports 700MHz, 850MHz, 1.9GHz, 2.1GHz, 2.3GHz,
2.5GHz or 2.6GHz frequency bands, and all frequency bands are designed for extension. INOVA DAS
satisfies the following function and performance characteristics, and specifications not mentioned all
satisfy the functions and performance requests of “3GPP TS25.104”, “3GPP TS25.106”, “3GPP TS 36.104”.
INOVA DAS has the basic functions of the following.
- MHU is connected with base station by RF(wire) access, and connected to EHUB with one optic
cable. Also, EHUB is connected with ERU with Cat.7 cable, and ERU is installed in shaded area to
eliminate radio shaded areas.
-ERU receives power from EHUB through PoE++, and does not need a separate input power.
- Wireless quality of CDMA, UMTS, LTE, TD-LTE service is equal as base station wireless quality.
- When moving terminal enters neighboring base station, this system supports continuous handover.
