MEETING THE DATA DEMAND TIDAL WAVE: UPGRADE OF INDOOR DAS FOR LTEWhite Paper
With rapid urbanization and building densification, outdoor cell sites are increasingly inadequate to meet indoor consumption demands and expectations. Existing distributed antenna system (DAS) built for voice services on GSM and even 3G is not capable of delivering the customer’s expected data performance with a direct upgrade of base station equipment. To retain and attract customers, operators need to channel investments into indoor systems beyond outdoor rollout for 3G/4G. However, with limited CAPEX, the low hanging fruit is to upgrade important buildings with existing DAS systems to ensure they meet the required data quality of service (QoS). In the case study, we see that re-using DAS infrastructure designed for voice cannot meet the data requirements for LTE or even HSPA. The antenna must be densified by approximately 1.5 times to achieve the desired LTE high data rates.
