Thailand’s second- largest mobile operator, dtac, asked Ericsson to transform its business and swap out the aging network equipment ,enabling an upgrade from 2G to 3G and LTE. With the goal of building the best network in Thailand, dtac was able to substantially grow its subscriber base, while also increasing customer satisfaction and preparing its operation to better manage rich data.
Human exposure to the radio frequency electromagnetic fields (EMF) emitted by radio base stations (RBS) is proportional to the transmitted power. Thus, knowledge of actual power levels is key for a correct estimate of the actual EMF exposure. In this study, downlink output power distributions for RBSs in a 4G LTE mobile communication network have been determined. By extracting data using the operations support system (OSS) of the network, statistics were obtained based on 24 hours measurements for more than 5000 RBSs. The network measurement approach was verified with in-situ power density measurements. It was found that the actual output power levels are significantly below the theoretical maximum. For high-traffic periods, the 90th percentile transmitted power was found to be about 12% of the theoretical maximum.
LTE (long term evolution) provides the fastest mobile broadband services commercially available today. But have you ever wondered how it works? Ericsson has created a video that explains not only how LTE works but also what benefits it has for the end-user.
Smartphone users want their apps to work – anywhere, anytime. Ericsson’s app coverage concept helps operators ensure that they deliver real performance to their subscribers.
Despite the global growth in broadband, it is not yet widely used in the public safety sector. Work is currently ongoing to identify the best way forward. On the technical side, the standardized LTE technology has been widely accepted as a suitable base for public safety broadband communication due to excellent technical characteristics such as high data rates and well-planned features for prioritization and control of Quality of Service.
