Title: Innovations of Tomas Sandin
Introduction
Tomas Sandin is a notable inventor based in Stockholm, Sweden. He has made significant contributions to the field of telecommunications, holding a total of 4 patents. His work primarily focuses on enhancing communication systems, particularly in the context of CDMA networks.
Latest Patents
One of his latest patents is titled "Accommodating packet data loss at base stations interfacing between a packet switched network and a CDMA macrodiversity network." This invention involves operating multiple base stations in CDMA macrodiversity mode to effectively communicate messages to mobile stations. If a message is successfully received by one of the base stations via a packet network, it is then relayed to the mobile station through the air interface using CDMA. If the message is not successfully communicated, the base station refrains from sending any message to the mobile station.
Another significant patent by Sandin is "Transmit power control in a radio communication system." This patent describes methods for controlling the power levels of transmitted signals in telecommunication systems. For instance, a remote terminal measures the quality of a received signal by determining the frame error rate or the bit error rate. It then reports this quality measurement to the network, which adjusts the transmit power levels of the signal transmitters accordingly. This approach allows for faster power control methods to be combined with slower methods for downlink transmissions in various communication scenarios.
