With the help of Qualcomm (QCOM) silicon supporting the LTE-Advanced standard, Samsung (SSNLF.PK) is set to release a version of the Galaxy S4 that can deliver twice the download speeds of current models. GigaOm isn't too impressed, pointing out Samsung appears to be adopting a simple version of LTE-Advanced that offers a technique for pooling spectrum bands (carrier aggregation). Meanwhile, Reuters points out many analysts have lowered their S4 sales estimates to ~7M/month from a prior ~10M/month, following order cut reports. That could be pressuring Universal Display's (PANL -1.5%) shares. Qualcomm has an early lead in supporting LTE-Advanced, but Broadcom (BRCM) and Nvidia (NVDA) aren't far behind (I, II).
