![]() Companies are actively working on IoT use-cases involving both NB-IoT and LTE-M. Major industry initiatives worldwide, in areas such as connected and autonomous vehicles, connected or smart homes, agriculture, robotics, smart industry, smart cities and smart energy, are exploring and investing in the potential of IoT. Among these, 362 devices support Cat-NB1 (including known variants) up from 347 in three months. In the past six months, GSA has identified 518 devices are supporting either Cat-M1, Cat-NB1 (NB-IoT) or Cat-NB2, 5% more than were in the GAMBoD database at the end of December 2020. This momentum in commercial networks is replicated in the availability of devices supporting 3GPP IoT standards. Meanwhile the number of commercially launched networks continues to grow. As of April this year, the GSA’s GAMBoD database recorded 165 operators actively investing in NB-IoT technology with a further 75 operators actively investing in LTE-M. However, this represents just the tip of the IoT iceberg. While 29 countries have NB-IoT networks only, and one country has an LTE-M network only. Of those, 34 operators have deployed/launched both NB-IoT and LTE-M. – Source: Australian Government: Antarctic DvisionĪdditional causes for the colouration include brown sediment washing underneath the ice shelf and dead marine creatures such as krill becoming trapped in the ice.Continued mobile industry commitment to the range of 3GPP-standards-based Low Power Wide Area (LPWA) technologies has been demonstrated by the continued rise in the number of networks supporting NB-IoT and LTE-MTC (LTE-M) networks and the substantial growth in the number of Cat-NB1, Cat-NB2 and Cat-M1 compliant devices.Īccording to GSA’s latest report “ NB-IoT and LTE-M: April 2021 ”, there are 136 operators that have deployed/launched NB-IoT or LTE-M networks in 64 countries. After calving, they begin eroding and the alignment of the stripes can become irregular, leading to icebergs with spectacular appearances. Crevasses high on the Antarctic plateau can fill with melt water and then refreeze, producing layering of blue ice within a white ice matrix. This is thought to be a result of melting that can occur on the continent before the bergs break off. Pure glacial ice, too, can exhibit striking colour patterns. As the bergs become fragmented and sculpted by the wind and waves, the different coloured layers can develop striking patterns. Thus icebergs broken off from the ice shelves may show layers of the pure blue-white glacial ice and greener ice formed from frozen seawater. Often, the frozen seawater contains organic matter and minerals, causing it to have a different colour and texture. Because this ice is formed from seawater, it differs from the freshwater ice of the ice shelf. Under certain conditions it can freeze to the base of the ice shelf. Because the ice shelves are very thick and are floating, the seawater beneath them interacts with the glacial ice.Īs seawater is drawn deep under the ice shelves by the oceanic currents, it becomes supercooled. The ice flows slowly to the coast and breaks off either from glaciers or from ice shelves. “Icebergs are formed from the glacial ice that has built up from snow falling on the Antarctic continent over millennia. So how does this multicolored striping happen? According to the Australian Government’s Antarctic Division: #THE INTERNET ICEBERG FULL#There’s even a full report by Internet sleuth site on the email/pics. While the location was incorrect, the phenomenon is indeed very real. #THE INTERNET ICEBERG SERIES#This image along with a series of other amazing photos of icebergs and glaciers were the subject of popular email forwards many years back, often incorrectly labeled as icebergs in Lake Michigan or Huron. In this remarkable capture we see a multicolored striped iceberg spotted somewhere near Antarctica, about 2,700 km south of Cape Town, South Africa. ![]()
