Sharing bookmarks–another route other than wikis is to have students set up accounts on del.icio.us or Furl or Google Notebook, because these tools not only allow students to bookmark their findings, but to share their bookmarks with other students. Diigo not only allows students to bookmark their sites, but annotate them, clip them, and share them on a blog, email, or album. Bookmarking a collection of sites that they can use later conveys the idea that the learning is ongoing, that they can “add to” what they have found later, in a way that a set of notecards or a bibliography doesn’t, because they seem more “final” and product oriented. And these sites allow them to network and learn collaboratively from one another.
deanna_briggs on 02 Dec 20Passive Intermodulation (PIM) is a growing concern among mobile network operators looking for maximizing their network's capacity, data rate, reliability and Return on Investment (ROI) with the deployment of 5G wireless networks. But what is exactly PIM? When two or more frequencies are mixed in a non-linear way in a passive circuit, an interference is generated and is known as PIM. The performance of a network can be adversely affected if the interference collides with uplink receive frequencies of an LTE or 5G network, generating -100dBm or higher intermodulation signals. Lowering the level of PIM, operators can achieve better capacity and network coverage.
