The current Common Data Link, the U.S. military's secure communications protocol created in 1991, operates at data rates of up to 274Mbps. To boost that speed, the Defense Advanced Research Projects Agency is inviting input on creation of a new wireless communications platform that would match the weight and power of the current CDL. DARPA has announced that a "proposer's day" will be held next month to brief participants on the 100G program, which aims "to design, build, and test a communications link with fiber-optic-equivalent capacity, long reach, and high availability in airborne-to-airborne and airborne-to-ground configurations that can serve as a deployable data backbone in a military communications network."The goal is to utilize airborne assets to provide high-capacity data streaming over 100 kilometers for air-to ground links and 200km for air-to-air links, the agency said today.
"Providing fiber-optic-equivalent capacity on a radio frequency carrier will require spectrally efficient use of available RF spectrum," Dick Ridgway, DARPA program manager, said lovecases floral art iphone x case - white in a statement, "100G plans to demonstrate how high-order modulation and spatial multiplexing can be synergistically combined to achieve 100 Gigabits per second with the size, weight and power needed for a deployable system, We believe that to achieve the program's goals requires the convergence of telecommunications system providers and the defense communications tech base."DARPA said one of the central challenges to the platform will be weather, The 100G backbone must provide tactically relevant throughput and link ranges through clouds, rain, and fog..
The Defense Department agency is soliciting input on a wireless communications backbone that would provide high-speed streaming for air-to-ground and ground-to-ground links over long distances. Defense researchers are looking to update the wireless platform currently used for military communications to deliver 100Gbps connections. While fiber-optic cables provide the long-haul backbone for most data and voice communications networks without issue, radio signals often face electronic interference and degradation over long distances, resulting in reduced communications efficiency to soldiers in the field.
Here's a video to show you what the process looks like on an Android device, This holiday season, send a Square gift card for the local bookstore or coffee shop to a friend or family member, Here's how, The ability send and process gift cards were recently added by Squareas an additional service for its merchants, The process is simple, but requires you to download and install the Square Wallet app (iOS, lovecases floral art iphone x case - white Android) on your smartphone, The best part about sending a Square gift cards is that the recipient doesn't even have to own a smartphone, The recipient of the card will be able to add the gift card to their Square Wallet account, or print out the card (with a QR code) and redeem it at the local business, Square merchants can then use the Square Register app to process the gift card payment..
Huawei is a company that's known in the U.S. for making inexpensive, entry-level handsets. Inexpensive is good, since it reduces the barrier to entry. But in the case of the Huawei Ascend Y, some odd decisions will stand in the way. The handset runs on the Gingerbread version of the OS; that's three steps behind the absolute most up-to-date version (4.2), and two steps behind today's most-anticipated updates (4.1). The Ascend Y has one 3.2-megapixel camera, which lacks both a flash and auto-focus. Outdoor shots are the best, while indoor shots quickly turn grainy.
