MIL-STD – Wikipedia
If downlink power decreases, ITA then automatically and dynamically decreases the link data rate using more robust waveforms to maintain the link connection. A number of features and choices remain when considering wireless networking equipment like the satellite communications modems that form the backbone of many wireless networks. This page was last edited on 20 Juneat For well-groomed transponders, PCMA can be of value, but to a lesser degree.
The mandatory use of these standards will aid significantly in achieving standardization and result in improvements in availability, maintainability, reliability, and supportability. Retrieved January 12, According to the DoD the MIL-STD series “contains current tactical communications, technical standards and design objectives…[this series includes] appropriate unclassified design objectives and tactical communications systems technical standards…[and] Appropriate communications-electronics systems standards and design objectives developed under joint projects…[which are] integrated in the tactical communications standards.
Currently the DoD is placing its emphasis “on the development of common standards for tactical and long-haul communications the MIL-STD series. Providing an open standard for this enhanced forward error correction technique means that efficiency and interoperability can finally coexist.
Interoperability does not mean mil-stv-188-165b SATCOM users should be faced with only a plain vanilla set of choices for their networking, rather that those choices should meet an underlying ability to interoperate with other similar network devices. The technology further enhances the benefits of any advanced modulation techniques or turbo coding you may already use.
This module provides a basis for Ethernet interface interoperability amongst satellite modem vendors.
To reach that objective, DoD policy includes a reduction in the number of available wireless waveforms and corresponding network hardware.
Department of Defense looked to develop a series of standards that would alleviate the problem. A principal objective of recent U. The technology uses an adaptive self-interference cancellation technique to subtract the transmitted signal and recover the desired signal. Department of Defense telecommunication transmission policy is to simplify its integrated wireless networks.
Faced with “past technical deficiencies in telecommunications systems and equipment and software…that were traced to basic inadequacies in the application of telecommunication standards and to the lack of a well defined…program for their review, control and implementation”, the U.
The manner in which a satellite modem converts digital data to analog signals for delivery over the air and then retranslates that data back to a digital format must be the same on each side of a satellite link. They are appropriate only when certain conditions apply: Increased symbol rates to 60 Msps providing single carrier data rates up to Mbps.
Views Read Edit View history. The bottom line advantage of the MD efficiency is that more carriers can be placed on a single satellite transponder and those carriers can be better utilized, enabling more warfighters to gain access to more data when and where they need it.
Demonstrations of the modem have shown the value of the new modulation and coding choices. Together, the features maximize overall network throughput across the satellite link when little or no margin is needed. Though this new standard is often thought of as catching the military up to commercial standards and technology, the new B standard is actually enhanced beyond pure commercial technology.
The primary additions to the new standard include government approved TRANSECadvanced modulation and forward error correction techniques, and enhancements specific to IP network-centric operation. The objective is to field fewer types of wireless network devices, while providing improved network interoperability to accommodate the emergence of Internet Protocol IP as a connectivity standard.
According to the DoD the MIL-STD series contains “technical standards and design objectives which are common to both the long haul and tactical communications systems. Known turbo codes at reasonable block size and complexity can come quite close to the Shannon channel capacity limit within about 1 to 2 dB. All articles with dead external links Articles with dead external links from May Articles with permanently dead external links.
However within common networks, interoperability with efficiency is the goal. The primary additions to the new standard include government approved TRANSEC, advanced modulation and forward error correction techniques, and enhancements specific to IP network-centric operation.
For any DoD Agency to get a waiver to receive an item that deviates from the standards they also must apply to the JSC. Documents with three digit numbers followed by a letter of the alphabet indicate that they are mil-std-188-165b of an older version of that document.
Using different modems that have an open-standard waveform, but proprietary baseband interfaces is just as ineffective as using two different proprietary modems.
Link budget analysis can determine feasibility, link configuration, and the possible overall savings of power and bandwidth with PCMA. Military of the United States standards Telecommunications standards Videotelephony.
From Wikipedia, the free encyclopedia. Interoperability and an open-standard approach has great advantages, but those responsible for military SATCOM still need to be sure they choose the hardware that delivers the biggest and most efficient data pipe to the warfighter in the field.
