INTRODUCTION The Los Angeles Unified School District (LAUSD/the District) is an educational institution serving the second largest student population in the country. It is committed to providing the highest quality instructional services to a constituency whose needs range broadly in both scope and complexity. As with other educational institutions, the District’s resources and budget are limited. To meet the IT needs of its constituency within these constraints; LAUSD pursues long- term solutions from a foundation of defined standards and proven interoperability. The District’s Information Technology Division (ITD) has developed this document as a resource for parties seeking to provide products and/or services to the District. The following sections provide an overview of District IT infrastructure to assist prospective vendors in providing more comprehensive proposals and solutions that maximize use of existing District technology assets and investment. The information contained within this document represents a snapshot in time. The District’s environment is dynamic, and it is important to note that while the District has made a substantial effort to ensure the accuracy and completeness of this information, ongoing change and the increasing scope of LAUSD technology infrastructure may result in infrastructure modifications not reflected by this document. The District makes no warranties as to the accuracy, completeness, or timeliness of the information contained in this document. Prospective vendors should directly validate any information in this document prior to using the information as the basis for decisions with a material impact. The following sub-section provides a high-level overview of District IT infrastructure. It contains a brief description of the underlying structure and scope of IT used within LAUSD to act as a foundation for the detail provided in subsequent sections. 2.1 District IT at a Glance At the highest level, District IT architecture is comprised of three tiers: a central core, distribution layer, and edge locations consisting of over 1200 schools, adult education facilities, child development centers, administrative offices, and other functions spread across roughly 700 square miles.

When the operation is quite small, communication among team leaders may be easily done by just walking over to the other person and having a face-to-face conversation. However, when the operation is larger, using radios may be more effective. This course is intended to be a basic introduction to several radio classes/services. It is by no means intended to be thorough for any of the radio classes discussed. There is much more that can be learned about each radio class through further study.

The meeting will be in the annex next to the sanctuary building. Things get underway at 7:30 p.m. when Doris WB9VDT bangs the gavel. -30- This Month’s Program: The program for the May BARS meeting will be a video presentation on operational amplifiers entitled "Op- Amps 101." The basic features of op-amps will be reviewed, and the common ways these amplifiers can be configured will be examined. -30- Hurricanes, Catastrophes, and Disasters (Part 2) Mark WB9UJS Last month we started off looking at Ham frequencies, U.S. Coast Guard frequencies, and FEMA frequencies used in disaster situations. This month we will wrap it up with business band channels, Family Radio Service frequencies, military squad radios, the county trunked system, and some others. There are other radio services that can play a communications role in disaster situations. The General Mobile Radio Service (GMRS) has frequencies in the UHF part of the spectrum, close to the 440 MHz Amateur Radio band. Often this allocation is referred to as “business band”. Some other frequencies that will likely yield a lot of traffic are the GMRS (business band) and Family Radio Service (FRS) frequencies.

  • Primer on FCC Licensing Multi Use Radio Service (MURS)
    Primer on FCC licensing The origins of personal 2-way radio go back over 50 years to a service known as Class A Citizens Band, now known as GMRS (General Mobile Radio Service) with several changes including a RESTRICTION AGAINST COMMERCIAL USE. The band most of know as CB operates in the 27 MHz band (Originally known as Class D Citizens Band) and is now used mostly by over the road truckers (and those who want to talk to them). FRS (Family Radio Service) is ultra low power short-range service primarily for personal use although business related communications is permitted. Falcon Direct specializes in serving the needs of business, institutional, and governmental users. Accordingly, we do not promote the use of FRS radios (generally ineffective for the needs of our users) or GMRS (illegal for commercial or governmental use). However, if you have a need for GMRS radios, we do offer the full line of Midland GMRS radios. You can review the products on line at www.midlandradio.com , and then give us a call at 1.800.489.2611 for special discounted pricing. If you have a need for FRS radios, you can find them at any discount store. Commercial, institutional, and governmental users must have an FCC license or in some cases, permission to use services provided by an authorized FCC licensee. If you have a commercial application for wireless communications, you will likely need professional assistance in preparing and submitting your application to the FCC. One of the better ones is Josie Lynch. You can call here at 301-309-2380.

  • Alternate Methods of Communication Waller County ARES Training Material Used with Permission from Christine Smith, N5CAS
    Alternate Methods of Communication Waller County ARES training material used with permission from Christine Smith, N5CAS. There will be times when some form of communication other than Amateur Radio might be more appropriate. Remember that your job is to communicate. Here are some possible situations: The need to communicate with non-ham volunteers or emergency management personnel. The transmission of sensitive or lengthy information. Communication with the public. The Amateur Radio equipment has failed or is not available. Interference is blocking use of Amateur Radio frequencies Legal Thoughts Regarding Licenses: 1. Some radio services require licenses, and others do not. In a true emergency as defined by the FCC, this may not be a problem. FCC rules gives anyone permission to use "any means necessary" to communicate in order to protect life and property -- but only when no other normal means of communication is possible. Don’t assume that this means you can just modify your radio and call for help on the local police frequency the next time you see a car crash on the highway. If you are in a position to save someone's life or property, be sure you are ready to defend your actions - and possibly lose - before your transmission. 2. Other services, such as GMRS, require a license that is relatively easy to obtain. If you plan to use licensed radios, you need to obtain a licenses well before any emergency and keep it current. If you own a radio, but no license, a judge could claim pre-meditation if you use it and disturb licensed users.

    ALABAMA Tactical Interoperable Communications Field Operations Guide (ALA-FOG) Version 1.0 dated March 2012 For Official Use Only Letter of Introduction The Alabama Statewide Tactical Interoperable Communications Field Operations Guide (ALA-FOG) is a collection of technical reference material to aid Communications Unit personnel in establishing solutions to support communications during emergency incidents and planned events. The ALA-FOG includes information from the Statewide Communications Interoperability Plan (SCIP), Regional Tactical Interoperable Communications Plan, and data from other Alabama communications documents; formatted as a pocket-sized guide. The ALA-FOG contains state and national interoperability channels. These channels should be programmed into all public safety radios in the appropriate frequency band. If geographic restrictions on some channels preclude their use within the State of Alabama, they may offer an interoperability option when responding out of territory where the restrictions do not apply. Please send updates, corrections, or comments about the ALA- FOG or requests for additional copies to [email protected] . Thank you, Charles R.

Miller as submitted in RM-11392 for consideration by the Commission. 28 29 In lieu of reducing allowable bandwidths for various digital modes of operation, it is important that the 30 Commission continue to support technical innovation within the amateur radio service. The Commission has long 31 held the published viewpoint, quoted in part from PR Docket 88-139, as follows: 32 33 34 “We wish to recognize and encourage the experimental nature of 35 the amateur service. It is appropriate to avoid, to the extent possible, 36 placing in the Rules detailed regulations and specifications for the 37 configuration and operation of various amateur communications 38 systems. Such regulations and specifications would reduce the 39 flexibility that is the hallmark of a service free to branch out and 40 follow an infinite number of paths… This enables amateur radio 41 operators to utilize their individual stations in creating and 42 pioneering communications systems that are limited only by their 43 personal interests, imagination, and technical skills.” 44 45 46 The recommendation and bullet-points to follow will outline the basic position of this paper which this author is 47 submitting in response to RM-11392.
