ACU-M™ Improving In-Building Communications
Application Note: AN-2306-2 ACU-M™ Improving In-Building Communications Purpose This application note will describe methods in which the Raytheon’s ACU-M can be used to improve in-building communications. The application note will discuss permanent and temporary methods at which different devices can help increase the ability to transmit or receive land mobile radio communications from within a building, below-grade, or behind obstructions. Introduction Land mobile radios, whether used in vehicles or as handheld portables, are an important tool used everyday by first responders to make their jobs safer and more efficient. In the most part, these radio systems function as designed, and serve the end-user with reliable communications. However, when the duties of a first responder require them to enter a building, or operate below- grade during emergencies, the ability of their radios to communicate to the base, incident command or dispatcher may become an issue. One physical constraint of land mobile radio communications is its inability to transmit and receive radio waves through obstructions such as buildings or below-grade structures. The failure of a land mobile radio to transmit and receive communications from within a building or below-grade has cursed radio users since the beginning of land mobile radio communications (see Figure 1).

The FCC Filing
Dr. Theodore S. Rappaport, PE PO BOX 888 Riner, Virginia 24149 [email protected] November 10, 2018 Commissioners Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear FCC Commissioners: This is a notice of ex parte, based on email communication I had with the CTO of the FCC, Dr. Eric Burger, on November 8, 2018, his reply on November 10, 2018, and my reply on November 11, 2018. The email communication is centered around a posting that appeared on the FCC ECFS system on November 7, 2018, and is part of an ongoing proceeding at the FCC, NPRM 16-239, that I and thousands of others view as a direct threat to the national security interests of the United States, as well as being detrimental to the hobby of amateur (“ham”) radio. Public comments made in FCC’s NPRM 16-239, and in FCC proceedings RM-11708, RM-11759, and RM-11306 proposed by the American Radio Relay League, show the vast number of rule violations and national security threats that continue to go unaddressed by the FCC. Commenters such as me view the lack of FCC acknowledgement of these problems as jeopardizing the safety of US citizens. NPRM 16-239 attempts to remove a limit on the baud rate of High Frequency (HF) shortwave transmissions, without first addressing ongoing rule violations pertaining to proper usage of the amateur radio service, the use of obscured, private messaging which is forbidden in Part 97 rules and creates national security concerns, as well as other violations. If allowed, NPRM 16-239 would perpetuate the current violations, and would authorize obscured transmissions of unlimited bandwidth over the global airwaves, further increasing the danger to our national security, since these transmissions cannot be intercepted or eavesdropped by other amateur radio operators or the FCC. -

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. -
Citizens' Band (CB) Radio Spectrum Use – Information and Operation
Citizens’ Band Radio equipment– information and operation Citizens’ Band (CB) radio spectrum use – information and operation Of 364 Guidance Publication date: March 2018 Citizens’ Band Radio equipment– information and operation Contents Section Page 1 Regulatory and equipment information 1 2 Frequently asked questions 5 3 CB operating practice 8 Citizens’ Band Radio equipment– information and operation Section 1 Regulatory and equipment information Citizens’ Band (‘CB’) radio 1.1 Citizens’ Band (‘CB’) radio operates in the 27 MHz band. It is a short-range radio service for both hobby and business use. It is designed to be used without the need for technical qualifications. However, its use must not cause interference to other radio users. Consequently, only radios meeting certain specific requirements may be used. These are described below. How Ofcom authorises the use of CB radio 1.2 Ofcom seeks to reduce regulation, where possible. In 2006, we therefore made exemption regulations1, removing the need for a person to hold a licence to operate CB radio equipment using Angle Modulation (FM/PM). 1.3 In 2014, Ofcom made further exemption regulations2, which permitted the operation of CB radio equipment using two additional modes of Amplitude Modulation (AM) - Double Side Band (DSB) and Single Side Band (SSB). This followed an international agreement3 made in 2011.”. 1.4 CB users share spectrum in a frequency band used by the Ministry of Defence (MOD). CB users must therefore accept incoming interference caused by use of this spectrum by the MOD. 1.5 CB radio equipment must be operated on a 'non-interference’ basis. -

Choos- ing just one from the variety of radio models is a challenge! The • Manufacturer’s Directory good news is that most commercially manufactured Amateur Radio equipment performs the basics very well, so you shouldn’t be overly concerned about a “wrong” choice of brands or models. This guide is intended to help you make sense of common features and decide which are most important to you. We provide explanations and defini- tions, along with what a particular feature might mean to you on the air. This publication is aimed at the new Technician licensee ready to acquire a first radio, a licensee recently upgraded to General Class and wanting to explore HF, or someone getting back into ham radio after a period of inactivity. A technical background is not needed to understand the material. ABOUT THIS PUBLICATION After this introduction and a “Quick Start” guide, there are two main sections; one cov- ering gear for the VHF and UHF bands and one for HF band equipment. You’ll encounter a number of terms and abbreviations--watch for italicized words—so two glossaries are provided; one for the VHF/UHF section and one for the HF section. You’ll be comfortable with these terms by the time you’ve finished reading! We assume that you’ll be buying commercial equipment and accessories as new gear. -
