6 617-770-0212 WWW.RADIOSHOP.COM RADIO SELECTION GUIDE Radio Selection Portable and Mobile Radios USER NEEDS There are three basic factors you need to consider when selecting which radio is right for you. 1. Number of Users / Channels 2. Frequency Band 3. Features NUMBER OF USERS / CHANNELS The number of individual users as well as the number of talk groups you need to maintain determines the number of channels you will require in a radio. For example, if you want a certain department to maintain its own talk group, it would require a dedicated channel for that department. If two or more individuals need to maintain private communications, a dedicated channel would be required. It is not uncommon to have multiple channels within a department for special projects where more than one operation or event is occurring simultaneously. In addition, the use of digital technology increases the capacity of your system by dividing your existing channels into two time slots. This enables you to double the number of users on your system without the need for additional infrastructure equipment. Lastly, when making decisions regarding the number of channels you require, it is very important to keep future expansion in mind. FREQUENCY BAND For most general applications, there are 3 categories of frequency bands to consider: • VHF (Very High Frequency) at 136-174 MHz • UHF (Ultra High Frequency) at 403-512 MHz • 800 / 900 MHz All bands have advantages for specific applications. As a rule, the higher the frequency, the better the in-building penetration. However, as you increase in frequency, you will decrease in range. VHF frequencies (136-174) are better suited for outdoor applications where maximum range is required with little to no obstructions. UHF and the 800 /900 MHz frequencies are better suited for indoor applications or environments with obstructions. VHF and UHF frequency bands are typically used for conventional two-way radios systems, while 800 / 900 MHz frequency bands are commonly used for trunking two-way radio systems. FEATURES A wide variety of features are available to help increase the efficiency, productivity and safety of your workforce. Efficiency/ productivity features include integrated data applications that increase a radio’s capability beyond voice communication, and telephone interconnect, which enables radios to talk with a telephone PBX system. Safety features include emergency notification for use during urgent situations and intrinsically safe certifications for hazardous work environments. TWO-WAY RADIO FEATURES INTRINSICALLY SAFE Intrinsically Safe is a designation that affirms a portable radio, with an attached certified battery, is safe for use in locations where flammable gas, vapors or combustible dust may be present according to the Division, Class and Group for which it has been approved. TELEPHONE INTERCONNECT Telephone Interconnect is a feature that enables a radio system to be connected to a telephone PBX system, which allows radios to make phone calls using the radio keypad. TECHNOLOGY Two-way radios have traditionally used analog technology. Digital technology is the next generation of two-way radio and offers several advantages over analog, including clearer audio, integrated data applications, 40% longer battery life and increased capacity. TEXT MESSAGING / GPS Using digital technology, Text Messaging communicates between radios, radios and dispatch systems, and radios to any email-capable device. Also using digital technology, GPS enables location tracking of vehicles and personnel in outdoor environments. THIRD PARTY DATA APPLICATIONS Third Party Data Applications expand the functionality of digital radios by enabling customized applications to be built for your unique business needs, including dispatch solutions, work order ticket management, system monitoring and much more. TRUNKING Trunking is a radio system configuration that uses a control channel to efficiently organize the radios and conversations on your radio system. This enables a large number of radio users to operate on the same system. EMERGENCY CALL Emergency Call allows a radio user, with the push of a button, to send a distress message to all other radio users to indicate an emergency and be given priority to talk.
