Antennas and cables are mounted on the extendable tower that can then be erected to full height, with or without guy wires. For cellular applications, a cell site on wheels (COW) can be rolled into key locations where an existing cell site is out of service to provide voice calling and Internet ac- cess to individuals and businesses alike. For first-responders, a mobile tower plat- form with a VHF/UHF base station can serve as a command center to coordinate police, fire, emergency medical services (EMS), and local military operations for Public Safety, and rescue and recovery operations. Having fully equipped mobile tower platforms that have been tested and are ready-to-roll will save precious time and resources during emergency and di- saster situations. The ability for two-way radios to "talk" to each other even though they operate on various VHF and UHF Public Safety fre- quency bands is critically important during wide-scale emergencies. To be effective, law enforcement agencies, firefighting companies, EMS, and other public health and safety departments must be able to communicate and coordinate with each other. Radio over IP (RoIP) systems enable radios among disparate Public Safety fre- quencies to communicate with each other efficiently and effectively in emergency situations over a common radio system. Developing an integrated radio plan allows first-responder companies and depart- ments in a given area to communicate with each other during critical situations. Communications Base stations provide a single point of ac- cess for multiple mobile devices. Base sta- tions operate on licensed and unlicensed frequency bands, depending on the ap- plication, whether in public or private net- works or for Public Safety communications. When permanently installed base stations are no longer functioning due to damage at the site or loss of site power, then mobile or portable base stations can temporar- ily restore wireless service in the affected areas. One of the more significant tech- nological advancements is the broadband wireless mesh network. Broadband wireless mesh networks have the added capability of enabling base stations on the network to communicate and link with each other to effectively transport multimedia (voice, Internet data, and video) signals. When any link in the mesh is broken, the network automatically reforms itself to redirect traf- fic over the remaining available, operating links. In this way, mesh networks maintain resilient, reliable communications. Communications PTP microwave radio systems are used to "haul" multimedia traffic from the edge or access part of the network "back" to the core of the network where the traffic can be switched and routed to the Internet, or to other wired or mobile devices. Wireless backhaul systems can operate over li- censed or unlicensed frequency bands, and can be configured for line-of-sight (LOS) or non-line-of-sight (NLOS) ap- plications, over short and long distances, and at throughput rates of up to 1 gigabit per second (Gbps). A wireless backhaul system operating from a mobile tower plat- form will ensure that emergency opera- tions in affected areas stay connected to network core switching sites and data cen- ters. Knowing the geography of the area and the available operating frequencies will help planning for the right PTP radios, antennas, and tower heights needed. Operations Public and private, and Public Safety networks cannot tolerate any downtime. Network core and data center operations include switching and routing functions and the handling of all data processing needs. These sites are supported with emergency backup power systems and redundant switching and routing equipment that are used to maintain critical communica- tions. High-speed backhaul connections in and out of the network core and data center can be over copper cable, fiber optic cable, or PTP microwave links. In the end, the survivability or restoration of a communications network in disaster situations is a function of the thought-out anticipation of disaster scenarios and a scru- pulously planned response for each. To help you prepare for and handle emer- gency situations and disasters, TESSCO maintains an inventory of critical communi- cations infrastructure equipment, including: licensed and unlicensed PMP, PTP and VHF/ UHF Public Safety radios; commercial and consumer two-way handsets and accessories; omnidirectional, directional, and parabolic antennas; copper and fiber cables; power systems and batteries; switches and routers; installation supplies; and mobile tower plat- forms. TESSCO also carries a wide variety of emergency supplies and equipment that can help individuals and businesses during ad- verse circumstances. To further assist you, we can assemble related, complementary prod- ucts into complete kits so that everything you would need is conveniently included in one kit, ready for immediate use.
