Time becomes a precious resource, and every second counts. The&nbsp;<strong>Radio Ambulance Project&nbsp;<\/strong>aimed to address this urgency by leveraging innovative technology to alert drivers and pave the way for quicker ambulance travel.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left has-black-color has-text-color has-link-color wp-elements-1b9e5872f0bd9e588b8debcd79b66062\" style=\"font-size:25px\"><strong>The Solution: LabVIEW and USRP Platform<\/strong><\/h2>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">The solution was born from collaboration between Maruri, an Ecuadorian advertising agency, and the Universidad Polit\u00e9cnica Salesiana. Using NI LabVIEW system design software, the NI LabVIEW Modulation Toolkit, and initially PXI systems, the team embarked on the Radio Ambulance Project. Their approach involved interfering with FM radio signals using the NI USRP (Universal Software Radio Peripheral) platform.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left has-black-color has-text-color has-link-color wp-elements-1d0d30f74c58f30c1e398cd00a2b1acf\" style=\"font-size:25px\"><strong>The Technical Journey From PXI to USRP<\/strong><\/h2>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">The initial phase utilized&nbsp;<strong><a href=\"https:\/\/www.apexwaves.com\/national-instruments\/pxi\">PXI<\/a><\/strong>&nbsp;systems, providing the flexibility, bandwidth, and power needed for wireless communication system development. However, recognizing the need for a more suitable platform, the team migrated to the&nbsp;<strong>NI USRP<\/strong>&nbsp;platform. This transition, surprisingly, required only a 15% modification of the source code, saving significant application development time.<\/p>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">The project involved a meticulous process of analyzing FM radio signals, demodulating them, generating an interfering signal, and broadcasting an audio message to alert drivers. The team conducted a successful proof of concept with an&nbsp;<strong><a href=\"https:\/\/www.apexwaves.com\/modular-systems\/national-instruments\/usrp-software-defined-radio-devices\/USRP-2920\">NI USRP-2920<\/a><\/strong>&nbsp;transceiver in June of 2013, utilizing an ambulance equipped with the system and a second vehicle to evaluate performance. The results were promising, showcasing the technical feasibility of the project.<\/p>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">Despite technical success, legal and regulatory hurdles emerged, restricting the open and widespread use of the system. The team addressed technical challenges by incorporating an RF amplifier, directional antenna, and a voltage inverter for power supply.<\/p>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">Maruri Grey estimated a 40% reduction in ambulance travel time, potentially increasing the chances of patient survival. While the technical feasibility was proven through the prototype, the next steps involved navigating legal and regulatory landscapes to implement the project on a larger scale.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/www.apexwaves.com\/blog\/wp-content\/uploads\/2023\/12\/pexels-pavel-danilyuk-6754163-1024x684.jpg\" alt=\"Paramedic getting an orange stretcher out of the back of an ambulance\" class=\"wp-image-2511\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-left has-black-color has-text-color has-link-color wp-elements-044a1879379137f11fa5de0c0a69114a\" style=\"font-size:25px\"><strong>APPLYING TECHNOLOGY FOR SOCIAL IMPACT<\/strong><\/h3>\n\n\n\n<p class=\"has-text-align-left has-text-align-left\">The <strong>Radio Ambulance Project <\/strong>exemplified the power of technology to address real-world challenges. By applying theoretical concepts of RF communications, the team demonstrated a practical solution to a major social problem.
