For designers of communications equipment downtime is not an option. Both revenues and safety can be compromised under such circumstances. For example, cell enhancers and repeaters using bi-directional amplifiers for on-line signal repeating and boosting are widely deployed around the world for on-line signal repeating and boosting are widely deployed around the world for improving network coverage in buildings, tunnels, metros, stadiums and other areas of poor signal propagation. Problems with public mobile radio systems can be particularly serious in applications such as transport communications systems, particularly those used by the emergency services.</p> <div class="migration-injected-attachments"><div style="font-weight:bold;margin:15px 0 5px 0;">Attachments:</div><div></div><table style="border:0;"><tbody><tr><td width="160"><span class="_se_attachment" id="attid_https://www.element14.com/community/api/core/v3/attachments/1913"><a href="https://community.element14.com/cfs-file/__key/communityserver-wikis-components-files/00-00-00-01-00/Harsh-Environments.pdf">community.element14.com/.../Harsh-Environments.pdf</a></span></td><td><span style="font-size:80%;">Harsh Environments.pdf</span></td></tr></tbody></table></div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: sp:xp_power, design_guide, power_supply, outside, ac_dc, technical, harsh_environment, power</div>
