CTA provides high quality professional consulting services spanning the entire USA, with the strength and support of HSMM, a major A/E firm.  The communications projects undertaken by CTAfrequently require both communications expertise and structural, mechanical, or electrical expertise associated with A/E construction service providers.  The A/E construction capabilities of HSMM complement the communications capabilities of CTA Communications.  In addition to two-way radio applications, we provide in-house services for the programming, planning and design of emergency communications and operations centers.  We are experienced in the technical areas of 9-1-1 customer premise equipment, computer assisted dispatch systems, dispatch furniture and other ergonomic issues.  Our experience with administrative and operations planning, particularly public safety operations planning, has emphasized that many communications problems do not have exclusively technical solutions, but also require a knowledge of and sensitivity to the operational situation.
