10 SECTION III RECOMMENDATIONS 3.1 HIGH DATA HATE RADIO LINKS It is recommended that law enforcement personnel throughout Anoka County continue to monitor progress toward implementation of high data rate radio communications links for use in mobile data communications. The monitoring should include gathering information in regard to pricing, data rate, reliability, and security of the data links. A decision should be made as soon as possible in regard to which of these high data rate radio communication links should be selected for long-term use. 3.2 MOBILE DATA COMMUNICATIONS It is recommended that all software that is developed and purchased for use with laptop computers in vehicles should consider future high data rate radio links and uses. It is also recommended that CDPD be implemented at the earliest possible date to keep the mobile data communication system from locking up during busier hours, especially during busier months. The CDPD technology utilizes TCP/IP communications protocol and, therefore, all software interfaces must utilize that protocol. Because the mobile data terminals do not have large display areas, in terms of the ability to display a large amount of text, and they do not have the capability to display graphics, it is recommended that those law enforcement agencies that use the MDT's migrate to use of laptops at the earliest possible time. 3.3 LINKAGE BE1WEEN THE COMPUTER-AIDED DISPATCH SYSTEM AND THE CDPD LAPTOPS The contractor for the computer-aided dispatch system, PSSI, has offered to implement a TCP/IP communications protocol linkage to the CDPD network for operation of laptop PC's in vehicles. This interface will include application software for the laptops that will permit them to function fully with the computer-aided dispatch system over the CDPD network.
