APPLICATIONS<br />

CT2's new features will lead to many new products not technically or commercially<br />

feasible using current CTl or cellular radio technologies. Table 1 shows new applications<br />

envisaged for CT2 in the four main operating environments: home, office, public places,<br />

and mobile.<br />

Note: T = technically not feasible; U s economically not feasible;<br />

CTl s first-generation analog cordless telephones, as used in the home<br />

today; CT2 s second-generation digital cordless telephones, to reach<br />

the market after mid-1989; DECT = third-generation DECT standards<br />

currently being developed by ETSI. Handsets are expected to reach<br />

the market after 1992.<br />

The first CT2 handsets (Shaye Communications' Forum and Ferranti's Zonephone)<br />

will go on sale in the United Kingdom this summer for use with the new telepoint<br />

services. These early handsets will use different and mutually incompatible standards,<br />

but will be superseded by handsets using the CAI standard after mid-1990.<br />
