  We present the first detailed radio study of the galaxy cluster XMMXCS
J2215.9-1738 at $z$ = 1.46 using MeerKAT $L$-band (1.3 GHz) observations. We
combine our radio observation with archival optical and infrared data to
investigate the star formation and AGN population within $R_{200}$ ($R = $ 0.8
Mpc) of the cluster centre. Using three selection criteria; the radio
luminosity, the far-infrared radio ratio ($q_{\rm{IR}}$) and the mid-infrared
colour, we distinguish galaxies with radio emission predominantly powered by
star formation from that powered by AGNs. We selected 24 cluster members within
$R_{\rm{200}}$ in the MeerKAT image based on either their photometric or
spectroscopic redshift. We classified 12/24 ($50\%$) as galaxies whose radio
emission is dominated by star-formation activity, 6/24 ($25\%$) as intermediate
star-forming galaxies and 6/24 ($25\%$) as AGN-dominated galaxies. Using the
radio continuum luminosities of the star-forming cluster galaxies, we estimated
an integrated star formation rate (SFR) value of 1700 $\pm$ 330
M$_{\odot}$yr$^{-1}$ within $R_{200}$. We derived a mass-normalized integrated
SFR value of $(570 \pm 110) \times 10^{-14}$ yr$^{-1}$. This supports previous
observational and theoretical studies that indicated a rapid increase in star
formation activity within the core of high-redshift clusters. We also show that
the high AGN fraction within the cluster core is consistent with previous
cluster observations at $z >$ 1.5.
