DZMx firmware platform 4
(v4.x.x) is on-track to be implemented before the end of Q2 2020. This
firmware platform supports a new CPU that will be capable of supporting the data
requirements of the DZMx for many years to come. In addition to this, the
current cellular modems have been discontinued by the component supplier and
this firmware platform will support the introduction of replacement modems.
The CPU change will be transparent
to customers and it does not affect compatibility with previous DZMx versions,
however the cellular modem change does have some implications for new purchasers.
The new modems cannot operate globally at 4G/LTE data rates and they will need
to be ordered for the geographical region the DZMx will be operating in. However, they will still work outside of their allocated regions at a
fallback 3G data rate. The new modems are VoLTE ready and most have improved frequency
band support for the regions they operate in, e.g. 700MHz for Asia Pacific, North
America and Latin America.
The DZMx dash numbers will
change to reflect the new modem options and a list of the new numbers will be
sent to partners and resellers, prior to the firmware release.
