M-Cell 6 comparison with Horizon macro
Comparison
overview
The Horizon macro is a replacement for M-Cell 2/6 base stations, and the
GSM/EGSM900 and DCS1800 Horizon
macro variants are directly compatible
with M-Cell
6 . For example, a mixture of up to four Horizon macro and M-Cell 6
BTSs can be combined to form a single site, with either a Horizon macro or an
M-Cell
6 being in control of the other units. Since many customers are familiar
with M-Cell
6 , and will use Horizon macro with M-Cell 6 , equivalent components
are described in this section, to assist understanding.
The Horizon
macro is a single cabinet, using reduced size and higher reliability
components. The plinth base fix points are the same as M-Cell
6 , though direct
replacement may require repositioning, to allow for adequate cabinet spacing.
The Horizon
macro can have a stacking bracket fitted to enable CCB installation,
and/or to enable mounting a second Horizon
macro .

and M-Cell 6
compatibility
A 24-carrier BTS site (in an 8/8/8 configuration) can be achieved by combining
four units as shown in Figure 1-5. This is the maximum BTS size. Each unit can
be either a Horizon
macro or an M-Cell 6 . Either a Horizon macro or an M-Cell 6
can control the other three units; the MCU of M-Cell 6 and the MCUF of
Horizon
macro being identical in control function.
An MCUF can be fitted into an M-Cell
6 and will then function as an MCU. An
MCU cannot be fitted into a Horizon
macro . Figure 1-5 shows a schematic
diagram of the digital connectons in a four cabinet BTS site.
