Ericcson Interview Preparations, Ericcson baseband BB6630 & BB6631 commands for Ericsson baseband

The difference between Ericsson Baseband BB6630 and BB6631 is that the BB6630 is a single-mode baseband that supports only LTE, while the BB6631 is a multi-mode baseband that supports GSM, WCDMA, LTE, and 5G³⁴. The BB6631 is also more compact and energy-efficient than the BB6630².
Some of the main features of the BB6630 are:
Supports up to 12 LTE carriers
Supports up to 6000 connected users
Supports up to 3 cell carriers per sector
Supports 4x4 MIMO and 256 QAM
Supports Carrier Aggregation and Licensed Assisted Access
Supports Massive IoT with NB-IoT and Cat-M1
Supports up to 720W output power
Weighs about 40 kg
Some of the main features of the BB6631 are:
Supports up to 24 carriers across GSM, WCDMA, LTE, and 5G
Supports up to 9600 connected users
Supports up to 6 cell carriers per sector
Supports 8x8 MIMO and 1024 QAM
Supports Carrier Aggregation and Dynamic Spectrum Sharing
Supports Massive IoT with NB-IoT and Cat-M1
Supports up to 600W output power
Weighs about 25 kg
Moshell is a command-line interface tool that allows you to access and manage Ericsson base stations. Some of the basic commands for Ericsson baseband are:
lt all - load the full tree of managed objects (MOs) in the baseband
lpr - show the matching MOs or all MOs
momt - show the MO model tree
mom - show the MO model of a specific MO
momd - show the MO model details of a specific MO
al - show the alarms in the baseband
st - show the state of a specific MO
cvms - create a new configuration file for the baseband
invxrg - show the inventory of the baseband, including hardware and software versions
ping - test the connectivity between the baseband and another device
fui - show the device status of the baseband
nfigurationAllowed - enable or disable the configuration of the baseband
tionVersion - show the software version of the baseband
restart - restart the baseband or a specific MO
upgrade - upgrade the software of the baseband or a specific MO
Ericsson Radio Remote Unit (RRU) is a component of Ericsson Radio System that connects to a passive antenna and provides radio frequency signaling for one or several frequency bands¹. There are different types and models of Ericsson RRU, depending on the technology, band, power, and size requirements. Some examples are:
*RRU 4449*: A dual-band, high-power radio that supports 4x4 MIMO and 5G NR for bands 1/3/5/8/20/28/32/66/71². It has a compact design and passive cooling, and can be used for both macro and micro coverage³.
*RRU 2217*: A single-band, medium-power radio that supports 2x2 MIMO and 5G NR for band 7⁴. It has a slim and lightweight design and can be used for urban and rural coverage.
*RRU 4415*: A single-band, high-power radio that supports 4x4 MIMO and 5G NR for band 41. It has a robust and flexible design and can be used for capacity and coverage enhancement.
*RRU 4478*: A single-band, low-power radio that supports 2x2 MIMO and 5G NR for band 78. It has a small and discreet design and can be used for indoor and outdoor coverage.
The enclosure 6150 cabinet and the BTS 6102 are both site solutions for Ericsson Radio System, but they have some differences in their features and functions. Here are some of the main differences:
The enclosure 6150 cabinet is a multi-purpose site cabinet that can support various types of equipment, such as baseband, transport, and third-party vendors. It also provides a power system and battery backup. The BTS 6102 is a macro base station that is designed for outdoor use and delivers cost-effective coverage and capacity. It is used as a main-remote configuration with remote radio units (RRUs)¹².
The enclosure 6150 cabinet has a climate system that keeps the cabinet temperature within specified limits. It can be installed in different environments, such as rooftops, walls, or poles. The BTS 6102 has a weather-tight cabinet and integrated cooling system that protect the electronics and reduce power consumption. It can be installed on the ground level or on rooftops¹².
The enclosure 6150 cabinet can support up to 20 kW of heat dissipation and up to 16 RUs of equipment space. It can also support up to 16 battery strings for backup power. The BTS 6102 can support up to 2x40W or 4x40W of transmitter power output and up to 4 RUs of equipment space. It can also support up to 4 battery strings for backup power¹³.
I hope this helps you understand the difference between the enclosure 6150 cabinet and the BTS 6102
