Introduction

1.1 Positioning To keep abreast of rapidly advancing mobile communications technologies, mobile operators are continually seeking partners who efficiently and cost-effectively provide cutting-edge technologies with which to build high-quality, multimode-enabled, and future-oriented mobile networks. Upholding the concept of continuous innovation based on customer requirements, Huawei has developed the future-oriented LampSite solution by integrating radio resources and multiple technologies. This solution is designed to expand system capacity, fill in coverage holes, and provide in-depth indoor coverage for multiple networking modes, such as GSM, UMTS, and LTE. The LampSite solution uses an optimized hardware and software architecture, featuring a simple architecture, easy deployment, low capital expenditure (CAPEX), and in-depth multi-mode coverage. In the LampSite solution, the base station comprises the baseband unit (BBU), pico remote radio unit (pRRU), and RRU HUB (RHUB). These modules can be flexibly combined to meet different scenario requirements.

1.2 Benefits Adopting a cutting-edge modular design, the LampSite solution is applicable to multiple networking modes and can use a few different modules to accommodate all of the different base station models. The solution is applicable to various installation scenarios, which significantly reduces the network construction costs and Operation Expenditure (OPEX) of operators during site acquisition, capacity expansion, and environment protection.

2.4 pRRU3901 Equipment The pRRU, a remote radio unit, processes RF signals as follows: 

The transmit channel receives the baseband signals from the BBU and performs digital-to-analog conversion. The baseband signals are up-converted to the transmit frequency band using the zero IF technology. The pRRU then filters and amplifies the signals, which are sent to the antenna for transmission.



The receive channel receives the RF signals from the antenna. Then, the RF signals are down-converted to baseband signals and sent to the BBU for processing after being filtered and amplified. NOTE

The CPRI data can be transmitted only using the Ethernet cable. pRRU3901 supports the following: 

Built-in or external antennas



PoE and AC/DC adapter



Flexible multi-mode configurations, with built-in RF daughter boards for multiple radio access technologies (RATs)



Wi-Fi daughter boards supporting data transmission services

2.4.1 pRRU3901 Exterior A pRRU can have two transmission ports or three transmission ports.
