A base station is divided into two units as RRU ( remote radio unit) which is a RF processing unit and a baseband unit. RRU is connected to the BBU via optical fiber links. A BBU has a modular design , small size, low power consumption and it can be easily deployed.
A BBU comprises a digital signal processor to process forward voice signals for transmission to a mobile unit and reverse voice signals received from the mobile unit. The BBU acts as a centralized hub of the base station, it processes UL and Dl data traffic and controls the RRU functionality.
For macro stations, one BBU generates one logical base station (a base station consists of BBU, RRU, and antennas). One BBU connects to three RRUs (in general cases, excluding remote scenarios or situations in 3G where some macro stations correspond to four cells). One RRU corresponds to one antenna, and one antenna corresponds to one sector.
Baseband refers to the original frequency range of a transmission signal before it is modulated. A baseband unit is a unit that processes the baseband signals in telecommunication systems. A base station is divided into two units as RRU ( remote radio unit) which is a RF processing unit and a baseband unit.
In a distributed base station architecture, the traditional macro station equipment have two distinct units based on their functions: the BBU and the RRU. The BBU centralizes the “baseband,” “transmission,” “main control,” “clock,” and other functions of the base station.
For indoor distribution stations, one BBU can connect to three baseband processing boards. Currently, there are BBUs that can connect to six baseband processing boards). Each baseband processing board can connect to a maximum of six RRUs, and each RRU can connect to multiple antennas through couplers and power dividers.
The global solar storage container market is experiencing explosive growth, with demand increasing by over 200% in the past two years. Pre-fabricated containerized solutions now account for approximately 35% of all new utility-scale storage deployments worldwide. North America leads with 40% market share, driven by streamlined permitting processes and tax incentives that reduce total project costs by 15-25%. Europe follows closely with 32% market share, where standardized container designs have cut installation timelines by 60% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 45% CAGR, with China's manufacturing scale reducing container prices by 18% annually. Emerging markets in Africa and Latin America are adopting mobile container solutions for rapid electrification, with typical payback periods of 3-5 years. Major projects now deploy clusters of 20+ containers creating storage farms with 100+MWh capacity at costs below $280/kWh.
Technological advancements are dramatically improving solar storage container performance while reducing costs. Next-generation thermal management systems maintain optimal operating temperatures with 40% less energy consumption, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $80/kWh to $45/kWh since 2023. Smart integration features now allow multiple containers to operate as coordinated virtual power plants, increasing revenue potential by 25% through peak shaving and grid services. Safety innovations including multi-stage fire suppression and gas detection systems have reduced insurance premiums by 30% for container-based projects. New modular designs enable capacity expansion through simple container additions at just $210/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial projects typically achieving payback in 4-7 years depending on local electricity rates and incentive programs. Recent pricing trends show 20ft containers (1-2MWh) starting at $350,000 and 40ft containers (3-6MWh) from $650,000, with volume discounts available for large orders.
