HIGH EFFICIENCY 48V OUTDOOR POWER MODULE FOR 5G MICRO BASE STATIONS
What are the 5G outdoor base stations
Due to the high propagation loss and blockage-sensitive characteristics of millimeter waves (mmWaves), constructing fifth-generation (5G) cellular networks involves deploying ultra-dense base stations (B. [pdf]FAQS about What are the 5G outdoor base stations
What is a 5G small cell base station?
5G Small Cell indoor and outdoor 'all-in-one' radio access for private 5G wireless networks. 5G Small Cell Base Stations (Micro Cell, Femtocell) offer advanced features and “stand alone” capability for private networks.
Can a 5G base station be installed outside?
The Baseband is available in 1U standard and 3U enhanced versions for indoor 19″ rack mount deployments. Can be mounted in outdoor housing/enclosures Optional Full-Outdoor versions are available. A complete range of Remote Radio Units (RRU) are available for 5G-NR 5G Base Station applications in Frequency Range 1 (sub-6GHz) bands.
What are 5G NR and 5G base stations?
Frequency bands for 5G NR and 5G Base Stations are being separated into two different frequency ranges: Frequency Range 1 (FR1) includes sub-6GHz frequency bands, some of which are bands traditionally used by previous standards, but has been extended to cover potential new spectrum offerings from 410 MHz to 7125 MHz.
What is x4000 5G SDR small cell outdoor base station?
X4000 5G SDR Small Cell Outdoor base stations enjoy great flexibility, high performance as well as very low cost of operation and ownership. "Stand Alone" operation is possible which enables the 5G Base station to connect remote terminals without need for external network elements.
Should 5G base stations be tripled?
To cover the same area as traditional cellular networks (2G, 3G, and 4G), the number of 5G base stations (BSs) could be tripled (Wang et al., 2014). Furthermore, Ge, Tu, Mao, Wang, and Han, (2016) suggested that to achieve seamless coverage services, the density of 5G BSs would reach 40-50 BSs/km 2.
What is a x4000 5G base station?
"Stand Alone" operation is possible which enables the 5G Base station to connect remote terminals without need for external network elements. Custom designed for private 5G mobile networks using 5G FR1 radio spectrum. The X4000 5G 'All-in-One' includes Radio Unit (RU), Distributed Unit (DU) and Centralised Unit (CU).
Why do base stations all use 48V power
Products basically use -48V power supply system, and the actual measured voltage is generally –53.5V. This is because for reliability reasons, communication equipment is equipped with a backup battery (-48V). [pdf]FAQS about Why do base stations all use 48V power
Why do we use 48V power supply?
The choice of 48V was to maximize the distance between the user and the end office under the conditions at the time (36V is a safe voltage, and it is unsafe to exceed too much). Later, in order to be compatible with early equipment and reduce costs, the central office communication equipment still used -48V power supply.
Can a 48 volt DC power supply save a data center?
(Fig. 5) As shown in this example, when the power per rack exceeds 10 kW, the power distribution loss generated by traditional 12-V DC power is said to reach an intolerable level, but a 48-V DC power supply significantly contributes to power saving for a data center.
Why is 48 a good system voltage?
Back in the day, when Telephony equipment was being developed, 48 was the chosen system voltage because it’s considered safe “low voltage”, and reduced amperage requirement of equipment powered at this voltage.
What is the operating voltage range for -48V system equipment?
For -48V system equipment, the required operating voltage range is -38.4V ~ 57.6V, but in fact we generally require the operating range -36V ~ -72V. The main consideration is that -48V system equipment must be compatible with –60V power supply system, which requires –48~-72V.
Can a 48-V DC converter be used with a 12-V DC power supply?
When a 48-V DC power feeding is adopted, the power configuration of the DC/DC converter needs to be changed from the 12-V DC power supply. Briefly described, two methods are used. The single-stage method reduces the 48-V power source to the load voltage by using a single power supply.
Why did Bell choose -48VDC?
In the late 1800’s, most homes of were not yet wired for electricity; in fact, communications beat power to the home in much of the United States. The reason Bell selected -48VDC is because it provides enough in power to support a signal, but not enough to be dangerous.
