The document introduces Signalwing's 5G distributed antenna system (DAS) and small cell solutions, including their 5G pRRU remote system, 5G active antenna solution, and 5G booster solution. The pRRU remote system extends the coverage of a single 5G pico RRU to an entire building using remote units. The active antenna solution replaces existing ceiling antennas with active antennas to provide 5G coverage without new wiring. The 5G booster solution adds a conversion booster to existing antennas to provide 5G service while keeping the existing infrastructure. Pilot tests showed the solutions met throughput standards.

11. 5G DAS
How to achieve the 5G indoor coverage effectively and economy is an challenge for all operators.
As to solve this challenge, we developed 3 series product:
1. 5G pRRU Remote System
2. 5G Active Antenna Solution
3. 5G Booster System
5G pRRU Remote System is focusing at solving the high cost ,hard and slow to construct in indoor 5G coverage.
As one 5G 4T4R pRRU can connect 8 items 2T2R RU, then it would be quicky in 5G construction. Meanwhile it can achieve 4T4R
split-level coverage, for example, 2nd floor 2T2R signal can cover 1st Floor, then 1st floor, mobile can achieve 4T4R effect.
This solution is to solve this problem-5G wiring. As 5G working is ultra frequency, but most of the IBS device only supports
below 2.7GHz frequency. Meanwhile 5g frequency loss is also high. Construct new wiring cost is also expensive and hard to
install. Adapt this solution, only replace this existed ceiling antenna with our active antenna, no install new wire. Then it can make
5G coverage effect.
5G booster system developed from 5G active antenna solution. This solution would not replace the existed 2G/3G/4G solution,
not even replace the ceiling antenna, only install a 5G booster in the target coverage area. Then it can achieve 2T2R 5g coverage
effect.

5G DAS- 5G pRRU Remote System
This systems is designed for 5G Pico RRU to
construct
5G indoor coverage.
As 5G pRRU is around 23dBm, it cannot achieve
large area coverage.
This system solve this problem.
It extends one 4T4R pRRU to 8 items 2T2R RU.
Use 1 pRRU can make 1 building coverage.

Explanations: 1F is covering with NR_1(conversion carrier) and NR_2 (direct carrier) , 2T2R. But the 2F is covering with NR_3 and NR_4, 2T2R.
2F NR_3 and NR_4 will also penetrate the floor and cover 1F. Therefore, it achieves the 4T4R coverage effect.

As over 2.7GHz, most of the cables and devices don’t be available, this is the reason to convert this frequency
to low frequency.
Then retore this frequency in 5G conversion booster. This solution don’t change the existed 4G wiring. And it
makes it quicky to construct reach 5G coverage. (the conversion frequency supports customize)

Since 2017, SignalWing started to enter in the small cell industry.
From cooperated and purchased BBU digital board to integrate with our RF board to introduce 4G integrate
small cell in the market and then self-developed 4G/5G distribute small cell based on open server X86 platform.
Our one BBU Support 4 5g
cells, each cell supports 128
active RRC,
384 connect RRC. Total one
BBU support 512 active
RRC,1536 connect RRC. One
BBU can maximum support 84
pRRU. Each 5g cell supports
2T2R channel, the max
download speed can reach
750Mbps. Meanwhile, this BBU
can integrate 4G board, each
4G board supports 4 cells, each
cells supports 2T2R.
