Statistics show 70% of 4G mobile services takes place indoors. Considering the diversified 5G mobile services and expanded mobile industry boundary, this figure will increase to 85%. Therefore, the quality indoor network will be the core competitive edge of mobile operators in the 5G era. As the network evolves from 4G to 5G, it will face multiple challenges in indoor mobile network, such as user experience, capacity expansion, network coverage, etc. 5G mobile network uses C-band and mmWave that are on much higher frequency than 2G, 3G, and 4G counterparts. Higher frequency bands lead to greater link losses. The signals on the even higher mmWave band will experience difficulty in penetrating through a wall as the link loss exceeds 60dB. Generally traditional RF cables and indoor network couplers do not support new frequency bands of 5G NRs (including the C-band and mmWave bands). Deploying new RF cables in indoor areas is costly and in a number of unique cases can prove impossible due to a lack of extra room for new cables. In addition, in traditional indoor distributed network, RF signals are carried over feeders, and each antenna needs dedicated feeders. This limitation requires multiple parallel RF feeders for multi-antenna solutions such as 5G 2T2R or 4T4R MIMO. If MIMO is used for extra expansion, new feeders must be routed, leading to a linear increase in engineering and deployment costs. And high-frequencies signals are subject to huge link loss when transmitted over traditional RF cables, which mean a much narrower coverage area and deteriorated performance. Therefore, it is difficult to use traditional indoor distributed network to increase network capacity. So, operators must use transmission cables that are easy to deploy and deliver high bandwidth. The best option is to use optical fiber to replace RF cables in order to meet the potentially huge bandwidth demand while ensuring superb 5G services. Utilizing ultra-wide bandwidth RF front-end design with Software Define Radio (SDR) architecture, Helios® Digital Multi-Band FTTA™ (Fiber to The Antenna) system enables the most flexible, scalable and complete carrier-grade solution for addressing small & medium coverage and capacity needs for Multi-Band 4G LTE and 5G NR together.

- First of all, This is our Multi-Band FTTA system, which is our innovative special design as a next-generation CPRI active DAS to solve small & medium indoor coverage. Our Digital Multi-Band FTTA™ is a three-tier architecture consisting of the Radio Access Unit (RAU), FTTA™ CPRI HUB Unit and Active Antenna Units (AAUs). let me introduce each components in details (next page)
- The outdoor roof-top RAU supports up to 3 * 2T2R RF paths and each RF path supports max 100MHz bandwidth and can be configured to be FDD or TDD mode in factory, which will very easily address a Single-Band or Dual-Band or even up to Tri-Band together. The outdoor roof-top RAU embedded 2T2R MIMO Donor Antenna already, so the end-customer just need to hang it up on the roof-top and align it to face to desired Donor BTS to get better cellular signal. By the way, with Power-over-Fiber (PoF) feature, it will be very simple installation due to there will be only one Hybrid Fiber-Copper cable to outdoor RAU, just like WiFi AP installation. Meanwhile, The RAU also have another option to support external N-type connector to connect the external high gain MIMO Donor Antenna in some special scenario. It generally accesses & synchronize outdoor 4G eNB & 5G gNB signals on air via embedded MIMO donor antenna, the signal is filtered, amplified and then converted to a digital CPRI data stream as well as synchronization signal (for 5G TDD). The digital CPRI packet data stream is transported via single mode fiber and received by the indoor remote Single-Band/Dual-Band/Tri-Band AAUs. It has two 10Gbps SFP+ digital optic ports and supports up to 7 indoor remote AAUs via indoor CPRI HUB by star network topologies for small & medium size coverage needs
- This is CPRI HUB, the FTTA™ CPRI HUB Unit is an indoor expansion element in our FTTA™ solution, it has total eight 10Gbps SFP+ optical ports to provide expandable connectivity up to seven indoor Distributed Active Antenna Units (AAUs) and one outdoor roof-top RAU over hybrid fiber-copper cable based on CPRI protocol by star topology /təˈpɑːlədʒi/ for small & medium coverage needs. It receives the CPRI data from RAU and transmits to the Distributed AAUs after shunting, the uplink CPRI data stream from AAU will be sent to the RAU after routing processing. It’s another important function is that provide innovative Power Over Fiber (PoF) features both for outdoor roof-top RAU and indoor remote Distributed AAUs to enable flexible & simplifies installation through hybrid fiber-copper cable.
- This is indoor AAU, the indoor remote AAUs then convert the digital CPRI packet data stream back to RF and control the switcher to DPD PA based on synchronization signal from RAU, then amplify the signal to the embedded 2T2R or 4T4R MIMO services antennas. On the reverse path (uplink), the AAUs and RAU perform the inverse functions and delivery the signals back to the corresponding outdoor 4G & 5G Base Stations. Our AAU can support single-band, dual-band and Tri-band with 2T2R, it is compact & fashion profile enables ceiling-mount, wall-mount and pole-mount. Meanwhile, The AAU also have Option with external N-type Connector to connect external High Gain MIMO Service Antenna in some high-rise floor scenario, like Entrance Hall in Airport or Railway Station etc.
- This is typical scenario for our Multi-band FTTA application. For small & medium [ˈmiːdiəm] in-building scenarios as smaller than 500sqm, such as underground packing lots, small office, factory, hotel or house building, small and medium-sized shops & stores, if the fiber backhaul is not available or the coverage & capacity requirement is small and it is not economic to directly deploy Base Station, and the outdoor LTE and 5G signal is good as min. RSRP -100dBm, and the indoor signal is not good due to big penetration loss by wall and windows, originally you would select traditional RF Repeater for such scenario, correct? Now, you can have better choice as Our Multi-Band FTTA solution! The outdoor roof-top RAU will get the outdoor LTE and 5G signal on air via embedded MIMO donor antenna, it will be very simplifies installation, just like install a WiFi AP, because the RAU is just need with one hybrid fiber-copper cable from indoor, and the end-customer just need hang it up on roof-top and align it to face to desired operator’s BTS to get better cellular signal, that is all. Then deploy the distributed AAU on indoor desired place via hybrid powered fiber cable from CPRI HUB Unit. Please note that the total system gain (from RAU side to AAU side) is Min. 85dB! This is incomparable /ɪnˈkɑːmprəbl/ with the traditional RF repeater + passive DAS solution, as you know, the traditional RF repeater generally is only 65~85dB gain design based on various /ˈveriəs/ RF power level and cost, but for such solution the final RF power level and gain arrived on each indoor service antenna after long way passive DAS transmission would be reduced 15~25dB loss, even more, and meanwhile it will also cause the uplink SINR is more worse. In addtion, it is also very expensive on hardware and installation cost if you want to implement 2T2R or 4T4R MIMO via parallel /ˈpærəlel/ two or 4 set of separate RF Repeater + Passive DAS. But, now it is very easy task to our Multi-band FTTA to help you to get a economic & reliable 2T2R high system gain and low noise level indoor DAS. Why FTTA is still economic, please carefully think about some key points about our FTTA: More higher system gain and lower uplink noise; Built-in 2T2R MIMO or even 4T4R also be implementable More lower installation cost, just like WiFi AP installation 4 AAUs sell pack can cover up to 30,000 sq.ft, it is equivalent /ɪˈkwɪvələnt/ to the capacity of +36dBm RF repeater at least, you can think about how much total cost of system design (such as very headache on RF link budget, Signal balance between MIMO, Uplink SINR control etc.) , installation and hardware of a set of Dual-band or Tri-band +36dBm or +40dBm Digital 2T2R MIMO RF repeater + 2T2R traditional passive DAS? (Important!) In addition, for operator there are still an advantage, if this site capacity requirement is increased and the fiber backhaul is available and operator would like to add a cell on there in future, they can directly add our BBU to connect the existing CPRI HUB, the existing CPRI FTTA DAS would become to 5G O-RAN DAS immediately.
- This is our recommended 4-AAUs pack sell with promotion discount, this pack include: Outdoor Roof-Top RAU, 1 unit FTTA Indoor CPRI HUB, 1 unit AAU, 4 units 1-pack 50meters outdoor hybrid fiber-copper cable, 1 roll 1-pack 200meters indoor hybrid fiber-copper cable, 1 roll 10Gbps SFP+ Transceiver, 10pcs For such sell pack, it can cover up to 30,000 Sq.ft. and get a economic & reliable Dual-Band or Tri-Band 2T2R high system gain and low noise level indoor DAS.
