This document discusses 5 myths about small cell networks for indoor coverage. It summarizes the myths and provides the truths to debunk each myth in 1-2 sentences. The key points made are that WiFi is not always the best solution, dedicated indoor coverage through small cells is essential even with existing low-band spectrum, and small cells are better than DAS systems for driving data usage and new digital services. Overall indoor solutions through small cells are critical for mobile networks in the data era.
Huawei Chief Network Architect Wenshuan Dang: 5 myths of small cell
- 1. Wenshuan Dang Chief Network Architect Huawei Technologies Co.,Ltd 14 July 2015 5 Myths of Small Cell
- 2. 2 The Contradiction Indoor Outdoor Using MBB at¡ Investing MBB for¡
- 3. 3 Myth #1 WiFi is more effective for better user experience in public hotspot
- 4. 4 Truth #1 The Assumptions The Realities ?WiFi is faster and delivers better experience ?WiFi was faster than GPRS 15 years ago but much slower than 3G/4G most of time in most hotspot now ?Free WiFi hotspot offering can improve user satisfaction ?User perceive ¡°Free¡± as default instead of any premium value created by any operator ?WiFi is a cheaper solution to offload low value traffic ?No low value traffic at all, each byte is unique and important for every subscriber ?WiFi offload can enhance mobile network competitive edge ?4,000,000 wifi hotspots did not stop user churn out (a real case in china)
- 5. 5 Myth #2 I do not need dedicated indoor coverage implementation ¡because I have enough low band spectrum resource
- 6. 6 Truth #2 2,500,000 # of repeaters in use for GSM voice coverage today, and 70+% in 900MHz ¡dedicated Indoor coverage is essential
- 7. 7 Myth #3 Indoor coverage is important but its ROI (return on investment) is challenging
- 8. 8 Truth #3 ROI < 2 years 3.4x data zhengzhou china 6x data Singapore 3x data + 2x voice Indonesia ¡¡ A key platform for differentiated enterprise offering Indoor Locating, Indoor Navigation, Target Promotion, Footfall analysis, Employee checking¡.
- 9. 9 Myth #4 Indoor coverage is important but its too difficult to acquire indoor sites

- 11. 11 Myth #5 DAS (Distributed Antenna System) is more preferable for indoor coverage
- 12. 12 Truth #5 DAS is good for voice NOT for data xDynamic burst usage pattern xMIMO xHigher than 2.6GHz xLAA (license assisted Access) x256QAM xDigital service, LBS¡ ?Static stable usage pattern
- 13. 13 Summary ?No wifi offload, each byte is important ?Dedicated Indoor coverage is essential even if you have enough Low band spectrum resource ?Small cell is the pioneer to drive growth by stimulating ignored needs and boost digital service innovation ?Macro cell AND small sell, Not macro cell OR small sell ?Digitized indoor solution is essential of data era
