Traffic is always booming in the hotspot locations, such as CBD, office building, Stadium, etc. User experience is vital for mobile operators, as most users there are high-value subscribers and their contribution to operators 'revenue is important.Mobile operators are usually paying much attention to urban areas’ networking, but they still came into some challenges during building and operating network:
● High burst rate of real-time services, such as online video, VR/AR
● Difficulty on site acquisition, considering
● High entry fee when installing indoor base station
● If there is no fiber, then backhaul will be a problem, as it can hardly allow fiber deployment projection
Baicells Small Cell is integrated product, with Antenna, Radio Unit and BBU all in one box, supporting multi-band, multi-mode (LTE FDD/TDD + WiFi), and multi-RAT (GSM+LTE) for voice & data traffic, suitable for the hot-spot, including indoor and outdoor scenarios to increase the LTE network coverage and capacity.
Specific scenarios and corresponding solutions
For multi deployment of small cell in one area, there might be interference challenge which will limit the network performance. Here, Baicells offers the innovative Flex-RAN solution to customers to reduce the complex of network planning and deployment, and use joint-scheduling to improve the network capacity.
CU: Center Unit, including L2 /L3, joint scheduling, cell merging.
DU: Distributed Unit, including PHY and RF.
DU (Small cell)
For the case where one carrier can not meet the capacity requirements, Baicells provides multi-band Neutral Cell, which could integrate three LTE cells into one box, together with WiFi. Besides, NeutralCell enables new business model: Multiple operators sharing one site. Neutral host service providers could rent the same eNB to other telecom operators, which avoids repeating construction and creates the added revenue for telecom operators.
Multi-band Neutral Cell, supporting LTE + Wi-Fi
For outdoor scenario, Baicells could also provide the products of Dual Carrier, with inter-band Carrier Aggregation (CA) capability.
For the customer with limited spectrum resource, LAA (Licensed Assisted Access) is the optimum choice to improve the network capacity. Baicells’ CBRS eNB can utilize the 3.5GHz to be the supplementary data links while a licensed band is used as the “anchor” carrier.
Another challenge for small cell is the backhaul requirements, Baicells provides innovative CrowdCell for UE relay, which is:
● All in one box (eNB + UE)
● Plug and play
● Backhaul through LTE, reduce almost 90% of the backhaul CAPEX
● Increase the spectrum efficiency
