This solution uses Femtocell technology to solve indoor signal blind spots and hotspot area expansion problems. TD-LTE Nanocell and its end-to-end system solutions make full use of WLAN access points and transmission resources, and use existing standard broadband connections as a low-cost network backhaul, which can effectively reduce network deployment and operation costs.
TD-LTE Nanocell (Femtocell + WLAN) is another new technology that has been gradually developed in the field of telecommunications infrastructure. This technology helps large-scale TD-LTE network construction. Insufficient coverage of indoor signals and difficulty in expanding hotspots are two important issues facing TD-LTE network construction. TD-LTE Nanocell technology can help solve these core problems.
Femtocell technology provides low-cost network access for indoor and hotspots, and is destined to become a new bright spot in the mobile communications industry. It is believed that Nanocell (Femtocell+WLAN), which combines the power of cellular technology and WLAN technology, will not only become a weapon for large-scale TD-LTE network construction, but also open up new development directions for the development and evolution of next-generation 5G (WLAN). .

Support RF Transceiver Gain Automatic Control (AGC)
High integration, low power consumption
This solution has the following characteristics:
1. Simple structure and low cost. The wireless access solution is based on Intel's SoC chip architecture. The baseband processing uses an integrated SoC chip, and the RF small signal processing uses an ADI RF agile transceiver to achieve low cost, small size and low power consumption.
2. With coordinated and integrated access capability, customers can support cellular network and WLAN access based on this solution, and realize the integration of small base stations (Femtocells) and WLAN APs. The design reduces the interference of the two wireless access modes systematically and shares the backhaul of the two accesses.
3. Use a flexible, low-cost backhaul network. The solution is connected to the network through an IP interface, and its backhaul network is more flexible. It can use wired and wireless methods as a backhaul network. Its fixed broadband network can use the carrier's own broadband backhaul network or a third party with a cooperation agreement. The network implements the return of data.
4. Achieve a converged core network. Initially implement carrier-class cellular and WLAN authentication, access and network management. Subsequent evolution to the convergence of cellular and WLAN networks, through the integration of 3GPP and WLAN technical standards to achieve simpler and more efficient data transmission and management.
