Core Technologies: CS-OFDMA, Smart Antenna, Nulling, Dynamic Channel Allocation, Make-before-break Handoff.
Major Services: Fixed Phone, Mobile Phone, Mobile Voice, Data Transmission.
Major Products: Terminals (CPE, etc.), BTS (general macro BTS, etc.), Core Network (access aggregation and trunking soft switch systems, etc.), Application Platform (integrated message center).
Major Features: Exclusive Frequency Band (406.5 MHz-409 MHz, 1785 MHz-1805 MHz), Max Throughput of 15Mbps (5 MHz Frequency Band), Common Frequency Networking, Roaming, Voice and Data Handoff, TDD, Interface to NGN.
Simple Beamforming: McWiLL® smart antennas point the main lobe of beamforming towards the target terminal and point smaller side lobe of beamforming toward the external interference source to significantly reduce the interference level.
Spatial Nulling Beamforming: McWiLL® smart antennas point the main lobe of beamforming towards the target terminal and point a spatial null of beamforming at the external interference source to completely cancel the interference. Spatial nulling can cancel the interference with power 100 times as high as the signal power.
Spatial Nulling Technology
Supporting N=1 Deployment
Spatial Nulling Beamforming : McWiLL® smart antennas can also point the main lobe of receive and transmit beamforming at the target terminal in the cell and in the meantime point a spatial null of beamforming at the interfering terminal in the neighbor cell to cancel the co-channel interference and support N=1 deployment.
The Smart antenna system contains antenna array hardware and digital signal processing software. The antenna array comprises of multiple spatially separated antennas. The digital signal processing software processes the baseband signal sent by a target terminal and received by the antenna array and calculates its spatial signature and performs receive transmit beamforming toward the target terminal. Smart antenna beamforming can significantly increase the equivalent transmit power and receive sensitivity to greatly increase the communication coverage. For example, an 8-element smart antenna system can have 82=64 times more equivalent transmit power than a single antenna system. Since different terminals may be located in different places, the smart antenna system will perform different beamforming to different terminals, leading to significant reduction of interference among different terminals and increase of system capacity or data throughput.
Application of the projectCS-OFDMA integrates the merits of CDMA (more suitable for narrowband communications) and OFDMA (more suitable for broadband communications), making it an all-in-one communication system supporting both fixed and mobile voice and broadband data.
Dynamic Channel Assignment
The neighboring co-channel base stations use the interface detection scheme and dynamic channel assignment to coordinate channel assignment of multiple interfering terminals, leading to drastically reduction of co-channel interference among different cells and greatly increase the system capacity and reliability.
• The terminal maintains communication with both base stations during the handoff process.
• The terminal breaks the old link only after the new link is established reliably.
• The terminal performs handoff only after the layer 2 tunnel is established, making it possible for zero loss during the handoff.
• Layer 2 tunneling allows PDAs or laptops to keep the same IP address during the handoff.
• Layer 2 tunneling also allows the McWiLL® base station to interface with any standard routers without complicated mobile IP features.
