300MHz To 3.5GHz Frequency Samrt Atennas 4G Wireless Technology
Samrt atennas
McWiLL smart antennas is based on 8 phased antenna array technology with high efficient algorithm. The 8 antenna arrays realize “beamforming”to and from each terminal The energy concentrates largely in direction to different terminal, or actually point to point, from antenna array to terminal. Beamforming provides a gain+20 to +30 dB.
Nulling
The BTS could find the interference source and send a null singnal offset the interferncefrom the interfernce from the source. Nulling provide a gain of 18dB.
Frequency Range: 300MHz to 3.5GHz
Frequency with ready system: 336-344MHz, 400-430MHz, 698-746MHz, 1785-1805MHz, 2150-2180MHz, 2520-2560MHz and 3.3-3.4GHz. Possible for developing on other bands.
Frequency of integer MHz: 1 MHz, 2MHz, 3MHz, 4MHz, 5MHz; By 5 MHz, the capacity utilization of single BTS is highest.
Frequency efficiency and reusability
Frequency efficiency: 4.8b/s/Hz raw; 3b/s/Hz net; BTS throughput: 15Mbps /5MHz;
McWiLL shows its high SNIR (low probability of insufficient SINR) in most covered area to reach 64QAM. The capacity claimed by McWiLL is, therefore, much closer to the reality than any other technology.
McWill is great at Common Frequency Net Working (Co-frequency, or N=1 networking). When co-frequency, the capacity loss in overall coverage is less than 15%. In the network of N=2 and N=3, the capacity loss is minimized.
