Detail: Wireless access system-commercialized 4G technology
McWiLL is the only commercialized 4G technology in the world. The
technology is based on SCDMA developed by Beijing Xinwei. The
latest International standard ITU-R M.1801-11 published in April
2010 lists McWiLL, in the name of SCDMA, in Annex 7 for wireless
McWiLL is characterized with:
Multimedia Service: Telephone, Internet access, PTT and Video
Surveillance, all in one system.
High Throughput: 15 Mbps at 5MHz; 120 concurrent voices; 20
concurrent PTT groups;
High Quality Coverage: Up to 70 km, NLOS, in rural; Good
penetration in city;
High throughput broadband service realized in most places under
The main technologies McWiLL adopts:
Smart Antenna: Directional emission by Phased Antenna Arrays with
Interference Nulling: Depress noise by sending an offset signal.
OS-OPDMA: Combination of advantages of WCDMA and OFDM technology
Efficient Voice Package: HEV voice by special package of voices
with limited band occupation
McWiLL support long distance most applications at low costs:
Newly established public network;
Rural Telecommunication Service
Security dispatching net work ( Police & defense)
Company communication ( Airport, Oilfield, Power grid, Harbor,
Internet Service Providing ( ISP)
McWiLL are characterized in wide a service range. Voice and data
services are integrated in one system. The voice service of McWiLL
is better 2G and Data service is better than existing 3G. It is not
necessary any more to set up two systems separately for voice and
data. MBB handover supports mobility of 120km/ h.
Mixture of Voice and Data
One BTS covers area up to radius 70KM in rural and 1-3 km in urban.
In a good coverage area with 5 MHz bandwidth, one BTS supports data
communication 15Mbps, up and down. In the area of extremely high
density usage, a cell could be covered by three BTS, 45Mbps.
Under TDD mode, the up/ downlink ratio is adjustable as 1/ 7, 2/ 6,
3/ 5, 4/ 4, 5/ 3, 6/ 2 and 7/ 1, suitable for the applications from
purely internet download to purely video surveillance.
Typical combination: 50 voices + 16x512Kbps;
Voice intensive: 120 voice + 12x512Kbps;
Pure data: 24X512 kbps;
PTT focus: 20 PTT + 40 other voices+ 12x512kbps
Pure video 24 video cameras;
Strong Trunk Radio( Trunking Radio, PTT, command dispatch) :
McWiLL PTT shows superior trunking performance with low costs of
The uniquely powerful mobile video surveillance and data dispatch
capacity provide security users with plenty of new possibilities
for the mission implementation.
McWill provide with low cost PTT solution for both industrial users
and public net work.
120km/ hmobility supports helicopter surveillance.
Max. PTT under one BTS 20 groups concurrently ( much more than any
Large net work roaming support ( inter-city or cross country)
PTT Call Set-up Delay ( Ready to Speak) < 500ms ( at least as
fast as any other)
PTT Occupation Delay ( Start to Speak, PTT Set Up)
