Wireless access system

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 access.?

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 coverage.

The main technologies McWiLL adopts:

Smart Antenna:??????????????????? Directional emission by Phased Antenna Arrays with powerful algorithm

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

Digital city

Security dispatching net work (Police & defense)

Company communication (Airport, Oilfield, Power grid, Harbor, Construction, trasportation…)

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 deployment.?

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 other)

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)?????<200ms ?(faster than any other)

Group size ????????????????????????????????????????????????????????????????????????? No limit

Functions? ?????????????????????????????????????????????????????????????????????????? All functions of professional PTT

Cost efficiency

McWiLL boast lowest CAPEX and lowest OPEX.

The most cost efficient deployment is pure data service for internet access. US$140, 000 could start internet services. Voice and PPT functions are upon the data service with moderate extra investment of $30 -$120/line. A cost effective voice deployment allows 70$/line while possesses plenty of internet access capability.

Low BTS power consumption (250W/BTS) and optimized operation system keep operation and maintenance costs at low level. Once start, the system will definitely become a profit generator, no matter the operator is strong or not in marketing. ?
