McWiLL is the most advanced broadband radio solution provided by Beijing Xinwei Telecommunications Technology. The engineering is based on SCDMA, and is known as Multicarrier Wireless information Local Loop ( McWiLL ) . McWiLL combines SCDMA ‘s traditional usage in narrow-band voice and introduces a nomadic broadband informations service that ties into an IP-based nucleus web. It is based on CS-OFDMA adaptative transition, and uses dynamic channel allotment and smart aerials to heighten its throughput.
SCDMA is a wireless entree engineering developed by Beijing Xinwei
Telecom Technology Co. , Ltd. The SCDMA air interface is a national radio entree criterion in China. The SCDMA merchandises contains a full suite of advanced radio
communicating and networking engineerings, such as smart aerial. The cardinal engineerings of SCDMA form the foundation of TD-SCDMA, an ITU Standard for 3G Wireless Communications. Earlier SCDMA merchandises are narrowband merchandises concentrating on fixed and nomadic voice applications. A new coevals of SCDMA merchandises are broadband merchandises, Multicarrier Wireless Internet Local Loop ( McWiLL ) , concentrating on fixed and nomadic voice and high velocity informations application.
McWiLL has been deployed in several Chinese metropoliss, including Guangzhou and Qingdao, where it ‘s been used for picture, voice and informations communicating. McWiLL successfully served for 2008 Beijing Olympic Regatta, supplying the high-definition, real-time Mobile picture services. Internationally it has been deployed in more than 15 states, such as USA, Cameroon, Nigeria, Ukraine, Malawi, and Mozambique.
McWiLL is a TDD-based radio entree platform that combines SCDMA ( synchronal CDMA ) , CS-OFDM ( codification distributing extraneous frequence division multiple entree ) , MIMO and smart aerial, every bit good as other radio techniques such as adaptative transition ( up to QAM64 ) , dynamic channel allotment and make-before-break handoff, to offer a high-velocity information and voice services. All these characteristics are designed to work with any IP nucleus web and supply up to 15Mbps of informations rate utilizing 5MHz of spectrum.

In a manner, McWiLL tries to integrate all of today ‘s radio networking techniques into a individual platform which is really perchance why it is about impossible for a normal human to understand.
McWiLL Base Station supports the undermentioned characteristics:
( a ) Support up to 15Mbps cyberspace throughput with 5MHz bandwidth ;
( B ) Support fixed and nomadic, voice and informations services ;
( degree Celsius ) Support up to 163dB nexus budget ;
( vitamin D ) Support Make-before-Break handoff and L2 tunnel ;
( vitamin E ) Support QoS and GoS characteristics ;
( degree Fahrenheit ) Support Over-the-Air ascent ;
( g ) Support low power ingestion ( 150 Watt ) ;
( vitamin E ) Support VLAN, PPPoE and incursion of private webs

McWiLL System Features
Main Servicesi?sFixed, portable, nomadic voice and informations communications.
Main Featuresi?sBTS with 5MHz can back up up to 15Mbps cyberspace throughput, each sector can back up more than 300 coincident Sessionss, back uping high-velocity mobility, handoff and roaming, N=1 frequence planning, and low latency.
Support up to 100KM/H Mobiles velocity
Terminals are rearward compatible
Support efficient voice communications and low-bandwidth informations.
Support N=1×1 deployment.
Merchandises available in the undermentioned frequences:
336-344MHz, 400-430MHz, 698-746MHz,1785MHz-1805MHz, 2150-2180MHz, 2525-2560MHz, 3300-3400MHz
Features of Chinese Rural Areas
Low endorser denseness, big separation of small towns, far off from urban countries
Complicated environment ( cragged and hilly terrain )
Poor installation ( backhaul, power supply, etc. )
Current wireline/wireless communicating systems can non run into these challenges
Less than $ 4/month in most countries
High traffic particularly in Chinese traditional vacations
More incoming calls than surpassing calls
Small use of value added services
Unique Advantages of Deploying McWiLL
Large coverage enables fewer cell sites which are expensive in developing states, taking to much lower Capex and Opex. N=1 deployment enables a broad country web with every bit small as 5MHz spectrum, taking to much lower upfront investing on spectrum which is normally rather expensive. Merchandises with a broad scope of frequence allow an operator to take the most cost effectual spectrum to run. Lower terminus cost and equal informations rates allow an operator to minimise the Opex and lower the entry barriers for a endorser. Most McWiLL terminuss can back up both voice and information services. GSM/McWiLL double manner handsets/PDAs allow an terminal user to bask 3G beyond public presentation of McWiLL informations and cost effectual voice without giving easy entree advantages of GSM.
Summary of McWiLL Advantages
Large coverage ( up to 60Km )
Smart antenna,400MHz frequence set

In this presentation, we will foremost give an debut of popular
radio manifold engineerings such as WCDMA and OFDMA and so show
our McWiLL engineering which is an optimum integrating of WCDMA and OFDMA
engineerings to efficaciously turn to the proficient challenges of radio
broadband entree, such as capacity, coverage, multipath attenuation, and
intercell intervention. In other words, McWiLL efficaciously avoids the
major drawbacks of WCDMA and OFDMA and pull their advantages of both
engineerings. Unlike voice centric WCDMA or informations centric OFDMA ( WiMax ) ,
the McWiLL radio broadband entree system can expeditiously unite
both voice and information applications. Finally, we will supply brief
debut of McWiLL merchandise roadmap and application.

Multicarrier Wireless Internet Local Loop ( McWill ) is developed by Beijing Xinwei Telecom Technology Co. , Ltd. It is a wireless entree engineering which can cover for the really big country, its coverage can up to 60KM. Therefore it is really suited for China because it is a large state. It ‘s been used for picture, voice and informations communicating and successfully served for 2008 Beijing Olympic. Even though McWill is really popular but it can non be usage for every state for illustration, Singapore. Singapore is a little state if utilizing the engineering of McWill, there will be a batch of wasted.
