McWiLL Network Architecture

Efficient Voice Package:       McWiLL is a data based system. The deployment of the data service is very simple. McWiLL specifies an efficient voice package to save spatial resources while keeping

high quality voice service, HEV (hear every voice). The inefficient connection is realized among the core system equipment via Ethernet, or fiber

 Topology P    Normal deployment

Topology M

Handoff:   

•      McWiLL technology adopts “Make before Break” (MBB) handoff to keep high mobile performance.

McWiLL spans the bridge of digital gap

QoS and GoS: 

•       Grade of Service (GoS):    Each terminal with its priority; Higher class terminals will have higher priority for bandwidth than the lower class terminals.

• Quality of Service (QoS):    Each service (voice, high priority data, and low priority data) queues in each link. Voice first then high priority data and finally low priority data; 

Combination of  the merits of CDMA and OFDMA

Xinwei Telecom Technology

It is based on CS-OFDMA adaptive modulation, and it uses dynamic channel allocation and smart antennas to enhance its throughput.

It all starts with a key• What is a key? • Encryption algorithm is like a recipe for

spaghetti. Key is like the choice of sauce that changes the end result.

Encrypt – Garble so it’s unreadable

Decrypt – Ungarble so it can be read again

Plain text

I am going to the market

encrypt algorithm – add x letters

key - 2 hard to read, UNLESS you

know the key
