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

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
