In Conclusion

• Wireless Intelligent Networking allows the service provider to rapidly

introduce new services

• &obile PrePay is a common application

• %here are two overall standards employed today 6 $A&E- and WIN

• &aintaining and monitoring the $ommon $hannel "ignaling .$$"0

network is critical to its success

• !nderstanding and troubleshooting the ""7 protocol is a key part of

that success)
