Broadband Internet network technology based Code Division Multiple Access (CDMA) Evolution Data Optimized (EVDO) Rev B has been present in the commercial for the first time in the world through Bali, Indonesia. The service is launched by the CDMA Wireless Service provider Smart Telecom which use Base Transceiver Station (BTS) from China’s ZTE and Qualcomm chipset technology from the United States.
Bali is known as a beautiful place of tourism in the whole world, and it can be central of focus telecommunication when that service launched.
What is the advantages of CDMA EVDO Rev B ? that question should be asked by someone who listens about the news.

In telecommunication world, the quality of voice service specified by two factors : GOS ( Grade of Service ) and QOS ( Quality of Service ). The Grade of Service can be measured using different sections of a network. When a call is routed from one end to another, it will pass through several exchanges. If the Grade of Service is calculated based on the number of calls rejected by the final circuit group, then the Grade of Service is determined by the final circuit group blocking criteria. If the Grade of Service is calculated based on the number of rejected calls between exchanges, then the Grade of Service is determined by the exchange-to-exchange blocking criteria
The Grade of Service should be calculated using both the access networks and the core networks as it is these networks that allow a user to complete an
end-to-end connection. Furthermore, the Grade of Service should be calculated from the average of the busy hour traffic intensities of the 30 busiest traffic days of the year. This will cater for most scenarios as the traffic intensity will seldom exceed the reference level

From New York times, A German enginner Karsten Nohl claimed that he’d already defeated by deciphering and showing weakness in GSM security which used in almost cellular system in worldwide in chaos Communication Congress. The Chiphering algorithm known as A5 claimed weak and no secure anymore.
As we know that GSM standard using A5 for privacy algorithm named Ciphering algorithm which has 64 bit binary code, but for now it is available for 128 bit binary code. The latest known as algorithm A5/3, and for 64bit binary code known as A5/1 which is claimed already weakness and should be replaced.
Maybe if you are not familiar with telecom term, you can analogy it with another one like Wireless technology Wi-Fi which has security standard like WEP ” Wired Equivalent Privacy“. But it has been changed to WPA (Wi-Fi Protected Access ) or WPA2.
