CPA allows you to gain access to your Intranet or Internet service provider through "PacketWIN", a high-speed packet communication service provided by au. It offers optimum data transmission speeds of up to 2.4 Mbps[1] via au mobile phones. Since the communication rates are packet-based with uniform charges nationwide, you can use the service without caring about access points. The service areas are the same as those of the cdmaOne voice communication network, so it is possible to construct a high-speed, highly efficient mobile environment anywhere in Japan.

When CDMA 1X WIN- or CDMA2000 1x WIN-compatible models are used. |
The CPA network for PacketWIN access is constructed by connecting customer equipment to the KDDI access point using the KDDI network service.
The network rarely becomes busy because the lines are not exclusively used by users and line utilization rates are high.
Communications are done without using the lines exclusively, so for instance, even when you are on the move and lose the signals temporarily, communications resume immediately, and you don't have to manually reconnect to the network.
As it is charged based on the amount of transferred data (amount of packets) rather than the connection time, even if you are online, you will not be charged if there is no transfer of data.
By using "PacketWIN", a high-speed (best-effort type) packet service, attractive downstream speeds of up to 2.4 Mbps is available. Please note, however, that some CDMA 1X WIN models only offer maximum downstream speeds of up to 144 kbps.

Based on your requirements, it is possible to outsource RADIUS operations normally located within KDDI. The RADIUS server would receive the user ID and password sent from the access server and check user data to make a verification.
| * |
If you are unable to use RADIUS authentication from our end, you would be required to use it from your end.
|
The "KDDI Secure Contact" is a quarantine service that permits connection only to remote clients that meet its security standards. By not allowing contact with remote clients involving a high risk of virus or worm infection, it ensures construction of a safer remote access environment.
The RADIUS located within KDDI authenticates terminals based on their telephone numbers.
| * |
In order to use the terminal authentication service, customers are also required to sign up for the RADIUS authentication service.
|
Customers subscribed to KDDI's RADIUS authentication service can use the customer control service to register their user ID and password from home. The RADIUS account logs can also be viewed online.
IP addresses of the terminals can be assigned by selecting between two assignment methods: carrier assignment type (assigned by KDDI), and user assignment type (assigned by customers). In the user assignment type, terminal IP addresses can be fixed or dynamically assigned using customer's RADIUS, so it is effective when managing vehicle operations or using telemetering systems.
| * |
Charges apply in increments of 29 addresses. The first 29 addresses are free, but all subsequent addresses will be charged.
|
Access lines can be selected according to terminals connected and line speeds.
