Public Dynamic – The default for CDMA equipment is a Public Dynamic IP address (which provides a different IP address for each data session and sessions can not be longer then 24 hours.). The default for HSPA equipment is a Dynamic Nat’d IP address, the key difference is that pool of primary IP’s is managed by a router and the equipment is protected by firewall, The router will work to obtain a public IP for internet travel but this avoids spam. This is also what causes problems for VPN connections and a tunnel cannot be created as access to the device is blocked by the router.
When devices are used as conduits (i.e. Modems for data loggers where the device attached is using the modem only for internet and wireless connection cards where the PC is using the card only for internet access)
Wireless Device – Internet – Client (or another user who finds the IP)
**Varies every session**
- No cost (except for data package required for connectivity)
- The risk of unwanted Internet traffic getting to your device is always there when using Public IP whether Dynamic or Static. The risk may be higher when using Static addressing because a hacker may keep attacking your Static IP address after he detects the presence of a device
Public Static – Allows direct interface with device from remote location via Internet
Wireless Device – Internet – Client (or another user who finds the IP)
- Cost is $10/month/user (SOC code = STIP)
- The risk of unwanted Internet traffic getting to your modem is always there when using Public IP whether Dynamic or Static. The risk may be higher when using Static addressing because a hacker may keep attacking your Static IP address after he detects the presence of a device. It is possible to remotely change the configuration of a Bluetree modem but the risk of a hacker actually doing it is very low.
- This application (Public Static IP) can be used when it is not mission critical/liable
- Mobility may not be able to provide a large number of Public Static IP addresses to a customer due to the growing global shortage of public IP addresses
- Would be used for SCADA applications such as switches or meter reading
Private Dynamic – Much like Public Dynamic provides varying IP addresses for each session but limits the use to the company only with a pipeline directly to the client.
Wireless Device – Pipeline – Client ONLY
- In situations for added security such as Police Services
- Costs less than Private Static (approx. $2500 less)
- An example is a wireless card or modem for connectivity in a Police car
- Private IP services are considered to be complex custom solutions. Private IP can only be obtained through the Complex Solutions team
- Tim Ing at Bell is the project lead (Solutions Architect)
Private Static – Provides a direct pipeline to the client with a specific known IP address for each modem.
Wireless Device – Pipeline – Client ONLY
- Client removes risk of unwanted internet traffic or hacking of a device
- Used in mission critical situations such as Railway switches, temperature monitor
- Private IP services are considered to be complex custom solutions. Private IP can only be obtained through the Complex Solutions team
- Cost of custom application can be $10K-$20K
- Monthly cost is at least TAC 1 at $5/month/subscriber (will vary depending on sol.)
Public Static or Dynamic IP
The key difference between Dynamic and Static (Dynamic changes, Static stays the same). If you wanted to use SCADA you would need a static IP.
Public Dynamic – when on HSPA Additional $5/month plus data plan
Static – Additional $10/month plus data plan
Private Static or Dynamic IP
The key difference between Dynamic and Static (Dynamic changes, Static stays the same). If you wanted to use SCADA you would need a static IP.
It’s important to note that your information is secure with a Private solution.
Dynamic – Custom development is involved and TAC support along with data plan
Static – Custom development is involved and TAC support along with data plan
How to access a Private IP device (Must be built with Dual WAN and the Server OS must support Dual WAN). A router that supports Dual WAN will work but hardware is generally better than software. Redundancy is normally required.
