Proxicast - Many 3G (third generation – EVDO / HDSPA / HSPUPA / UMTS) cellular carriers have begun to enforce limits on their previously “unlimited” fixed-price cellular data plans. Some wireless carriers now only offer cellular data plans with a maximum data allotment of 5 GB or less per month. These new pricing plans are having a chilling effect on businesses that were planning or have already deployed cellular data applications. They fear receiving out-of-control cellular bills with exorbitant overage charges because they have no easy way to monitor cellular usage or reign in users and applications.
For example, downloading large files using a high-speed 3G cellular data service such as EVDO RevA, HSDPA or HSUPA can easily consume 300+ MB per hour – exhausting an entire monthly 5 GB allotment in just 16 hours. With some carriers charging 50 cents per megabyte over the cap, each extra gigabyte used could cost the user an additional $500.00
Cell-Sentry™ is Proxicast’s exclusive new LAN-Cell 2 firmware feature developed in response to this change in cellular data plan pricing and based on feedback existing LAN-Cell cellular router customers. Cell-Sentry is a watchdog application built into the LAN-Cell 2 3G router that monitors cellular usage and alerts administrators via e-mail when a user-defined threshold is reached. It can even block additional cellular usage via hard "not to exceed" limits to avoid overage charges. Cell-Sentry can monitor data or time usage to match the carrier’s billing policies.
Cell-Sentry’s usage budget is linked to the wireless 3G modem card; modem cards can be swapped in and out while maintaining the budget’s integrity. The budget data is also preserved across system restarts and power cycles. And the budget can be auto reset on a user-specified schedule to coincide with the carrier’s billing cycle.
Even if the user does not anticipate going over their wireless plan’s monthly allotment, the unique Cell-Sentry feature can protect against "run-away" applications that might utilize excessive amounts of bandwidth or from unplanned users connecting to the device and transferring large amounts of data.
Proxicast’s LAN-Cell 2 cellular routers also include several other features that help control cellular data costs. Bandwidth Management – The flow of data to the 3G cellular modem can be “throttled”, restricting the maximum speed to less than the available capacity from the carrier. For example, many video surveillance applications may only require 100-300 Kbps, but the user has no easy way to slow down the camera’s data rate. With bandwidth management, the user can adjust the maximum outbound data rate to stay under their plan’s limits.
• Dial-On-Demand – The ability to make instantaneous 3G connections only when outbound packets need to be routed to the Internet and automatically drop the connection when it is idle.
• Firewall Rules – Using stateful packet inspection technology, administrators can block bandwidth hogging applications such as audio streaming or video conferencing.
• Keep-Alive Timers – The amount of data used to maintain a cellular connection can be adjusted and the LAN-Cell can restart at specific times and stay connected only for a fixed duration.
• Security Features – Unauthorized users can be prevented from accessing the Internet. Unsolicited traffic from hackers can be reduced via anti-probing features and secure user-definable management interfaces.
These data management tools can result in significant savings for users who need to transfer a fixed amount of data on a regular basis by allowing them to confidently take advantage of cellular carriers’ less expensive metered data (telemetry) plans. These plans often start as low as $5.00 per month compared to $60.00 to $80.00 for typical multi-gigabyte plans.
Proxicast has prepared an in-depth Tech Note on how to use Cell-Sentry and other LAN-Cell 2 features to manage cellular data costs. The Tech Note is available for download on Proxicast's web site.
