What Is Mobile Broadband Internet Access Service?
Mobile Broadband Internet Access Service refers to any of our data services that a customer may use with a Smartphone, aircard modem, tablet, or other wireless device that are appropriately configured to work on our network for connection to the Internet utilizing either the 4G LTE or 3G EVDO network. It provides the capability to transmit data to and receive data from all or substantially all Internet endpoints, including any capabilities that are incidental to and enable the operation of the service. Mobile Broadband Internet Access Service does not include services that use the Internet for connectivity but which only provide access to limited Internet endpoints such as is common with many M2M services.
What Are U.S. Cellular's Mobile Broadband Network Management Practices?
U.S. Cellular employs reasonable network management practices that are appropriate and tailored to achieving a legitimate network management purpose. Legitimate network management purposes typically include reasonable security practices by providing: confidentiality, integrity and availability of network services, reasonable measures to address traffic that is harmful to the network and providing services or capabilities consistent with customer's choices regarding services offered.
U.S. Cellular only optimizes HTTP traffic. HTTP traffic consists of both watching video and Internet browsing. U.S. Cellular uses optimization methodologies described below:
Video Optimization (3G EVDO only)
Two types of optimization techniques are utilized by U.S. Cellular for video, Lossless Video Optimization and Lossy Video Optimization:
Lossless Video Optimization
Lossless Video Optimization reduces the amount of video traffic without changing the quality of the contentâ€“using the Just-in-Time technique. Such technique manages the download of video over the network to match the rate at which it is being watched by the customer. This improves capacity utilization and performance by minimizing wasted traffic caused by video downloads to a buffer, which are terminated before viewing completion.
Lossy Video Optimization
Lossy Video Optimization removes inefficiencies in the encoding of video and optimizes the video to better suit the network and the device. It uses the following techniques:
- Quality-Aware Transcoding to deliver video in the most efficient codec without degrading quality. This reduces the video traffic load on the network.
- Dynamic Bandwidth Shaping to match the video bit rate to the amount of bandwidth available in the network. This minimizes video stalling and improves the customer experience.
- Video Caching to reduce the amount of bandwidth consumed in the packet core and the Internet backhaul. This improves the customer experience by moving content closer to the customer.
Web Optimization (3G EVDO only)
Web Optimization includes a vast array of techniques to streamline web page downloads and reduce the amount of data transmitted in the process. If the object is present in the cache, it is served from there. If not, the object is fetched from the content server to be optimized. The optimization process goes through four different optimization stages:
- Object Optimizations: Web pages consist of many objects (markup, images, scripts, video, etc.). Each supported object is individually optimized using a number of different techniques as applicable. For example, nonessential content (such as comments and white space) is removed, images may be compressed to reduce their size, text and other objects are compressed using Gzip, and so on.
- Page Optimizations: The various objects are combined to make a web page. Many optimizations are performed during the combining process. Several objects are prefetched even before the browser requests them to speed up the download. The objects are also grouped together and sent in one package to reduce the back-and-forth traffic and time involved in downloading one object at a time. Further, the downloading of the objects that make up a page is scheduled so that the page starts rendering as soon as possible.
- Protocol Optimizations: Once the page has been packaged, other optimizations are performed in its download to the device. For example, many objects may be downloaded simultaneously using pipelining. Sophisticated connection management techniques are used to control the number of connections used during the download to minimize connection overload while also decreasing page download time. Objects are downloaded in an optimal order for greater efficiency.
- Transport Optimizations: Further optimizations are performed in the transport layer itself. A type of Transmission Control Protocol better suited for wireless networks is used. Multiple responses may be combined into one packet to reduce the packet overhead. All of these optimizations combine together to download a page that consumes far fewer network resources and loads significantly faster.
What Are the Performance Characteristics of U.S. Cellular's Mobile Broadband Internet Access Service for Download and Upload Speeds and Latency?
U.S. Cellular gathers data about the performance of its Mobile Broadband Internet Access Service periodically for both the 4G LTE and 3G EVDO networks it operates within its licensed footprint. Recent network performance for download and upload speeds and latency can be reviewed by Cellular Market Areas using the table below. U.S. Cellular will update this data quarterly.
|Peak Usage Period||6 – 12 AM CST|
|CMA-FCC_Name||CMA_State||Downlink Throughput in Mbps||Uplink Throughput in Mbps||Latency in msecs|
|25th Percentile||75th Percentile||25th Percentile||75th Percentile||25th Percentile||75th Percentile|
* All other CMAs within the U.S. Cellular footprint have a population density of less than 250 people per square mile and the results for these CMAs and have been combined
* Generally, over 90% of U.S. Cellular's data traffic is carried by our 4G LTE network. Only approximately 10% of our data traffic is carried by our 1X-EVDO ("EVDO") network. When customers' devices use our EVDO network, the typical speed range that can be expected is between 600 kbps and 1.2 Mbps download and between 400 kbps and 600 kbps upload throughputs. This information is the best approximation available to U.S. Cellular of the actual speeds experienced by our customers.
The network performance is expressed as a range of speeds, based on actual network performance as measured by a third-party vendor. The speed within the range that an individual customer should expect to receive is influenced by many factors, including but not limited to, the customer's distance from a cell site, the number of customers accessing the network or a specific cell site at a given point in time, the amount of data consumed by applications run by a customer, and other factors affecting mobile wireless network performance. Performance may also drop below speed range at peak usage times.

Does U.S. Cellular ever reduce speeds (throttle) the Mobile Broadband Internet Access Service it provides to customers?
U.S. Cellular may intentionally reduce speed for Mobile Broadband Internet Access Service under the following circumstances;
- When the terms and conditions of the data plan that the customer has subscribed to permits U.S. Cellular to reduce speeds after a specified amount of data usage has occurred. For example, U.S. Cellular currently offers a pre-paid plan with unlimited voice and text and a fixed amount of high speed data. When the amount of high speed data contained in the plan is consumed, any remaining data consumed in the month, both downloads and uploads, may be reduced to a slower speed.
- When the customer exceeds a certain amount of data while roaming as provided for under the terms and conditions of the plan that the customer has subscribed to, or as specified in the customer service agreement that governs the provisioning of Mobile Broadband Internet Access Service by U.S. Cellular.
While U.S Cellular reserves the right to take reasonable actions to reduce data speeds to alleviate significant network congestion, U.S Cellular does not do so for either the 3G EVDO or LTE networks that it operates currently. Should circumstance dictate a change in this policy, U.S. Cellular will revise its posted Mobile Broadband Internet Access Services Open Internet Practices accordingly.
