These services share AT&T’s network infrastructure and may rely on network practices to assign different levels of priority dynamically or statically. End-to-end performance of your service depends on a variety of factors, including: the number of subscribers simultaneously using the network customer location destination and traffic on the internet Wi-Fi connectivity the capabilities and performance of your Local Area Network (LAN) interference with high frequency spectrum on your telephone line wiring inside your premises, office or apartment the capacity or performance of your devices or modem the server with which you are communicating internal network management factors (including overhead, which refers to the various control and signaling data required to achieve the reliable transmission of internet access data) and the networks you and others are using when communicating.ĪT&T offers a wide variety of services to its customers over AT&T's network infrastructure including Voice over Internet Protocol (VoIP), Internet Protocol (IP)-video, unified messaging, Voice over LTE (VoLTE), enterprise networking, public safety (including FirstNet), and national security services. Your service capability speed may not be suitable for some applications, particularly those involving real-time or near real-time, high-bandwidth uses such as streaming video or video conferencing.īecause service performance varies on an end-to-end basis, AT&T’s service capability speeds are limited to, and measured between, your location and a point on AT&T’s network, which constitutes only one segment of the end-to-end transmission path connecting your location to internet websites or content providers. Other activities, like transferring large data files, can be performed faster with higher-speed services.
Some applications, like a short email without attachments or basic web browsing, do not require high service capability speeds to function optimally. This capacity is typically measured in the number of kilobits, megabits or gigabits that can be transmitted in one second (Kbps, Mbps or Gbps).
The term speed is commonly used as a shorthand way to describe the capacity at which a particular mass market broadband internet access service can transmit data. What factors affect the performance of my mass market broadband internet access service?ĪT&T offers many mass market broadband internet access service options, each of which may have a different service capability speed.
