Today, most of the operators provide more than one service to increase their revenues. Almost every operator provides an Internet service as of 2019. These operators can be any of the following types: Landline Phone Companies Cable Companies Cellular Phone Companies Satellite Companies Service Providers provide different types of services. Some Service Providers provide broadband services, while others provide mobile services, cloud services, edge computing, VPN, Internet or hosting services Companies generally provide more than one type of broadband access to their customers to increase their revenue In this module, we will look at different types of fixed and mobile based broadband services such as XDSL, FTTX, Cable Broadband, Fixed and Mobile Satellite, Wireless Internet Service and Mobile Broadband LTE (Long Term Evolution) Broadband signals compared to narrowband signals have much more band in the frequency spectrum Thus, the term is referred as broadband Higher band in the frequency spectrum allows faster data communication. Early Dial-up modems (over telephone lines) worked based on narrowband, thus they only provided voice communication and slow data speeds such as 56kpbs Broadband allows much higher data speeds such as 1Gbps or even more DSL, FTTX, Cable Broadband, 3G, 4G Mobile Broadband are the examples of broadband technologies These technologies will be covered in detail later in this module Carrier and ISP are very commonly used terms in the industry. There is a difference between them. Carrier is the company that owns the phone lines and maintains them. Service Provider is the company that is responsible for making sure that the services (such as voice, VPN and Internet Service) are functioning properly.
