Key Takeaways:

  • ISDN (Integrated Digital Services Network): An older digital telephone technology offering relatively low bandwidth.
  • DSL (Digital Subscriber Line): A family of technologies using existing telephone lines to deliver high-speed data.
  • MMDS (Multichannel Multipoint Distribution Service): A wireless broadband technology that provides internet access over a wide area.
  • LMDS (Local Multipoint Distribution Service): A wireless broadband technology designed for high-bandwidth, short-range applications.
