  2. Internet access - Local Multipoint Distribution Service • Local Multipoint Distribution Service https://store.theartofservice.com/the-multipoint-toolkit.html

  3. Internet access - Local Multipoint Distribution Service • Originally designed for digital television transmission (DTV), it is conceived as a fixed wireless, point-to-multipoint technology for utilization in the last mile https://store.theartofservice.com/the-multipoint-toolkit.html

  4. Internet access - Local Multipoint Distribution Service • LMDS has been surpassed in both technological and commercial potential by the LTE and WiMAX standards. https://store.theartofservice.com/the-multipoint-toolkit.html

  5. Multichannel Multipoint Distribution Service • Multichannel Multipoint Distribution Service https://store.theartofservice.com/the-multipoint-toolkit.html

  6. Multichannel Multipoint Distribution Service • Multichannel Multipoint Distribution Service (MMDS), formerly known as Broadband Radio Service (BRS) and also known as Wireless Cable, is a wireless telecommunications technology, used for general-purpose broadband networking or, more commonly, as an alternative method of cable television programming reception https://store.theartofservice.com/the-multipoint-toolkit.html

  7. Multichannel Multipoint Distribution Service - Technology • The BRS band uses microwave frequencies from 2.5 GHz to 2.7 GHz https://store.theartofservice.com/the-multipoint-toolkit.html

  8. Multichannel Multipoint Distribution Service - Technology • The MMDS band is separated into 33 6 MHz "channels" (31 in USA) which may be licensed to cable companies offering service in different areas of a country https://store.theartofservice.com/the-multipoint-toolkit.html

  9. Multichannel Multipoint Distribution Service - Technology • The newer BRS Band Plan makes changes to channel size and licensing in order to accommodate new WIMAX TDD fixed and mobile equipment, and reallocated frequencies from 2150 - 2162 MHz to the AWS band. These changes may not be compatible with the frequencies and channel sizes required for operating traditional MMDS or DOCSIS based equipment. https://store.theartofservice.com/the-multipoint-toolkit.html

  10. Multichannel Multipoint Distribution Service - MMDS and DOCSIS+ • Local Multipoint Distribution Service (LMDS) and BRS have adapted the DOCSIS (Data Over Cable Service Interface Specification) from the cable modem world. The version of DOCSIS modified for wireless broadband is known as DOCSIS+. https://store.theartofservice.com/the-multipoint-toolkit.html

  11. Multichannel Multipoint Distribution Service - MMDS and DOCSIS+ • Data-transport security is accomplished under BRS by encrypting traffic flows between the broadband wireless modem and the WMTS (Wireless Modem Termination System) located in the base station of the provider's network using Triple DES. https://store.theartofservice.com/the-multipoint-toolkit.html

  12. Multichannel Multipoint Distribution Service - MMDS and DOCSIS+ • DOCSIS+ reduces theft-of-service vulnerabilities under BRS by requiring that the WMTS enforce encryption, and by employing an authenticated client/server key-management protocol in which the WMTS controls distribution of keying material to broadband wireless modems. https://store.theartofservice.com/the-multipoint-toolkit.html

  13. Multichannel Multipoint Distribution Service - MMDS and DOCSIS+ • LMDS and BRS wireless modems utilize the DOCSIS+ key-management protocol to obtain authorization and traffic encryption material from a WMTS, and to support periodic reauthorization and key refresh. The key-management protocol uses X.509 digital certificates, RSA public key encryption, and Triple DES encryption to secure key exchanges between the wireless modem and the WMTS. https://store.theartofservice.com/the-multipoint-toolkit.html

  14. Multichannel Multipoint Distribution Service - MMDS and DOCSIS+ • MMDS was sometimes expanded to Multipoint Microwave Distribution System or Multi-channel Multi-point Distribution System.
