Technology FAQs

What is multicasting?

In computer networking, multicasting (one-to-many or many-to-many distribution) is group communication where information is addressed to a group of destination computers simultaneously. WiDOX 3.1 technology allows the delivery of the same multicast data to all subscribers at the same time.

What is adaptive modulation?
Link adaptation, or adaptive modulation and coding (AMC), is a term used in wireless communications to denote the matching of the modulation, coding and other signal, and protocol parameters to the conditions on the radio link (e.g., the path loss, the interference due to signals coming from other transmitters, the sensitivity of the receiver, the available transmitter power margin, etc.)

What is the difference between clear line of site (LOS) and near line of sight (NLOS)?

Near-line-of-sight (NLOS), sometimes called non-line-of-sight, is radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. Note, with near line of sight, the wider Fresnel pattern results in many obstructions being accommodated, for example this means loss due to foliage, buildings, and small hills is significantly reduced. Near line of sight also requires a very low Rain Fade and design margins can be 6dB or less.

Clear line of sight (LOS) is radio transmission across a path that is unobstructed. Many types of radio transmissions depend, to varying degrees, on line of sight between the transmitter and receiver.

Both the WiDOX 3.1 and MiLTE solutions operate on near line of sight.

What is DOCSIS

The original definition of DOCSIS is Data Over Cable Service Interface Specification. DOCSIS is one of the most widely deployed transport and physical layer protocols in the world, used in cable TV systems (tens of millions deployed), satellite communication (WildBlue), data over power line, and wireless (WiDox).

What is the difference between EuroDOCSIS and DOCSIS?

EuroDOCSIS uses 8 MHz channels, and DOCSIS uses 6 MHz channels.

What are the benefits of using full duplex DOCSIS 3.0 system for wireless connectivity? 


  • It allows a much higher throughput
  • It allows multiple upstream and downstream channels bonding capability to increase bandwidth, maintaining the maximum possible speed (operates in multiple channels simultaneously for download and upload)

What are the benefits of using full duplex DOCSIS 3.1 system for wireless connectivity?

This is a new generation of cable technology with many benefits.

        • Enables higher speed connections:
                • Significantly reduces network delays as data traffic grows (increase responsiveness and higher resolution graphics)
. Improves responsiveness for a variety of applications
                • Transmits up to 33 percent more data throughput over the same spectrum. Can use up to 256 QAM for downstream and up to 32 QAM for upstream data.
                • Downstream and upstream traffic allows the use of OFDM. OFDM technology has the ability to rebuild corrupted service signals.
                • Supports: IPv4, IPv6, ICMPv6

What is full duplex and half-duplex?

Full-duplex allows simultaneous transmission and reception and maintains consistent high data rate to the edge of service area/distance subscribers, whereas half-duplex allows only transmission or reception to occur and may not maintain full data rate consistently to the edge of service area/distance subscribers. WIDOX 3.1 is a full-duplex solution and MiLTE is a half-duplex solution.
