Comparison
Internet
service today is delivered via
the following methods:
POTS (plain old telephone
service). This is dial-up service,
shared with regular voice service.
DSL (digital subscriber line).
This is a high speed service
offered over telephone wires,
operating on a different frequency
than voice.
Cable (coax). This is a high speed
service transmitted over cable
television wires.
Terrestrial Wireless. This is
radio frequency transmission
between ground based stations,
typically at high frequencies.
Speeds range from slow (cellular
services) to high speed WiFi and
WiMax. Numerous standards exist.
Orbiting Satellite Wireless. This
is radio frequency transmission
between ground and space based
stations, always at high
frequencies. Some are
bidirectional, while others are
download only and rely on POTS
dial-up for the uplink.
Powerline Ethernet. This is data
transmission over power lines. Not
widely deployed. Typically limited
to interior networking to extend
service within the premises.
FiOS (fiber optic service). This
is transmission over fiber optic
cable. Not widely deployed to
residences yet, but slowly
expanding in heavily populated
areas. Generally faster than other
methods. The preferred option if
you can get it.
Rebus
Communications is a terrestrial
wireless service. What makes us
different?
Rebus Communications does
not cap your transfer speeds.
Everyone gets high speed.
DSL (telephone provider) speeds
slow the further your line length
to the central office. Actual
speeds are often less than even
the low capped maximum. DSL,
cable, wireless and satellite
services typically offer a tiered
pricing structure, charging more
for higher speed caps. We instead
rely on sophisticated Quality of
Service management policies that
prioritize traffic based primarily
on delay and throughput
sensitivity. This way you can be
sure to get the maximum available
download speeds when web browsing
or downloading video yet not
suffer Internet telephone (VoIP)
drop-outs from local causes.
Rebus
Communications network latency
is low.
Satellite service
inherently has very high latency
(several seconds for each packet
to travel to its destination).
While sustained file downloads are
reasonably fast once underway, web
browsing is not much better than
dial-up speeds. This is because
web pages are made up of many
small pieces, each of which are
delayed, resulting in large
cumulative delay in rendering a
complete page. Internet gaming and
VoIP phone service are not
practical. Cellular wireless has
varied periods of high latency,
frequent during high traffic
periods, and occasional dropped
connections (just like your
cellular telephone calls).
Rebus Communications total latency
across the network is only a few
milliseconds and stable.
Rebus
Communications does not
oversubscribe.
We limit the number of
clients to minimize impact from
other users.
All services, no matter the type
or provider, are shared. Generally
speaking, the more subscribers the
slower the overall service,
particularly during peak usage
times.
Rebus
Communications does not restrict
certain types of legitimate
traffic.
Most DSL, wireless and
satellite services have a low
speed cap on certain types of
traffic such as FTP, SSH, IMAP,
etc., or in other words, file
transfers, E-mail and newsgroups
to prop up their HTTP (web
browsing) speeds. Rebus
Communications employs intelligent
quality-of-service traffic
management that actively
prioritizes on-the-fly. No fixed
caps.
Rebus
Communications does not apply
excessive port blocking.
Most wireless and
satellite services block all but
the most common ports to the
Internet. This means that some
available online services and
applications will not work. DSL
and cable providers are
increasingly adopting this policy
as well. Rebus Communications
employs intrusion protection
traffic monitoring at the head end
to protect the network from
unauthorized traffic rather than
simple port blocking.
