Transcript BLOCKING UPSTREAN NOISE - Safecom

Safecom INGRESS GATE technology (Patent p)
UPSTREAM NOISE BLOCKER
Solving the “Funneling Effect” at HFC & RFoG networks
CLEAN UPSREAM = HIGHER SPEED BROADBAND NETWORKS
The Concept & Benefit:
Upstream gateway that fully synchronized with Cable modem. (patent p)
Enable upstream signal only when modem is active.
Blocking upstream & ingress noise by > 28dB without RF or mechanical switch.
Optimizing CMTS-CABLE Modem communication.
Solving the “Funneling Effect” at HFC & RFoG networks.
Lifetime operation.
Fast & Simple
Stand alone home upstream noise blocker or Ingress Gate embedded inside Home amplifier
(Active , Passive return).
 Self controlled without needs for expensive extra monitoring or complicated remote operational.
 Simple integration outdoor or indoor.
 Plug and play device.
 Best performance in the market.
 Low Cost.

About “Funneling Effect”
Coax
RF Noise
RF Noise from CATV subscriber homes flows into the network and blocking the upstream path.
“Funneling Effect” shows the structural failing of “the last two way signal over coax part”.
“Funneling Effect” slow down & interrupt upstream transmission of the internet.

“Funneling Effect” limits performance of the network, slowing and interrupt internet
connection while conceals the superiority of the CMTS-CM Model.
INGRESS GATE Eliminates “Funneling Effect”

Principle of solving “Funneling Effect” by safecom’s ingress Gate technology:
1.
2.
3.
4.
Ingress Gate turn ON upstream channel only when Cable modem is transmitting.
Ingress Gate keeps all other upstream paths closed, therefore only one path at a time can transmit a signal to CMTS.
Upstream gate controlled and synchronized with cable modem, EMTA & setup boxes.
Blocking uptream noise without RF or mechanical switch.
Ingress Gate technology blocks upstream noise by > 28 dB and eliminates the
“Funneling Effect”. Enables a clean and free upstream path for maximizing Internet
performance.

Gate
control
1. Ingress gate control turns upstream amplifier ON & OFF by controlling DC power without any RF
or mechanical switching.
2. When modem is not active upstream amplifier is OFF.
Result : RF noise cannot pass upstream amplifier to the network.

control
1. “Ingress gate control” turns upstream amplifier ON & OFF by controlling power of amplifier.
2. Ingress gate operation controlled and synchronized by cable modem.
3. When modem is active upstream amplifier is turned ON.
Result : Upstream RF pass to the network ONLY when Modem is active.
Testing INGRESS GATE Home Amplifier Procedure :
Combine two frequencies and measure noise level by Spectrum Analyzer.
