A new technology for home networking. It works!
Today
• Home Networks expand quickly – over 40% of Home Broadband
Subscribers
• Wireless Networking is utilized widely• Less than 35% of users implement
wireless security• Structured wiring continues to lag in
new home construction• More and more products are
launched with Ethernet connections
