Broadband performance booster
Millions of UK households could benefit from improved broadband performance, thanks to a simple, self-install filter developed by BT Wholesale.
The patent pending innovation - called the I-Plate - filters out electrical interference caused by televisions, lighting and home wiring, which can often slow down broadband speed and affect the stability of the connection.
Cameron Rejali, managing director of products and services for BT Wholesale, said: "The launch of the I-Plate is another example of BT's drive to deliver enhanced broadband services to UK homes."
"Most consumers are unaware of the impact that faulty TVs, fluorescent lighting and home wiring can have on their broadband performance. The I-Plate can help solve this, depending on the level of electrical interference within the home, delivering faster speeds, greater stability and bringing high-quality internet protocol television to more consumers." 
BT's trials of the I-Plate have shown that filtered lines can deliver a range of broadband improvements, including faster speeds, a more stable broadband connection and slight improvements in broadband performance over 'long lines'.
