Nokia has unveiled a range of wireless broadband products for telcos and ISPs, but a lack of spectrum in Europe could severely delay the products' launch here.
The range includes products for homes and businesses. Nokia's Rooftop system connects homes to the internet using routers attached to the side of a house. The routers combine a radio frequency modem with a digital IP router board and the Nokia Air operating system that routes IP traffic.
.Nokia's business connectivity product, Cityhopper, works on the same principle to create point to multi-point networks which the company claims addresses the 'last-mile' bottleneck to high-bandwidth access for businesses.
However, while Rooftop is being trialled in the US and Australia, the 2.4Ghz spectrum is not licensed and not widely available in Europe. Nokia would not specify when the products would be available in Europe, but said it would be some time next year. Cityhopper uses the licensed 10Ghz and 40Ghz spectrums.
Rooftop, rather than direct traffic to an access point as with existing connectivity systems, passes traffic along each router in the neighbourhood to get to its final destination. The technology can work if only two homes are participating in one street, but the system is more efficient if there are more routers, according to Nokia.
Wireless bridges are used to connect these neighbourhood networks together to a point of presence. Nokia claimed that this method "significantly" cuts the cost of using leased lines to link to points of presence.
The products are scheduled to ship in the US and Australia in the fourth quarter of this year.
