1 FWA - technology and benefit Professor Torleiv Maseng adj. Professor radio communications Department of Electroscience ( Inst. för Elektrovetenskap), Lund University, LTH
2 FWA: Point to multipoint systems 5-20 km WWW, Internet, broadband services Source: PTS
3 Telecom in trouble
4 What went wrong? We are offering a product which few asks for (yet) for a price that nobody is willing to pay
5 What is the solution? Offer a popular product for lower price, enabled by new technology
6 Fixed Internet access is such a product Which access technology is the cheapest considering bit-rate, distance etc?
7 Plain old telephone is such a product In the future basic telephone calls will be carried by Internet
8 Residential fixed broadband access alternatives Access Technology Assessment Twisted copper pairs, xdsl Short range and low rate Coaxial cable, cable-tv Low rate Fixed radio access, FWA Expensive Fibre to the home Very expensive Power distribution cables EMC problems Broadband satellite access No return link Source: NTNU, Department of Telecommunications
9 No single access technology will take the whole market The choice of access technology depends on demography and geography 100% wireline Network investment ILLUSTRATIVE 100% wireless Hybrid networks combine the benefits of different access media and technologies Hybrid networks provide the most cost efficient alternative Hybrid network ~30% wireless Wireless percentage Source: Nera, PTS
10 Twisted copper pairs, xdsl ADSL 256 kbit/s - 8 Mbit/s downstream (asymmetric) all the way from central office to subscriber VDSL + fibre to the curb up to 52 Mbit/s on hybrid copper - fibre VDSL + inverse multiplexing up to 52 Mbit/s on copper all the way from central office to subscriber SHDSL symmetric bitrates from 192 kbit/s to Mbit/s Source: NTNU, Department of Telecommunications
11 Coaxial cable, cable TV Total bandwidth =< 4 Gbit/s (=<100 channels, 40 Mbit/s) Tree structure of cable network Shared capacity (different users + upstream - downstream) The cable TV network may provide broadband with broadcast TV in parallel Source: NTNU, Department of Telecommunications
12 Assumptions Frequency (MHz): Wavelength (m) 0,125 0, ,06 0, Antenna Hight Tx (m): Antenna Hight Rx (m): Transmit power (dbm) Antenna gain Tx (db) Antenna gain Rx (db) Sensitivity (dbm) Max prop. loss (db): Depth of vegetation (m) 50 Loss due to vegetation (db): 21,6 24,2 26,9 33,6 Maxloss (db):
13 Free space propagation loss margin (incl. some vegetation loss) Considering some vegetation loss, low frequencies are better than high! 2.4 GHz 3.5 GHz 5 GHz 10.5 GHz Margin (db) Distance (m)
14 The price of a network depends on the range and.. Price 2,4 3,5 5 10,5 28 GHz
15 and hardware cost Ref: C Brylinski and Thales, from; Elektronik i Norden 23 Aug 2002.
16 Fixed Wireless Access, FWA 1 Wireless access to fixed terminals Broadband access (up to 100 Mbit/s) Large areas a base station can cover km 2 Rapid deployment Well suited for areas where other broadband deployment is impossible or not economically feasible But, close to line of sight necessary for current solutions Source: NTNU, Department of Telecommunications, PTS
17 Fixed Wireless Access, FWA 2 Main frequency bands already allocated High frequencies (25-50 GHz) lead to expensive solutions Alternative frequency bands unlicensed bands at 2.5 and 5 GHz licensed bands at 3.5 and 10.5 GHz Rapid development of new technologies smart antennas (adaptive) mesh-technology (relay) mass production of microwave devices Source: NTNU, Department of Telecommunications, PTS
18 Broadband access in different flavours and environments 10 Gbps 1 Gbps 100 Mbps Fiber 10 Mbps 1 Mbps 0,1 Mbps FWA xdsl, cable-tv Copper access Core networks Cities Residential Rural Sparselypopulated Source: Nera, PTS mm
19 Broadband access coverage Network example in Norway PtP+FWA 36 Mbps per radio node Approx 5 km distance Speeds of 2 Mbps 3.5 GHz licensed band Several virtual LANs Secured by crypto Very simple to use Cheap compared with all other alternatives Quick to deploy Point to multipoint cell giving subs 2 Mbps wireless internet access Source: Nera
20 Multipoint to multipoint systems (Mesh) WWW, Internet, broadband services Source: Nera, PTS mm
21 Conclusions 1 Unlicensed bands Inexpensive equipment, readily available No quality of service, interference Free access to frequencies, congestion Licensed bands < 11 GHz Good solution for rural areas No standard equipment Licensed bands > 11 GHz Attractive capacity, but too expensive equipment Wait for next generation systems (3G=UMTS) Source: Nera, PTS
22 Conclusions 2 WLAN IEEE802.11b at 2.4 GHz is a success FWA: 3.5 and 10.5 GHz might become a success The success of IEEE is still to be proven FWA at millimetre/centimetre wavelength will compete/complement with VDSL There will be a mix of systems, the winners will be those which are cheapest!
