Overview
Swiss Universal Broadband Service Obligation:Understanding the demand of the Swiss Universal Service Obligation upon Swisscom
xDSL:Under what scenarios is xDSL an economical solution, and when does it become uneconomical?
WLAN:Where is WLAN an alternative?
What are its advantages and risks?
Discuss ongoing Swisscom trials with WLAN point-to-point connections combined with VDSL
WiMAX:Where does WiMAX become viable?
Present the Swiss Broadband Wireless Access license situation and the planned Swisscom trial
Satellite:Will a satellite service be accepted to provide broadband?
Fixed installed GSM: In total absence of copperlines, voice service is granted via GSM

Swiss Universal Service Obligation
Voice in today's USO:Wireline voice is in the Swiss Universal Service ObligationAll Swiss households have to be served with voice service for monthly 25.25 CHF ≈ 16 € basic rental fees
Broadband in 2008 USO:The Swiss government has decided in September 2006 to include broadband in the Universal Service Obligation as of 2008The minimum required throughput is usually 600 kb/s / 100 kb/s,with exceptions (150 kb/s / 50 kb/s ?) in very remote areas
The maximum allowed pricing is a monthly 69 CHF ≈ 43 €Switzerland will be the only country in the world with BB in USO
Provision of 2008 USO:By mid of 2007, the responsibility of 2008 USO will be given to a companySwisscom currently evaluates the conditions and will most apply for the2008 USO, yet may presumably also be forced for
Wireless alternatives:May wireless technologies be applied?Such as WLAN, WiMAX or satellite?
WLAN point-to-point trials:Performance: Europe vs. America
Measured throughput vs. distance

Conventional solution (optical fiber / xDSL):Pro: Technically best solution
Con: Digging optical fibers is time consuming and expensive feasible only if enough customers

Remarks:Standard: WLAN IEEE 802.11a (longer reach & less interference than 802.11g) + 802.11s (mesh option)Peak throughput: Around 20Mb/s per 20MHzDistance: Transmission powers limited for unlicensed bands limited distancesSpectrum: Unlicensed bands operation vulnerable to unwanted or wanted interference
Price: Relatively cheap due to mass marked volumes (≈700€ per WLAN AP, ≈300€ per antenna)
Scenario: Mesh option
WLAN Spectrum, Scenario & Remarks
Spectrum: Unlicensed spectra in the 2.4 GHz and 5 GHz bands.

Remarks:Standard: Mobile WiMAX IEEE 802.16e-2005 (preferable WiMAX option, leaves mobile application open)Peak throughput: 15Mb/s per 5MHzDistance: Higher transmission powers larger distances than WLANSpectrum: Licensed bands saver operation than WLAN License obligation: 30, 70, 120 cell sectors by end of 2007, 2008, 2009Price: Much more expensive than WLAN (≈40k€ per base station?)
Spectrum: Swisscom was the only bidder for a BWA license (6 Mio CHF≈4 Mio €) in June 2006.
*) From WLL auction in 2000; license runs out in 2010.
