Challenges for Wi-Fi, business models and spectrum issues

Enjeux économiques de Wi-Fi, modèles d’affaires et gestion de spectre

  • 68 Accesses

Abstract

Amongst the various versions ofWLAN, Wi-Fi is widely used and raises two interesting issues from an economic, strategic and regulatory perspective.

One deals with the perspectives of the two business models appeared so far: a cooperative, non-commercial one, for local use and a commercial one involving WirelessISPS and broadband access aggregators for roaming. Both show robust growth today but present weaknesses.

The other issue deals with spectrum allocation as Wi-Fi uses an unlicensed frequency band. Its development challenges traditional spectrum management, putting forward “open spectrum” management models. But while in theUS Wi-Fi has been able to develop without any significant regulation hurdles, the situation is more complicated in Europe and especially in France where regulation authorities have more recently addressed the issue.

Résumé

Parmi les diverses versions desRLAN (réseaux locaux radio électriques), Wi-Fi est très répandu et pose deux questions intéressantes des points de vue économique, stratégique et réglementaire.

La première porte sur les perspectives des deux business models apparus à ce jour: l’un est coopératif, non-commercial et utilisé en local; l’autre est commercial et fait intervenir des fournisseurs d’accès internet sans fil et des agrégateurs d’accès large bande pour l’itinérance. Les deux modèles se développent rapidement mais sont fragiles.

L’autre question porte sur l’usage du spectre car le Wi-Fi utilise une bande de fréquence partagée. Ce modèle «ouvert» remet en question les modèles traditionnels de gestion du spectre. Mais alors qu’aux États-Unis le Wi-Fi a pu se développer sans grand obstacle réglementaire, la situation est plus compliquée en Europe et particulièrement en France où les autorités n’ont pris position que récemment.
