Abstract• Market requires more functionalities
and performance.• Current requirements discussed in
WNG are not enough.• Global Area Network (GAN) concept
depicts more requirements.• GAN concept is proposed for
discussion base within WNG.

Open Questions• Do we want single standard and/or Roamable
standards? Either or Both?• Do we have more scenarios?
– Airplane? Rural area? Under the sea/ground? In the space?
• Do some of us need to stick to universal service?– Some operators yes…?
• Do we need to collaborate with other bodies such as 3GPP, IETF, etc.
• Are we talking “When”?• Spectrum discussion?
– ISM bands? UWB? 5GHz? New bands?

Conclusion• Market requires more functionality and
performance.• Current requirements discussed in WNG
are not enough.• GAN concept depicts more requirements.
– Global seamless roaming– High mobility
• GAN concept is proposed with open questions for discussion base within WNG.
