WirelessCabin Objectives
UMTS, W-LAN, Bluetooth access to specify a system for wireless aircraft cabin access (UMTS, W-LAN and
Bluetooth) to develop a system prototype and demonstrate the services to support mobile, collective networks on the move with protocols for
AAA, VPN, mobility, QoS to determine the aircraft indoor cabin propagation channel for UMTS and
ISM band to analyse the interference into avionics and terrestrial networks to determine the topology, the capacity and frequency assignment of cabin
cellular networks to define an encapsulation protocol to transport the UMTS over Bluetooth to investigate resource management schemes in the cabin

Business Modelling Ingredients
• Satellite system/constellation
– spot beam coverage
– flexibility of spot beams
• Multiservice traffic/capacity model
– demand-driven “forward” calculation
– essentially linear and parametric
• User demand model
– for voice, email, ftp, www
– based on measured demand figures from terrestrial provider
(national/international calls)
• Pricing/revenue model
– based on national/international call tariffs from GSM/GPRS perspective

Aircom Business Case Methodology
How much would customers really use aero services if:
1. Those services were charged like the equivalent terrestrial services?
2. Customers used the budgets they already have available for those services?
Steps:
1. Identify the equivalent services to aero Phone and Internet
2. Provide the tariffing & usage profiles for aero services
3. Map these profiles to the classes the passengers fly
4. Provide revenues and data traffic expected per aircraft, according to the typical cabin configuration
5. Extend the results to the fleets used for North-Atlantic flights

Results and Conclusions: Coverage
Propagation conditions in short and long range a/c are not comparable
A319: 1 AP per RAT is sufficient for coverage requirements
UMTS WLANA319
A330-200: there are coverage gaps providing even 4 APs for WLAN!!
Solution: Leaky line only 1 AP required

WirelessCabin – Success for European Industry
WirelessCabin has achieved profound impact in aviation industry.
At project start, only limited possibilities for wireless data communications were
available, and mobile telephony was considered as unlikely and risky.
Today,
WirelessCabin project has opened up a new business direction for airline
operators, manufacturers and telecommunications operators
support of standardization groups have paved the way for industrial roll-out of
services
major aeronautical service providers have mobile telephony on their roadmap
