|
|
System | Network | Device |
(i) Physical phenomena of wireless
channel—variability (affected by
noise, fading, and interference) | (i) Signal strength (terminal antenna
gain, terminal receiver sensitivity) |
(ii) Wireless channel reliability
(interception, security issues) | (ii) Battery lifetime—energy
consumption |
(iii) Wireless capacity (speed, coverage,
limited bandwidth, shared resources) | (iii) Computational power/resources,
storage capacity, processor capability |
| (iv) Channel sharing among users | (iv) Screen and keyboard size |
(v) Signal strength (affected by the
temperature, humidity, distance from
the antenna, base station antenna gain) | (v) Signaling traffic overload |
| (vi) Signaling traffic overload | |
| (vii) Handover delay | |
| Media and Content |
(i) Adaptation capabilities (e.g., capability to adapt various application parameters to
fit the device, network, usage context constraints) |
|
(ii) Usability of mobile device |
|
(iii) Adjustment to the device power consumption |
|
(iv) Data access |
|
(v) Offline capabilities |
|
(vi) Transparent synchronization with backend systems |
|
(vii) Security issues |
|
(viii) Lack of add-ons |
|
| User and context |
User routine and lifestyle |
The impact of multiple contexts on user's perception (e.g., mobility, time of day,
noisy environment, prior experience) |
