Technology:
PHANTEQ’s distributed wireless access solution achieves high reuse
factor of the radio resource in any network topology and size.
Thus, costly and less efficient static or dynamic frequency planning
is avoided, and high throughput pervasive distributed wireless
networking is enabled.
The figure bellow shows the performance achieved by the solution
when considering a D2D network of 50 nodes using the
OpenAirInterfaceTM implementation of the 3GPP LTE uplink.
Indeed, the PHANTEQ’s MAC solution is proven to approach the
max-fair capacity of wireless ad hoc networks as the ratio ‘α’
between access opportunities period and transmission duration
decreases.
The max-fair capacity is achieved by a scheme that gives
instantaneous conflict-free and equal probability access to each
element in the competing sets of non-interfering links.
The lower bound considers the worst performance that a fair
random-access protocol following our solution may achieve. The
loss in throughput for a non-interfering set of K elements is
expressed as ∑ 𝑖𝛼(1 − 𝑒−1
)𝑒1𝐾
𝑖=1 .
As illustrated, PHANTEQ’s MAC solution achieves a high channel
reuse and approaches the capacity with decreasing ‘α’.
