medium is from 6 Mbit/s at several hundred
metres up to 54 Mbit/s at 30 metres. The medium
is used for both vehicle-to-vehicle communication
carrying safety data, and for vehicle-to-roadside
communication carrying other data like Internet
access. This particular medium is amongst the
most interesting part of CALM, and a version or
subset of it will be selected for US deployment.
One interesting aspect is that the vehicle can connect
to a normal 802.11a access point even when
parking in your home garage. This group is led by
one of the authors of this article.
CALM InfraRed (IR) is a medium that is specifically
developed for CALM and ITS. It uses
850 nm in-coherent light with a data rate of
1 Mbit/s upwards, and communication distance
from 10 metres upwards. The main benefit is
that IR is not under regulatory control yet.
UMTS or 3G is also part of the CALM scope
as a convergence layer is created on top of the
UMTS protocol stack will interface the common
Service Access Points. This is being done in liaison
with ETSI, the European Telecom Standardisation
Institute.
Also 2/2.5G cellular, more commonly known as
GSM/GPRS, are part of the scope. Also here the
normal communication stacks of ETSI are used,

but an additional convergence layer is being
defined as an interface to the SAPs.
Each of the media have their own management
to control the behavior, such as frequency and
power control.
The binding “glue” in this architecture is the network
layer. One of the first decisions were to use
IPv6 which is the new Internet standard that
removes the old problems of limited numbering
space. It also added a lot of very useful facilities
for mobile environments like Quality of Service,
Security, Mobility addressing, etc.
The “intelligence” in the architecture is the
CME, or CALM Management Entity. This module
will record the capabilities of each connected
medium in terms of data rate, QoS, cost etc, and
then match this with the requirements from the
applications running on top of the stack. It will
also decide on heterogeneous handover in case
a homogenous handover at the MAC layer is not
possible.
Figure 5 shows some of the applications that
were included from the start. Since this time,
many new safety applications have been introduced,
and the case of Internet in the vehicle has
