Examples of map building and beacons’ placement
To make it possible for beacon to switch from the current submap to the neighboring one,
the uniqueness condition for the frequencies of neighboring submaps is required, i.e. for
any submap,
all adjacent submaps must not have repeating
sets of frequ jitter
codes + TDMA sequence
, it should be unique set for every submap
.
How to decipher the notation below:
Sets of frequencies:
-
Example 1:
In this example,
submap1
has two adjacent submaps with the same frequencies (19-
25kHz)
– It is
INCORRECT.
-
Example 2:
In this example, sets of frequencies are: 19-31kHz, 31-45kHz and 45-19kHz, while there
are no repetitions in adjacent submaps, while further construction of submaps using the
same frequencies is allowed, i.e. 19-31kHz, 31-45kHz, 45-19kHz, 19-31kHz, 31-45kHz,
45-19kHz, because in this case, repetition does not occur
– It is
CORRECT.
Jitter codes:
19(j0, T1)kHz
25kHz(j0, T1)
31kHz(j0, T1)
45kHz(j0, T1)
19kHz(j0, T1)
25kHz(j0, T1)
Submap0
Submap1
Submap2
The same frequency sets
The same jitter codes for beacons
The same TDM A sequence
Submaps the same - INCORRECT
19kHz(j0, T1)
31kHz(j0, T1)
45kHz(j0, T1)
19kHz(j0, T1)
Submap0
Submap1
Submap2
Different frequency sets
The same jitter codes for beacons
The same TDM A sequence
Submaps differ - CORRECT
19kHz beacon, jitter=0, TDMA 1
19kHz(j0, T1)
