Ø

LINKED CAPACITY PLUS OVERVIEW System Loading Ø
An LCP system handles Local calls as efficiently as Cap+, therefore if all calls are Local, T = the sum of the number of radios supported by each individual site. §
Ø
Ø
The number of radios supported by a given LCP site = the number of radios supported by a Cap+ system having the same number of trunked channels.
If there are Wide Area calls, T is estimated by first estimating R for a Cap+ system having N trunked channels. §
If all calls are Wide Area, T = R.
§
If there are a mixture of both Local and Wide Area calls, T = R*S (L + (1-L)/W)
Note: §
T = Total number of Radios supported by LCP system
§
R = Number of Radios supported by Cap+ system
§
N = Number of trunked channels at the smallest LCP site
§
S = Number of LCP Sites
§
W = Average number of Sites associated with Wide Area Talkgroups
§
L = Number of Local calls as a fraction of the total number of calls
LINKED CAPACITY PLUS OVERVIEW System Loading Example Ø
For a 5 site system where each site contains 12 trunking channels: §
Assume the loading for a 12 channel Cap+ system = 1,200 radios (note: this corresponds to low voice, low GPS & 5% GoS).
§
If all calls are local, LCP loading = 1,200 x 5 = 6,000 radios
§
If all calls are wide area, LCP loading = 1,200 radios
§
If 40% of calls are Local and Wide Area calls are setup over an average of 3 sites, LCP loading = 1,200 x 5 ( 0.4 + (1 – 0.4)/3) = 3,600 radios

LINKED CAPACITY PLUS BACK END NETWORK Considerations 1)
Master repeater - Must have a static IPv4 address Peer repeaters (and RDAC applications) - Either static or dynamic IP IPv4 addresses.
2)
Since LCP repeaters at a given site use IP Limited Broadcast address messages to communicate among each other, then: §
All repeaters pertaining to a given site must be behind a single Ethernet Switch/Router
§
The only devices that can be on the site’s LAN are the repeaters pertaining to that site (and any app ca ons
§
Hairpinning routers generally* do not need to be used
3)
Refer to the System Planner for details on recommended Switches/Routers. For constructing a small Linked capacity Plus demo system, the “NETGEAR WNR1000” Ethernet Switch/Router is recommended.
4)
Refer to the System Planner for details on how to calculate the bandwidth requirements of the backend network.
*
A Hairpinning router must be used at a site if that site contains multiple LCP devices and one of these
LINKED CAPACITY PLUS PROCEDURES Ø
A Wide Area Talkgroup call goes out on it’s (CPS configured) associated sites and only starts if channels are available at all associated sites. §
A configurable number of channels at each site can be reserved for Wide Area Talkgroup calls).
Ø
A radio tries up to 3 times to setup a call with random delays inserted in between each attempt.
Ø
An Individual call setup goes out on all sites where a channel is available. §
These sites all attempt a high-speed handshake (called “RTR”) with the target radio.
§
The site that succeeds with the high-speed handshake and the site where the initiating radio is located remain in the call while the other sites drop out (i.e. Dynamic selective site light-up).
§
The high-speed handshake occurs concurrently with the call set-up, so no additional
LINKED CAPACITY PLUS PROCEDURES Ø
“TRT” in Cap+ restricts the effect of collisions.
Ø
“Arbitration” in IPSC ensures that all the sites select the same call.
Ø
LCP improves and combines these two processes into a single process called “TR-A-RT”.
Ø
“TR-A-RT” can manage and allocate the channels for up to 5 concurrent calls (each occurrin at se arate sites in one arbitration.
Ø
The Wide Area Call setup time for LCP is approximately 240 ms more than for Cap+ (this increases where more than 2 concurrent calls need to be allocated).
Ø
The Local Call setup time for LCP is same as for Cap+.
Ø
A radio can receive a Digital Telephone Patch Call on any site, however a radio can only initiate a Digital Telephone patch call on a site connected to an APP (i.e. a radio can not initiate a Digital telephone patch call via an APP connected to a different site).

LCP only uses impolite channel access for emergency calls (where necessary). When a repeater detects an impolite call it updates the system call status to the new call. LCP frees up channels at associated sites (if necessary) during an emergency call setup. The start of an emergency call is announced over all busy channels at all associated sites, thereby allowing radios to leave their current calls and o n e emergency ca w ere app ca e . After setting up an emergency call, if there are no free channels left at a site then the busy rest channel shifts to a channel where there is a non emergency call in progress (thus ensuring that one emergency call does not clear down another emergency call).
No
Emergency Call transmitted impolitely over busy Rest channel.

Yes

LINKED CAPACITY PLUS PROCEDURES Roaming Ø
To minimise the amount of Beacon signalling
Ø
An LCP (Roaming) Beacon is appended to every 5th Cap+ (Lost Signal Detection) Beacon To facilitate faster scanning §
The Rest Channels at all the sites synchronise their Beacons § The LCP (Roaming) Beacons at a given site contain a list of Rest Channel IDs for that site’s neighbouring sites Radios use the list of Rest Channel IDs for a site’s neighbouring sites to determine which channels to scan when trying to roam using either Passive or Active Site search §
Ø Ø
The list of neighbouring sites for each site is configured only into the Master repeater (note: the Master repeater shares this information with all the other repeaters in the system)

LCP Beacon
LINKED CAPACITY PLUS PROCEDURES Roaming – Passive Site Search (Automatic Roaming) Ø
Radio builds up sorted roam list based on the LCP (Roaming) Beacons transmitted on the home site’s Rest Channels.
Ø
If home site signal strength drops below a programmable threshold, radio starts to scan through sorted roam list for a new site Ø
Radio only scans for a new site while in the idle state.
Ø Also,
the radio does not scan for new site if Site Lock feature enabled.
Ø
During Passive Site search, radio identifies site with strongest signal then makes that site its new home site.
Ø
Radio remains on the current home site and continues scanning until a better site is found.
Ø
While a radio is carrying out a Passive Site Search, it needs to leave its current home site for short durations which may cause the radio to miss activity on its home site (resulting in late entry to voice calls, or missed control/data).
LINKED CAPACITY PLUS PROCEDURES Roaming – Active Site Search Ø
Ø
Radio sends wake-up messages to each site in sorted roam list until it finds an active site. Active Site Search is initiated if Ø
a radio initiates transmission and it’s home site rest channel repeater can not be woken,
Ø
or a user initiates a Manual Site Roam (using the menu or a programmable button).
Ø
On waking a repeater, the radio synchronises itself with the repeater, completes the ransm ss on an ma es e new s e s ome s e.
Ø
If the end of the sorted roam list is reached and a site is not found, the radio provides the user with a failure indication.
Ø
Active Site Search does not necessarily find the best site, but rather allows the radio to move to the next “in range” site.
