Bolero Facts and Figures

Standalone Link Mode

Timeslots

Bolero wireless intercom 1.9GHz is based on DECT (Digital Electronic Cordless Technology)

In the UK there are 10 DECT frequency bands, each of which has 10 useable timeslots (there are 12 timeslots in each band, but 2 are reserved for seamless transfer and roaming between antennae.)

Modes of Operation

There are 3 Bolero modes of operation: Integrated Artist (used with a Riedel Artist frame) Standalone Link and Standalone AES 67.The absolute maximum number of antennae in a NET is 100.  Given the number of frequency bands, the maximum beltpack count is 100.

	Integrated Artist	Standalone Link	Standalone AES67
Maximum Antennae	100	100	100
Maximum Beltpacks	250	100	100
Partylines	500 (Conferences)	12 (Up to 32 can be licenced)	12 (Up to 32 can be licenced)
NSA-002	N/A	10	10
AES67 Switch	Yes	No	Yes
Antennae POE+	Yes	No	Yes
Standalone Licence Required	No	Yes	Yes

Up to 10 io devices and 128 channels can be managed in one network space.  If 10 NSA-002 are used, 10 x 6 audio channels equals 60 channels leaving 68 channels for beltpacks.

Standalone Link Mode

This can be used without a switch (up to 5 antennae.)

Up to two IO devices per Bolero Antenna. Connect the first io device (ETH1/2port) directly to the antenna (AES67/Config port).

Connect the second io device (ETH1/2port) at the unused ETH1/2 port of the first IO device.

Antennae are connected using the link ports., port 1 of the first to port 2 of the next and so on, up to a maximum of 5. Note that antennae and NSA-002 devices need to be powered locally in standalone link mode.

Antenna Placement

Antennae that are fully separated, i.e. no overlap will not interfere with each other.

As the antennae are brought closer together the signals overlap and interference occurs.  This will start at a power differential of -15dBm.  If the power difference is less than this no interference will occur and antennae in the neighbouring space can use the same frequencies and timeslots.

Antenna Power Level

Bolero antennae can operate at three power levels.

-20dBm normal

-13 dBm low

-6 dBm ultra low

Consider the case with a finite area with full separation of antennae.

At high power only 2 antenna can be positioned, meaning 20 belt packs can be connected.

If the power of the antennae are reduced, more can be fitted into the same space, without interference which allows more belt packs to be connected.

The power level can be adjusted for the network space, not for individual antennae within that space.

Updates

The release notes in a firmware update are a good place to check for updates to Bolero operation.

Things to note:

You are still able to program a NET for future use, even if you don’t have access to a Standalone Antenna. Though there is no way of programming a bolero NET offline, you can create one, including partylines, NSA/harware profiles and Beltpack profiles by connecting to a spare non Standalone Antenna.

It will tell you that the licence is missing and won’t let you register beltpacks, but you can program all of the above and save the NET config to your laptop. All you’ll have to do at the other end is a factory reset on the standalone antenna, upload the config and add your beltpacks and NSA’s to the profiles created.

CAUTION! Nets created on up to date firmware cannot be loaded onto antenna running order versions. Make sure you are always running the latest firmware.
