Title: TETRA Release 2 Overview
1TETRA Release 2 Overview
- Mark Edwards
- Principal Staff Engineer
- Motorola European System Design Centre
2Does TETRA1 handle data?
- Database look up
- AVL
- Email
- File transfer
- Limited slow scan video
- But some multimedia applications could ask for
more.
3Mission Critical Data Applications on TETRA
- Todays applications need data capacity
- Frequent messages, small payload
- AVLS from portables and vehicles
- Database access
- Status messaging
- But some applications starting to need more data
throughput - Less frequent messages, much bigger payloads
- Mug shots
- File transfer
- Slow scan video
TETRA Single Slot Packet Data
TETRA Multi Slot Packet Data
4TETRA2 brings new capabilities to Fire
5TETRA2 brings new capabilities to Ambulance
6Other Additional Applications of TETRA 2
7TETRA2
- TEDS (TETRA Enhanced Data Services)
- High Speed Packet Data for TETRA
8TETRA Enhanced Data Service - TEDS
High speed packet data service for TETRA enabling
faster data rate and higher data capacity
- Backward compatible with TETRA Release 1
- Network integration capability
- Flexible data rates and spectrum use
- 25, 50, 100 and 150 kHz channels bandwidths
- Can trade off data rate, spectrum and range
- Integrated TETRA 1 and TEDS system
- i.e. can receive TETRA 1 calls on TEDS channels
- Technology selected for TEDS use
- Multi-carrier QAM (Quadrature Amplitude
Modulation) in all bands - D8PSK in 25 kHz
9High Speed Packet Data Deployment
- TEDS will be the solution for mission critical
- A range of channel bandwidths available in the
standard - Offer a single TEDS channel at each site, in
addition to TETRA 1 voice channels - Provision channel bandwidth based on number of
users and their data application requirements - The modulation scheme can adapt to radio
transmission conditions
10GPRS versus TETRA - Availability
11GPRS versus TETRA - Predictability
12GPRS versus TETRA - Security
TETRA Availability Predictability - Security
13Typical upgrade to TETRA2
- Requirements from all users.
- Maintain GoS (Grade of Service) for voice and any
legacy data services - Increase capacity for new data services
- Easy upgrade
Your expectations for TETRA2
14Things to Remember
- New Spectrum
- Maintain present spectrum to keep GoS for
existing voice data services - New Terminals for TEDS services
- Retain present terminals for existing voice
data services
In partnership for TETRA2
15Spectrum Progress has been made..
- ECC (Electronic Communications Committee) has
just approved a Work Item to add support for
Wideband technologies in 385MHz 470 MHz - 385 MHz 390 MHz would be the ideal choice for
TETRA 2 - reserved for Nato
- Sporadically used at present
- users need to be very influential
- National regulators are responsible for
allocating spectrum - Will Consider the local operating environment
- Will Balance requirements from public safety,
transportation, etc.
Users need to exert their influence through the
MOU and directly to their National regulators
16The facts of life
- If you already have TETRA you will still be able
to use existing - Terminals
- Application
- Services
- When you get TETRA 2 you gain
- Data speed capacity
- New multi media applications
- Increased operational efficiency
- New possibility to innovate
TETRA 2 takes the lead
