SNOM M700 DECT

Short introduction to DECT Multi-Cell

Understanding Multi-Cell Coverage: 100 m indoor, 300 m outdoor

M700 base stations

Understanding Multi-Cell

Coverage

• 100 m indoor / 300 m outdoor

• Roaming among multiple BS

SIP registrations

• Max. 30 per base station• Distributed

automatically BS

Voice Channels per Base

• Up to 8 concurrent calls (4 HD audio)

100 m100 m

1-30

Max. 1,000

4-8

Max. 200

SIP up to 30 SIP up to

30 SIP up to 30

Up to 30, but we need only one additional handset

Base station calculationHow many BS do you need for 91 handsets?

• SIP Registrations: 91/30 = 3 x 30 + 1 x 30 –> 4 Bases• Best practices for heavy call usage: 8 per Base –> 11

Bases

DECT assessment @ location

Assessment

• Base with local power• Handset in assesment

mode

Assessment Goals

• Redundancy per Base• Coverage approx. -70dB to be safe• Floor to floor , building to building connections• Full air coverage auto-DECT tree

Assessment Do‘s

•Handset / Menu, *IP* (*47*)• Select your base station• 2x Call button for audio loop-back with your base• Look for good reception to two other bases•Direct hall-way coverage (tends to be very far and safe)• floor to floor• Very near Fire safety door / behind elevator / open space backyard

Assessment Dont‘s

•Guess-work base placement – always assess!• Non redundancy radio coverage -80dB• Direct path base station over the air DECT tree• Human bodies coverage reduction• Underestimate concurrent call areas•Multi primary where not necessary

…Air sync No Air sync

Over the air syncMandatory for Roaming

• There is sync over LAN, but its limited to max bases-1• In fact, hardly a limit

Multi Primary

Up to 1000

…Primary

LAN sync

More than one data master on the LAN

• The master base stations MUST NOT „see each other“ over the air. This will cause syncronisation chaos within the Multi-Cell installation
