  station.

29
Repeater Stability

• SpotCell Adaptive Repeaters operate with a
  constant safe stability margin
• Isolation is continuously monitored.
• If isolation is reduced, system gain is reduced
  to maintain stability margin.
• Output noise is reduced under these conditions.
• Waveform integrity is maintained

30
BDA Performance Limited Isolation

• Non-Adaptive Repeaters will create added network
  noise if the stability margin is poor.
• Power based detection methods do not prevent this
  (until a full oscillation is detected)
• Up to 10dB excess noise can be produced
• Limits no. of systems that can be safely deployed
  .
• SpotCell Adaptive Repeaters provide constant
  stability margin.
• Network noise is REDUCED if the isolation is
  reduced.

Uplink Noise vs. Isolation

• Uplink noise increases well before the
  onset of oscillation in a non-adaptive repeater.

Small Office

• One or Two floors 25,000 50,000 sq ft.
• Metal / concrete construction
• Several donor BTS candidates
• Low RSSI suburban locations low pilot
  pollution
• Or, strong RSSI high pilot pollution.
• Roof mount or window mount DU.
• CU in ceiling space or on wall.
• Moderate traffic levels (typically 10-50 users
  per site)
• One or two SC2500/5000

SpotCell sized to an individual office Usually
leased and part of a larger building. Indoor DU
location minimizes site acquisition issues.

installation.
48
Warehouse, Big box retail

• Single floor plan up to 200,000 sq ft.
• Only partial coverage is required.
• Low capacity requirement

• Low moderate RSSI suburban locations
• Several donor BTS candidates
• Roof mount DU.
• CU in ceiling space
• Extended cable runs
• Expanded coverage footprint in open buildings
• One or two SC2500/5000

SpotCell often used where only partial coverage
required- wireless retail outlet System
architecture allows coverage to be easily
expanded.
49
Campus

• Multiple small buildings or islands of coverage
  within buildings hospital campus.
• Suburban environments low signal, low pilot
  pollution good coverage.
• Multiple SpotCell systems required different
  sites.
• Moderate capacity requirement.
• Aggregate coverage may be up to 200,000 sq ft.

Using multiple SpotCells is more cost effective
than a DAS system where coverage requirements are
fragmented. Multiple DUs allow traffic load to
be distributed among different BTS.
50

  local BTS
• Ensures repeater Ec/Io gt -7 dB
• Plenum cable runs
• Coverage signal 5dB above ambient signal level
• 2 x SC5000 needed per floor

DU antenna pattern allows systems to be installed
with major down tilt Limits donor footprint to a
single block (BTS) Coverage can be provided in
difficult conditions with good signal quality
(Ec/Io).
