SB4
- Need two rf switches
- each links matrix, 1 node, and 1 basestation
- all are controlled by raspberry pi, named sb4-cm
- Switch info
- Max RF input power 1w
- VDD 3.3v
- control voltage:
- Low 0-0.5v
- High 2.7-vdd
- Rf connectors SMA
- Control connector SMA
- pins for ground and vdd
- Raspi info
- 3.3 and 5v available
- gpio is 3.3v
- Software info
- TBD
WIMAX
- Use captured packet streams to control basestation.
- Write omf service to send these
- preferred method, once working, is to reverse engineer the commands.
LTE
- write omf service to control lte basestation parameters
- amarisoft, openairlte, airspan?
- primary openairlte
- https://twiki.eurecom.fr/twiki/bin/view/OpenAirInterface/OpenAirDocumentation
openair lte image, svn based new image, pull from git
repo1 oai images oa-trunk-full.ndz
replace with git based version
root home directory, git pull compile, put binaries in /usr/bin
3 important binaries
enodeb (basestation) ue (client) mme (component, mobility management, controller)
difference in compilation settings for enodeb vs ue vs cli switch
create via shell / ruby scripts to start server or client
control ue via resource controller control enodeb via rest?
both via conf. file
bsc03out has bs controller omf agg manager for conf, changes file, then controller
has version of bscontrol, managing amarisoft (n210) and oai (b210) or (x310)
bscontrol for (wimax airspan) airspan via snmp, adapt wimax commands for lte airspan
Switch Matrix
- need two non-blocking switch / attenuator matrix
- Connect B210s through switch matrix
- B210s have 2x tx, 2x rx
- 4 ports per b210, 2 ports per node
- compare pricing from DIY, minicircuits, jfw
- ex, 4 b210s
- set up two rails, 8 ports per rail, atten and delay between
- need price per attenuator.
