+
+
+== Clasic E1/T1 based BTS
+
+Supported Vendors/Dialects
+
+* Siemens (only BS-11 tested)
+* Ericsson RBS2xxx (RBS2307, 2308, 2111 tested)
+* Nokia InSite, MetroSite
+

+|===
+|Pro|Con
+|available inexpensively from decomissioned sites | appears a bit antiquated
+|up to 12 TRX | not many people familiar with E1/T1 anymore
+|high RF output power | no convenient testing/debugging of E1/T1 issues
+|rugged mechanical build, high MTTF | high power consumption
+| | older models no EGPRS, no AMR

+== Clasic E1/T1 based BTS
+
+image::images/har2009-bs11_antennas2.small.jpg[width="50%",role="gimmick_right"]
+
+* This is how it all started
+* E1 based BTS (Siemens BS-11)
+* HAR 2009 - Dutch Hacker Camp
+* Antennas mounted with duct tape to tree
+* E1 back-haul over CAT5 to OpenBSC running in tent
+
+== Ericsson RBS 2308
+
+image::images/rbs2308.jpg[width="60%",role="gimmick_right"]
+
+* Many RBS2000 models
+* All very similar on protocol
+* Not all models tested
+* Good results with RBS2308 + RBS2111
+
+== ip.access nanoBTS
+
+image::images/nanoBTS_small.png[width="40%",role="gimmick_right"]
+
+* PoE-enabled single-TRX 200mW indoor BTS
+* GPRS/GSM only models and EGPRS-enabled models
+* available in band-specific versions for all four bands
+* proprietary BTS and PCU inside
+** lots of PCU crashes reported by users :(
+** no way for us to fix it
+* No fully dynamic channels (TCH/F + TCH/H + PDCH)
+
+
+== sysmoBTS
+
+image::images/symoBTS_v2D_front_1024.jpg[width="35%",role="gimmick_right"]
+
+* sysmocom builds family of GSM BTS based on OsmoBTS + OsmoPCU
+* revenue from this sales used to cross-subsidize OsmoBTS development
+* *osmo-bts-sysmo* uses shared-memory /dev to talk to PHY
+* *osmo-pcu* uses shared-memory /dev to talk to PHY

+|Model | RF Pwr |TRX|Outdoor|PoE | Quad-Band
+|sysmoBTS 1002 | 0.2 W | 1 | No | No | Yes
+|sysmoBTS 1002 OD | 0.2 W | 1 | Yes | Yes | Yes
+|sysmoBTS 1020 | 2.0 W | 1 | Yes | Yes | No

+
+image::images/litecell15.jpg[width="40%",role="gimmick_right"]
+
+* 10W 2-TRX Outdoor BTS
+* *osmo-bts-litecell15* uses shared-memory /dev to talk to PHY
+* *osmo-pcu* uses shared-memory /dev to talk to PHY
+
+
+== Octasic OCTBTS with OCTPHY-2G
+
+image::images/octbts_3600_photo__large.png[width="40%",role="gimmick_right"]
+
+* not a ready-to-deploy BTS product, more a BTS development board
+** no enclosure, no PA, no filters
+* proprietary PHY runs in Octasic DSP
+** raw Ethernet frames towards *osmo-bts-octphy*
+** unix domain pcu-socket to *osmo-pcu*
+* series of different board models (3000, 3500, 3600) with different
+ number of DSPs, radio interfaces, ARM/x86 processor core
+* two TRX per DSP possible
+* not all voice codecs supported
+* EGRPS integration with OsmoPCU not working yet
