Thanks a lot! We will try to integrate your suggestions in the next version
(to appear soon).

Dear all,

First I would like to thank the editor for the careful handling of our
suggestions. I tried to expand below the discussion on 3GPP technologies
usage in alternative networks, and provide links to relevant pointers.

Best regards,
Aldebaro

Current version:
6.2.1.2.  GSM
   GSM (Global System for Mobile Communications), from ETSI, has also
   been used in Alternative Networks as a Layer 2 option, as explained
   in [Mexican], [Village], [Heimerl].

Suggestion:
6.2.1.2.  GSM
   GSM (Global System for Mobile Communications), from ETSI, has also
   been used in Alternative Networks as a Layer 2 option, as explained
   in [Mexican], [Village], [Heimerl]. Open source GSM code such as
   [OpenBTS] and [OpenBSC] created an ecosystem with the participation
   of several companies [Range], [Endaga], [YateBTS] and deployments
   of voice, SMS and Internet services over alternative networks with
   an IP-based backhaul, for example. Internet navigation is restricted
   by relatively low bit rates [Osmocom].

   Benefiting from the evolution of 3rd Generation Partnership Project
   (3GPP) standards, a clear trend is the integration of 4G [IEEE-SDR],
   [YateBTS] or 5G [OpenAir] functionalities, with significant increase
   of achievable bit rates.

   Depending on factors such as the allocated frequency band, the
   adoption of licensed spectrum can have advantages over the
   eventually higher frequencies used for WiFi, with respect to signal
   propagation and, consequently, coverage. Other factors favorable
   to 3GPP technologies, especially GSM, are the low cost and energy
   consumption of handsets, which facilitate the digital inclusion of
   very low-income communities that cannot afford WiFi-enabled
   smartphones or face difficulties for charging them.

Opinion:

   Item 6.2.1.2 could be expanded to include other 3GPP technologies,

   such as 3G, 4G/LTE [IEEE-SDR] and 5G [OpenAir], mentioning systems

   such as [OpenBTS], [OpenBSC] and [YateBTS]. If this is reasonable, 

   I could try to expand it.

[JS] I think we must be as inclusive as possible. However, we have to report
only those technologies that are being used in real "Alternative networks".
Those ideas that are only in a first research stage can be reported, but
only as "recent efforts" or "future possibilities".

 

If you could expand the text, including these references, and stating the
current status of each of them, we can discuss it with the people in the
list.

 

Thanks,

 

Jose

draft-irtf-gaia-alternative-network-deployments

 

Hello,

I have recently joined the GAIA group and found
draft-irtf-gaia-alternative-network-deployments-03.txt very
interesting. I am not sure if this is the proper way of contributing,
but I am sending attached some suggestions.

PS: Our university (UFPA) has partnership with Brazilian
institutions to provide telephony services and Internet via GPRS to
underserved (and very poor) communities in the Amazon forest. We are
then biased towards using GSM due e.g. to the low cost of the handsets.

Regards,
Aldebaro
