gsm layer 1

Did you check official specification at h**p://www.3gpp.org/specs/specs.htm ?

ETSI spec is kind of unintelligible.
Can you tell me which chapter tell about layer 1 ?Thanks.

Anyone can tell me which document or book is good for layer 1 / protocol
understanding?
Thanks.

The book by Gunnar

Gsm Networks: Protocols, Terminology, and Implementation (Artech House Mobile Communications Library.)

is considered as a good book for GSM understanding at all layers including signalling.

The other book is

GSM Switching, Services, and Protocols
by Joerg Eberspaecher, Hans-Joerg Voegel, Christian Bettstetter

which also included two to three chapters over layer 1 and air interface,
Please use amazon.com to look for the contents of these books to see if this is realy what u are looking for ? .
