sarath 0 Report post Posted December 2, 2005 May be a silly question, but does any one know the exact frequency and polarisation of reliance signals? I want this information before I try to get some antennae from this provider. http://www.globalsources.com/gsol/I/Base-s.../1000839366.htm 12 to 15db should be more than enough to catch a really faint signal. Coupled with a protection filter made for the exact band, this would get most of the poor signal issues solved. YA-05 GSM/AMPS/CDMA Yagi Antenna for Cellular Phones Key Specifications/Special Features: * 6, 8, 10, 14 element available * Frequency: o 583.5MHz to 591.5MHz o 541MHz to 567MHz o 655MHz to 668MHz o 655.5MHz to 663.5MHz o 671.5MHz to 679.5MHz o 703.5MHz to 711.5MHz o 719.5MHz to 727.5MHz o 721MHz to 747MHz o 795MHz to 820MHz o 807.5MHz to 815.5MHz o 2.4GHz * Gain: 10dB to 15dB * System: GSM, AMPS, CDMA These are the supported frequencies of this antenna. Please advise. Regards, - Sarath Share this post Link to post Share on other sites

gsmsikar 0 Report post Posted December 2, 2005 it would be a great help if we can get the details of the frequency band of reliance cdma network, as there are many low network related problems , and we can cure them by using these types of antenna , and i dont think it is a secret issue of reliance / there are many vendors in the market who r selling antennas for reliance but are asking a hefty amount , and yagi antennas can be made at home , if we know the frequency details... thanks Share this post Link to post Share on other sites
kshah 452 Report post Posted December 3, 2005 use netmonitor or Diagnostic softwares to know what you want. For Kyocera use QXDM for LG LGDM and Nokia enable net monitor in handset to see details. google it to understand values displayed on handset. Else, YAGI is simple antena, you too can calculate and make. Calculations are simple mathematics. Share this post Link to post Share on other sites

Chirag 5 Report post Posted December 3, 2005 I got one such external booster antenna installed for myself, and when i saw it was wired thing coming till my office desk and getting attached to my cellphone, i got it removed the very same moment! I hate putting my cell on charging when i want to use it and they expect that the cell shud be connected to a wire! I guess, that was a very good example of last mile wired connectivity that i suggested for FWP Anyways, whats really a Yagi Antenna? How does it attach to the cellphone? Any snaps for examples?

ashoksoft 83 Report post Posted December 4, 2005 The master is back .... was away fiddling on TATA indicom handsets... coz someone is paying hefty to tweak somethings there Go for a AMPS(2) CDMA antenna. unless ur Access overload class value (specified by operator) is less than 10 the frequency of reliance network latch will be : Transmission (TX) : 824.64 MHz - 848.37 MHz Receiver (RX) : 869.64 - 893.37 Mhz Latch on presecion needs to be within 300 Hz of either limits. So any antenna which can support the said frequencies should ideally do.. Cheers Ashok Share this post Link to post Share on other sites
abhay 0 Report post Posted December 4, 2005 (edited) 90% of whateva u said went totally above my head but hearing so many technical terms im speechless Edited December 4, 2005 by abhay Share this post Link to post Share on other sites
ashoksoft 83 Report post Posted December 4, 2005 Lol that is simple mate... The transmission frequency is the frequency at which ur mobile transmits data, RX is the frequency at which the mobile receives data. AOC stands for ur CONSUMER status which is set by the operator. High values *(above 10) is meant only for VIP customers, and many a times is used by operator test mobiles. So when going to buy a network booster, u will need one which can boost signals in the said frequencies.... PS : Boosters DRAIN out batteries fast, and above that... they have an adverse effect on the life of the mobile too (despite all claims that they are 100% safe for the mobile) Cheers Ashok Share this post Link to post Share on other sites
linuxguy 0 Report post Posted December 4, 2005 I doubt CDMA operates at 800MHz frequency range. I think they operate at higher frequencies - 1800 or 1900MHz Share this post Link to post Share on other sites
ashoksoft 83 Report post Posted December 4, 2005 linuxguy u are guessing wrong... and there is nothing for u to doubt, coz the frequencies of operation can be confirmed from ur own handset.... or if u have a manual, they might have the info. 1800 - 1900 is in for GSM mate ... check out GSM specks 900 - 1800 will be for Dual band 900 - 1800 - 1900 will be Tri band 900 - 1800 - 1900 / 2100 - will be Tri band sub series (3G WCDMA) eg. 3.

linuxguy 0 Report post Posted December 5, 2005 Erm...I know those frequencies. Thats why I was a bit confused. I always thought CDMA operated at higher frequencies than GSM... Share this post Link to post Share on other sites
Puneet 0 Report post Posted December 5, 2005 (edited) Most of the times, if there are more then 2 operators in GSM 2 would be on 900 band and 2 on 1800. In Mumbai, BPL and Orange is on 900 (used to be when I used BPL) and Airtel was on 1800. While in Delhi, Airtel and Hutch were on 900 and Idea was on 1800. Am not sure about MTNL/BSNL. And in India CDMA is on 800 band. Check this link for GSM bands in India. Edited December 6, 2005 by Puneet Share this post Link to post Share on other sites
