I just purchased a Cisco 899G-LTE-GA-K9 router for a backup link should any of our site fibres become cut. It has a Telstra 4G sim card in it, but the performance of it thus far has been pretty woeful.
From what I understand, the MC7304 only supports one of the bands in which Telstra operates on, and it doesn’t support LTE-Advanced carrier aggregation. The most I can seem to get out of it is around 10-15mbps up and down. Cisco TAC have advised me that this is within the acceptable parameters for the device.
Here’s an output of the router where it currently sits… note the 10MHz bandwidth…
tsv-c899g-lte-01#sh cell 0 radio
Radio power mode = ON
LTE Rx Channel Number = 1300
LTE Tx Channel Number = 19300
LTE Band = 3
LTE Bandwidth = 10 MHz
Current RSSI = -63 dBm
Current RSRP = -92 dBm
Current RSRQ = -12 dB
Current SNR = 6.2 dB
Radio Access Technology(RAT) Preference = AUTO
Radio Access Technology(RAT) Selected = LTE
Does anyone know of any tweaks/hacks to milk a little bit extra out of it? Or am I doomed…
I note also that there is a newer chipset out now called the MC7430 which has LTE-A carrier aggregation and supports all of Telstra bands. Does anyone know if this device will work if I put it into the Cisco 899G-LTE-GA-K9 router?
The current flash firmware of the router is an spk file… MC7304_9999999_9902509_05.05.58.00_00_TELSTRA_005.021_000.spk
I’m figuring there may be a firmware available for the other chipset that I can dump in the flash for it to work… I may be ignorant however.
