I don't mind carrying another device in my pocket since I get a data connection that actually works reliably. I actually use the 4510L exclusively for the data plan on my Nexus S. I'm not sure if its a real signal or if the device is lying to me. The last couple weeks I've periodically seen phantom LTE signals with good stats (-60 dbm, 8 snr) but am so far unable to connect. LTE just went live in Salt Lake and my area *should* be getting it soon. I did about five speed tests in Vegas never broke 5mb and latency was never below 100ms. In my experience the 45010L had trouble switching between 3G/4G and required a reboot to get the signal back. I don't have LTE in my area yet, although I got to use it a little bit in Vegas. Its functional but the GUI is about as pretty as a linux shell.
#ANTENNA FOR VERIZON MIFI 4510L HOW TO#
I actually learned how to write an android app specifically so I could keep track of my data usage and view connection stats on my phone without being logged in the browser interface. My device is never further than arm's length and it would be great to turn down the wifi power.
Using my simple TS9 antenna and watching the signal report in the diagnostics menu showed that it definitely improved signal, at least when used in conjunction with CDMA2000 1x/EVDO. I happened to have a few TS9 antennas laying around, including one multi-band antenna which works well in the 800 / 1900 MHz bands Verizon uses for 1x/EVDO, unfortunately I didn’t have the foresight to have it with me when traveling to 700 MHz LTE markets. There’s a plastic flap which pries up revealing the TS9 jack underneath. The other important feature the 4510L brings is inclusion of an external antenna jack on the device. There’s no way to easily change this through the web front-end either. Again it’s a bit frustrating because having a very powerful WLAN radios might make sense if your particular use case is having the 4510L serve a household or small office temporarily, but isn’t desirable when you’re on battery power or again in a crowded environment. I was able to connect to the 4510L a surprising distance away, downstairs several rooms away from the 4510L and still have both decent RSSI and good enough MCS that typical EVDO performance wouldn’t be degraded at all. Range on the 4510L is quite far, in fact it’s almost too far. The best temporary solution is to move to the 5 GHz ISM which has many more non-overlapping channels, and propagation characteristics that will help keep signals confined to a single room instead of an entire venue. I got the opportunity to experience this firsthand with the 4510L at two conferences, it’s simultaneously fascinating and frustrating to experience. When that happens, it’d be useful to be able to use device-as-modem and tether over USB instead. I sound like a broken record, but it really is impossible to communicate just how much of a problem that is until you’re in a crowded room with 30 other APs all using the same 60 MHz of 2.4 GHz ISM bandwidth. WLAN connectivity is still limited to just the 2.4 GHz ISM band, which rapidly gets crowded and unusable at large gatherings. I didn’t go any further with my disassembly because of the delicate ZIF cable snaking around which leads to the e-ink display, and honestly most of what there is to find interesting was already on the this side. The contacts to the right of WCN1312 are simply for battery. The gold contacts on the far left are for cellular connectivity, and WiFi is at far right. Above the MDM9600 is the RTR8600 transceiver. You can see the MDM9600 sitting next to its attached Toshiba 1 Gbit (128 MB) NAND, and to the right of it the WCN1312. The MDM9600 must have a relatively beefy onboard ARM11 or something for this to be sufficient, and as we’ll show later there are similarities in the configuration portals that made this a dead giveaway even before I took a peek inside. What’s surprising (at least to me) about both the SCH-LCL is that both lack a discrete application processor for managing both the web front-end and the networking side of things (routing, firewall, NAT). Just like the Samsung SCH-LC11, at the core of the 4510L is a Qualcomm MDM9600 baseband which is responsible for both LTE and 1x/EVDO data connectivity, attached NAND, Qualcomm RTR8600 multi-band/mode RF transceiver, and a Qualcomm WCN1312 WLAN stack for single spatial stream 802.11n.
