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.
