GDW2000 Band 8 + 3 + 1 Explained: How the Tri-Band Enterprise Booster Covers EE, O2, Vodafone and Three Calls and 4G Across 2000m2 in the UK
The GDW2000 tunes three independent UK bands at once: Band 8 at 900 MHz for O2 and Vodafone 2G voice and SMS, Band 3 at 1800 MHz for EE and Three 4G LTE data, and Band 1 at 2100 MHz for the all-network 3G fallback, repeating each with >=65 dB uplink and >=70 dB downlink gain at >=27 dBm maximum output across 2000 m2 for up to 200 users, under Ofcom licence-exempt UKCA and CE rules.
Answer first: the GDW2000 is a tri-band FDD repeater that amplifies Band 8 (900 MHz), Band 3 (1800 MHz) and Band 1 (2100 MHz) in one 3.0 kg chassis, so a mixed-network UK enterprise site gets O2/Vodafone calls on 900 MHz, EE/Three 4G on 1800 MHz and shared 3G fallback on 2100 MHz without three separate boxes. This guide explains what each band does, which UK operators and MVNOs ride it, the exact uplink and downlink frequency pairs, the gain and output figures, why one tri-band chassis beats the dual-band GD2000 and GW2000, how VoLTE travels, and the honest Band 20 limitation for O2 and Vodafone 4G.
The unit amplifies Band 8 with an uplink of 890 to 915 MHz and a downlink of 935 to 960 MHz, Band 3 with an uplink of 1710 to 1785 MHz and a downlink of 1805 to 1880 MHz, and Band 1 with an uplink of 1930 to 1990 MHz and a downlink of 2110 to 2180 MHz. It delivers at least 65 dB uplink gain and at least 70 dB downlink gain per band, maximum output power of at least 27 dBm, up to 2000 m2 of indoor coverage and up to 200 simultaneous users. It carries UKCA and CE certification and operates under Ofcom's licence-exempt rules, so no frequency licence and no annual fee are required.
Before choosing any booster, understand that a unit can only repeat bands its radio physically tunes. A dual-band unit that omits a layer cannot manufacture it later, and a band the network allocates elsewhere, such as O2/Vodafone Band 20 at 800 MHz for rural 4G, stays outside this chassis no matter how high the Yagi climbs. The ten points below set the technical baseline before the deep-dive sections.
Quick Answer: What Exactly Does the GDW2000 Boost on Bands 8, 3 and 1 in the UK?
The GDW2000 boosts 2G GSM calls and SMS on Band 8, 4G LTE data on Band 3, and 3G UMTS fallback on Band 1, covering EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange and T-Mobile on the EE stack; Three, iD Mobile, Smarty, Plusnet and FreedomPop on the Three 4G stack; and O2, Vodafone, Giffgaff, Lebara, Lycamobile, Sky Mobile, Talkmobile, TalkTalk and Tesco on calls plus 3G. The numbered facts below set the baseline.
- Band 8 at 900 MHz carries 2G GSM voice and SMS. Uplink 890 to 915 MHz, downlink 935 to 960 MHz; it is O2 and Vodafone's widest rural calling layer and EE's 2G fallback where still broadcast.
- Band 3 at 1800 MHz carries 4G LTE data. Uplink 1710 to 1785 MHz, downlink 1805 to 1880 MHz; it serves EE and Three 4G capacity indoors.
- Band 1 at 2100 MHz carries 3G UMTS fallback. Uplink 1930 to 1990 MHz, downlink 2110 to 2180 MHz; it keeps a session alive on all four networks when LTE is congested or absent.
- Uplink gain is at least 65 dB and downlink gain at least 70 dB per band. The higher downlink figure restores tower signal through walls; the uplink restores the faint phone transmit back to the mast.
- Maximum output power is at least 27 dBm. That fixed ceiling is set under Ofcom licence-exempt limits and cannot be turned up manually.
- Coverage reaches up to 2000 m2 for up to 200 simultaneous users. The rating assumes a central panel with reasonable line of sight through the building.
- Tri-band beats dual-band. The GD2000 keeps Bands 8 and 3 only, and the GW2000 keeps Bands 8 and 1 only; each permanently drops one service layer.
- VoLTE travels over Band 3 on EE. 4G calling needs a supported handset and network registration; legacy phones still call over Band 8 2G.
- O2 and Vodafone Band 20 4G at 800 MHz is not covered. Those subscribers get boosted calls and 3G, not Band 20 rural 4G.
- The unit is UKCA and CE marked and Ofcom licence-exempt. No frequency application, annual fee or certified installer is required.
These ten points are the skeleton. The sections below expand each band, frequency pair, gain figure and network onto specific operators, MVNOs and real indoor behaviour, and the comparison table later in this guide shows exactly what GD2000 and GW2000 each miss.
Band 8 (900 MHz): O2 and Vodafone 2G Voice and SMS, the Rural Safety Net
Band 8 occupies the 900 MHz block and is the lowest-frequency layer in the GDW2000 kit. Lower frequency means a longer radio wave that bends over hills, wraps around tree trunks, penetrates stone walls and keeps coverage over large rural distances, which is why O2 and Vodafone built their widest voice footprint on it. The GDW2000 repeats the paired channels at 890 to 915 MHz for uplink (phone to tower) and 935 to 960 MHz for downlink (tower to phone).
What Band 8 actually carries
Band 8 delivers circuit-switched 2G GSM voice calls and SMS text messages. It is the layer a feature phone, an elderly relative's handset, a legacy handset and any phone that falls back from 4G uses when it needs the phone to ring. It is not a high-speed internet layer; data on 2G is slow by design, and the unit does not pretend otherwise. Its value is reliability of voice over the widest possible rural and stone-built footprint.
Which UK networks and MVNOs use Band 8 for calls
O2 and Vodafone depend on Band 8 for the bulk of their UK voice coverage, and the MVNOs hosted on those networks ride the same tower: Giffgaff, Lebara, Lycamobile, Sky Mobile, Talkmobile, TalkTalk and Tesco Mobile all place their calls on the O2 or Vodafone 2G layer. EE also broadcasts a slice of 900 MHz for 2G fallback in some areas, and Three maintains a narrow 2G voice presence in selected markets. Because the GDW2000 tunes the 890 to 915 MHz / 935 to 960 MHz pair, every voice call on those networks repeats indoors regardless of handset age.
Why 900 MHz reaches where 1800 MHz cannot
A 900 MHz wave loses less energy crossing foliage, soil, stone and gradient than a 1800 MHz wave, so a rural valley that shows one bar on 4G may still hold a usable 900 MHz donor reading. The >=65 dB uplink and >=70 dB downlink gain then restore that weak but present signal indoors. The trade-off: Band 8 carries far less capacity per channel than Band 3, which is why the unit keeps data on Band 3 and voice on Band 8 rather than expecting 900 MHz to do both jobs well.
Band 3 (1800 MHz): EE and Three 4G LTE Data and the VoLTE Layer
Band 3 occupies the 1800 MHz block tuned with a 1710 to 1785 MHz uplink and an 1805 to 1880 MHz downlink pair. This is the mainstream 4G LTE data layer in the GDW2000, the session that loads video calls, card terminals, email attachments and browsing inside the building. EE builds a large share of its UK LTE capacity on Band 3, and Three also allocates 1800 MHz spectrum for its 4G.
What Band 3 actually carries
Band 3 carries 4G LTE packet data: download, upload, ping and the internet session that modern phones live on. It also carries VoLTE, which is voice handled as data over LTE instead of the old circuit-switched 2G path. A boosted Band 3 link turns a dead-zone office into a place where video conferencing and guest pages load, which 2G and 3G cannot match in speed.
Which UK networks and MVNOs use Band 3 for 4G
EE customers receive Band 3 4G directly, and MVNOs hosted on EE ride the same 1800 MHz cell: BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator. Three customers receive Band 3 4G as well, and its MVNOs iD Mobile, Smarty Mobile, Plusnet Mobile and FreedomPop follow. The GDW2000 boosts this layer for both camps, which is why a mixed office with EE and Three SIMs all gets usable data on Band 3 rather than only one operator.
VoLTE: 4G calling over Band 3
VoLTE, or voice over LTE, places a phone call as a data session inside the Band 3 LTE connection instead of dropping the call down to 2G. It requires a handset that supports VoLTE, a network that registers it, and a clear LTE donor; once those three line up, the boosted Band 3 link carries the call in HD quality. Where VoLTE is unavailable, the phone falls back to Band 8 2G voice, which the GDW2000 also boosts, so the call still completes on an older phone.
Band 1 (2100 MHz): The Shared 3G UMTS Fallback for All Four Networks
Band 1 occupies the 2100 MHz block tuned with a 1930 to 1990 MHz uplink and a 2110 to 2180 MHz downlink pair. It carries 3G UMTS, the older data layer that every UK operator still maintains as a fallback when 4G is congested, absent indoors or unsupported by the handset. The GDW2000 boosts Band 1 on top of calls and 4G, which is the feature a dual-band unit cannot offer.
What Band 1 actually carries
Band 1 carries 3G packet data that keeps a basic session alive: a search result, a booking page, a card terminal, an email check. It is slower than LTE by design and built for continuity rather than peak throughput. When the Band 3 donor cell is full at lunchtime, checkout or peak trading, the handset hands over to Band 1, and a boosted Band 1 keeps that session connected instead of showing no service.
Which UK networks use Band 1 for 3G
All four UK operators, O2, Vodafone, EE and Three, keep a Band 1 3G layer as fallback, and their MVNOs inherit it through the host network. That means an O2 or Vodafone subscriber who cannot receive Band 20 4G still gets Band 1 3G indoors via the GDW2000, and an EE or Three subscriber whose LTE cell is busy drops onto Band 1 rather than losing data. The shared nature of Band 1 is what makes the third band valuable in a mixed-network building.
Why a third band matters more than extra gain
A stronger amplifier on the wrong band still cannot serve a missing layer. Boosting Band 8 and Band 3 with higher gain does not create Band 1 3G, just as boosting Band 8 and Band 1 does not create Band 3 4G. Tuning all three pairs in one chassis is the architectural difference between the GDW2000 and the dual-band siblings, and it is the reason the 200-user, 2000 m2 rating holds across mixed traffic.
The Exact Uplink and Downlink Frequency Pairs for Bands 8, 3 and 1
Each FDD band uses a paired block: a lower uplink channel where the phone transmits and a higher downlink channel where the tower transmits, separated by a guard gap so the two directions do not collide. The GDW2000 repeats both directions of every pair simultaneously.
| Band | Service | Uplink (phone to tower) | Downlink (tower to phone) | Primary UK users |
|---|---|---|---|---|
| Band 8 | 2G GSM calls and SMS | 890 to 915 MHz | 935 to 960 MHz | O2, Vodafone and hosted MVNOs; EE 2G fallback |
| Band 3 | 4G LTE data and VoLTE | 1710 to 1785 MHz | 1805 to 1880 MHz | EE, Three and their hosted MVNOs |
| Band 1 | 3G UMTS fallback | 1930 to 1990 MHz | 2110 to 2180 MHz | All four networks and hosted MVNOs |
The gap between uplink and downlink keeps the phone's faint transmit separate from the tower's loud receive, and the AGC on the GDW2000 balances each pair independently. A phone field-test app lists the serving frequency per band, which is how you confirm which pair your donor cell sits on before mounting the Yagi.
Which UK Networks and MVNOs Receive Which Service on the GDW2000
The table below maps each operator and hosted MVNO to the service stack the GDW2000 actually delivers, so a mixed-network workplace knows exactly what arrives on every SIM. The split follows the host network, because an MVNO does not own its own mast.
| Operator group | Networks and MVNOs | Band 8 calls | Band 3 4G | Band 1 3G |
|---|---|---|---|---|
| EE full stack | EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile, The People's Operator | Boosted (2G fallback) | Boosted | Boosted |
| Three 4G stack | Three, iD Mobile, Smarty Mobile, Plusnet Mobile, FreedomPop | Boosted where present | Boosted | Boosted |
| O2/Vodafone calls and 3G | O2, Vodafone, Giffgaff, Lebara, Lycamobile, Sky Mobile, Talkmobile, TalkTalk, Tesco | Boosted | Not Band 20 4G | Boosted |
Read the middle row carefully: Three and its MVNOs receive boosted Band 3 4G plus Band 1 3G and Band 8 calls where Three broadcasts 2G. Read the bottom row even more carefully: O2 and Vodafone subscribers receive boosted calls on Band 8 and boosted 3G on Band 1, but their rural Band 20 800 MHz 4G is outside this unit.
Gain >=65 dB Uplink and >=70 dB Downlink, Output >=27 dBm Explained
Gain measures how much the amplifier restores a weak signal; output measures the fixed ceiling of what it may legally re-radiate indoors. The two numbers work together but mean different things, and the GDW2000 keeps them separate per band.
Why uplink and downlink gain are not equal
The tower transmits with far more power than a phone battery can, so at the donor Yagi the downlink signal arrives stronger and the uplink return path starts weaker and loses more through building materials. The GDW2000 applies at least 65 dB uplink gain to lift the phone's faint transmit back toward the tower, and at least 70 dB downlink gain to restore the tower signal through concrete, steel and partitions to the panel. The extra 5 dB on downlink compensates the deeper indoor path rather than boosting everything equally.
What >=27 dBm maximum output means
Output power of at least 27 dBm is the legal ceiling under Ofcom's licence-exempt repeater rules, not a dial you can crank higher. The automatic gain control sits at or below that limit on every band, trims oscillation before it reaches the serving tower, and never overshoots. Turning output up manually is neither possible nor legal, which is why the unit has no gain knob and relies on geometry, aim and separation instead.
How the numbers map to 2000 m2 and 200 users
The combined >=65 dB uplink and >=70 dB downlink budget, held at >=27 dBm output, gives the boosted cell enough headroom to cover 2000 m2 and keep up to 200 active sessions attached. That headroom shrinks with steel racking, concrete slabs and long panel runs, which is why the rating assumes a central panel and reasonable line of sight rather than an open field benchmark.
Why Tri-Band 8+3+1 Beats the Dual-Band GD2000 and GW2000
The GD2000 tunes Band 8 and Band 3, and the GW2000 tunes Band 8 and Band 1. Both are rated for 2000 m2 but each permanently omits one service layer, and neither can add that layer later with a setting change. The GDW2000 keeps all three pairs in one chassis.
| Feature | GDW2000 tri-band | GD2000 dual-band 8+3 | GW2000 dual-band 8+1 |
|---|---|---|---|
| Bands tuned | 8, 3, 1 (900/1800/2100 MHz) | 8, 3 (900/1800 MHz) | 8, 1 (900/2100 MHz) |
| O2/Vodafone 2G calls | Boosted | Boosted | Boosted |
| EE/Three 4G LTE Band 3 | Boosted | Boosted | Missing entirely |
| All-network Band 1 3G fallback | Boosted | Missing entirely | Boosted |
| Coverage / users | 2000 m2 / 200 users | 2000 m2 rated | 2000 m2 rated |
| Gain per band | >=65 dB up / >=70 dB down | 8+3 only | 8+1 only |
| Best fit | Mixed-network enterprise site | EE/Three-only 4G and calls site | Voice and 3G rural site |
What a GD2000 buyer misses
The GD2000 keeps calls on Band 8 and 4G on Band 3, so an EE or Three-only building works well, but it has no Band 1 radio. When LTE is congested or absent, there is no 3G fallback to land on, and O2/Vodafone 3G disappears indoors too. Adding Band 1 later requires a second booster rather than a setting.
What a GW2000 buyer misses
The GW2000 keeps calls on Band 8 and 3G on Band 1, so a voice and data-fallback rural site works well, but it has no Band 3 radio and cannot manufacture EE or Three 4G LTE at any gain. A building that needs fast data on 1800 MHz stays limited to 3G speed.
The GDW2000's third band removes both trade-offs: calls, 4G and 3G fallback coexist for every operator in one Ofcom-legal, UKCA and CE box.
The Honest Limitation: O2 and Vodafone Band 20 (800 MHz) 4G Is Not Covered
Important: O2 and Vodafone place much of their rural 4G LTE on Band 20 at 800 MHz. The GDW2000 tunes Bands 8, 3 and 1 only, so it cannot repeat Band 20. An O2 or Vodafone customer therefore receives boosted Band 8 calls and SMS and boosted Band 1 3G indoors, but not Band 20 rural 4G data. EE and Three customers are unaffected because their 4G runs on Band 3.
What this means in practice
An O2 or Vodafone subscriber in a rural valley who relies on Band 20 4G for fast internet will not see that 4G restored indoors, even though calls become clear. That same subscriber can still make and receive calls, send SMS and hold a slow Band 1 3G session. A site dominated by O2/Vodafone 4G on 800 MHz should confirm the donor band outdoors before ordering, rather than assuming every 4G frequency is covered.
Do not confuse Band 20 with Band 8
Band 20 at 800 MHz and Band 8 at 900 MHz sit close together on the dial but are different channels with different services: 800 MHz carries O2/Vodafone LTE 4G, while 900 MHz carries 2G voice. A field-test app distinguishes the two by the band number, not by a visual similarity, so check the band label before concluding the donor is present.
Ofcom Licence-Exempt Status, UKCA and CE Compliance
The GDW2000 operates under Ofcom's licence-exempt repeater rules, which means no frequency application, no annual licence fee and no certified installer are required for normal indoor use on a UK business or residential site. The fixed >=27 dBm output ceiling and per-band AGC keep the unit within those limits automatically, so the owner does not tune output by hand.
UKCA and CE marks
The chassis carries UKCA and CE certification, confirming it meets UK and European equipment requirements for the tuned bands, safety and emissions. The AC adapter accepts 100 to 240 V 50/60 Hz and steps down to DC 5 V with a UK 3-pin plug, so it plugs into a standard UK mains socket without a transformer or travel adapter.
Owner obligations that remain
Licence-exempt does not mean license-free in every condition: the owner still must keep antennas separated to avoid interfering with the serving tower, use the unit indoors as intended, and not re-aim or modify the radio. A single external Yagi normally sits within permitted development in England and Wales, but leaseholds, listed buildings and conservation areas deserve a quick landlord or local planning check before drilling.
In closing: the GDW2000 earns its enterprise position because it repeats all three UK service layers in one box, Band 8 900 MHz calls and SMS, Band 3 1800 MHz EE and Three 4G LTE and VoLTE, and Band 1 2100 MHz all-network 3G fallback, paired as 890-915/935-960, 1710-1785/1805-1880 and 1930-1990/2110-2180 MHz, held at >=65 dB uplink and >=70 dB downlink gain under a fixed >=27 dBm Ofcom-legal output for 2000 m2 and 200 users. The GD2000 drops Band 1 and the GW2000 drops Band 3, while the GDW2000 keeps every service; the one honest gap is O2 and Vodafone Band 20 800 MHz rural 4G, which this unit does not tune. With UKCA and CE marks and Ofcom licence-exempt status, mixed-network calls, data and fallback arrive indoors without a licence or contractor.
Frequently Asked Questions
What is Band 8 (900 MHz) and why is it O2 and Vodafone's default 2G voice band across UK rural coverage?
Band 8 at 900 MHz is the sub-gigahertz layer where O2 and Vodafone still carry 2G GSM voice calls and SMS across the widest rural footprint in the UK. Its longer wavelength bends over hills, through stone walls and around trees that block higher bands, which is why the GDW2000 tunes the 890 to 915 MHz uplink and 935 to 960 MHz downlink pair specifically to rescue indoor calling on those two networks. EE also uses a slice of 900 MHz for 2G fallback where it still broadcasts, so Band 8 is the safety net that keeps the phone ringing even when 4G and 3G are absent.
How does Band 3 (1800 MHz) carry EE 4G LTE, and why does Three also use 1800 MHz for its UK 4G?
Band 3 at 1800 MHz is the mainstream 4G LTE layer tuned with a 1710 to 1785 MHz uplink and 1805 to 1880 MHz downlink pair. EE builds most of its capacity on this band, and Three also allocates spectrum at 1800 MHz for its 4G data sessions, so the GDW2000's Band 3 path serves EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator on the EE side, plus Three, iD Mobile, Smarty, Plusnet and FreedomPop on the Three side. Band 3 carries the fast data session that Band 8 and Band 1 cannot provide.
What role does Band 1 (2100 MHz) play as the shared 3G UMTS fallback layer for all four UK networks?
Band 1 at 2100 MHz, paired as 1930 to 1990 MHz uplink and 2110 to 2180 MHz downlink, carries 3G UMTS data for every UK operator including O2, Vodafone, EE and Three. When the Band 3 LTE cell is congested or absent, the phone falls back to a Band 1 session that keeps browsing, card terminals and booking pages alive. The GDW2000 boosts this layer on top of calls and 4G, which is what separates a tri-band unit from a dual-band one and keeps data moving in rural and basement locations.
Why does the GDW2000 miss O2 and Vodafone Band 20 (800 MHz) rural 4G, and what do those subscribers still get indoors?
O2 and Vodafone place much of their rural 4G LTE on Band 20 at 800 MHz, a frequency the GDW2000 does not tune, so it cannot manufacture that 4G indoors for those two networks. The honest result: an O2 or Vodafone subscriber still receives boosted Band 8 2G calls and SMS and Band 1 3G fallback, but not Band 20 4G data. EE and Three customers are unaffected because their 4G runs on Band 3, which the unit does boost. Anyone buying purely for O2 or Vodafone rural 4G on 800 MHz should check the band before ordering.
How much bandwidth sits inside the 900, 1800 and 2100 MHz blocks, and why do Band 3 sessions feel faster than Band 1?
Band 3 at 1800 MHz carries the widest LTE channel allocation in this kit, giving the cleanest, highest-capacity data session once the phone decodes it. Band 1 at 2100 MHz is an older 3G UMTS layer designed to keep a session alive rather than deliver peak speed, which is why a Band 1 page loads but a large upload waits. Band 8 at 900 MHz prioritises reliable voice over data throughput. The GDW2000 treats each layer independently with >=65 dB uplink and >=70 dB downlink gain, so the phone keeps whichever service the network offers in that moment.
How does the >=70 dB downlink gain compensate wall, floor and steel loss across a 2000 m2 enterprise building?
As the tower signal travels from the donor Yagi through concrete slabs, steel racking, metal ducts and multiple partitions, it loses power at every surface. The >=70 dB downlink gain on the GDW2000 restores that lost budget before re-radiating through the 5 dBi panel, and the >=65 dB uplink gain does the same on the phone-to-tower path. A higher downlink figure than uplink is normal because the indoor phone starts with far less transmit power than the tower; this margin is what lets the rated 2000 m2 and 200-user footprint hold across a warehouse or hotel rather than a single room.
Do boosted Band 8 2G calls still work on older phones that lack VoLTE and 4G calling support?
Yes. Band 8 is the circuit-switched 2G GSM layer, so a basic or older handset that cannot register VoLTE or 4G calling still completes a normal voice call over 900 MHz once the Yagi picks the donor up. The booster does not require a modern handset; it repeats whatever the network sends on the tuned bands. This matters for O2 and Vodafone households with elderly relatives' phones, legacy two-way radios and feature phones that will never support 4G calling.
If you removed Band 8, Band 3 or Band 1 one at a time, which call, SMS or data service would stop working?
Remove Band 8 and O2/Vodafone 2G calls and SMS vanish, leaving those subscribers silent indoors. Remove Band 3 and EE and Three 4G LTE data disappears, dropping everything back to 3G. Remove Band 1 and the all-network 3G fallback disappears, so a congested or absent 4G session has nowhere to land. Keeping all three bands in one chassis is exactly why the GDW2000 covers calls, SMS, 4G data and 3G fallback where a dual-band unit drops one service permanently.
How does the 200-user rating connect to the shared >=27 dBm output and network scheduling at peak occupancy?
The GDW2000 supports up to 200 simultaneous active sessions because its >=27 dBm maximum output and >=70 dB downlink margin give the boosted cell enough headroom to keep many phones attached at once. The serving tower, not the booster, decides how to schedule each phone's airtime beyond that point; approaching 200 concurrent calls simply means the network throttles naturally rather than the unit failing. This rating suits a 30 to 60 person office, a hotel or a mid-size warehouse, not a stadium.
When the Band 3 donor cell is congested, does the GDW2000 move a phone onto Band 1 3G automatically?
The phone and network decide the handover; the booster repeats whatever band the network hands the phone onto. When the Band 3 LTE cell is full at checkout or lunchtime, the handset autonomously falls back to a Band 1 3G session, and because the GDW2000 also boosts Band 1, that fallback stays connected indoors instead of dropping to zero bars. The unit does not force a band change itself, but keeping Band 1 boosted guarantees the fallback works when the network invokes it.
